The federal, provincial, and territorial government signatories under the Accord for the Protection of Species at Risk (1996) agreed to establish complementary legislation and programs that provide for effective protection of species at risk throughout Canada. Under the Species at Risk Act (S.C. 2002, c.29) (SARA), the federal competent ministers are responsible for the preparation of management plans for listed species of special concern and are required to report on progress five years after the publication of the final document on the SAR Public Registry.
The Minister of the Environment and the Minister responsible for the Parks Canada Agency are the competent ministers under SARA for the Black-footed Albatross and have prepared this management plan as per section 65 of SARA. To the extent possible it has been prepared in cooperation with Fisheries and Oceans Canada and the Province of British Columbia.
Success in the conservation of this species depends on the commitment and cooperation of many different constituencies that will be involved in implementing the directions set out in this plan and will not be achieved by Environment Canada and the Parks Canada Agency, or any other jurisdiction alone. All Canadians are invited to join in supporting and implementing this plan for the benefit of the Black-footed Albatross and Canadian society as a whole.
Implementation of this management plan is subject to appropriations, priorities, and budgetary constraints of the participating jurisdictions and organizations.

The Black-footed Albatross is a long-lived seabird that breeds mainly in the Northwestern Hawaiian Islands and occurs at sea off the Pacific Coast of Canada during the breeding and non-breeding seasons. Significant numbers feed off the coast of British Columbia each year, including adults making long foraging trips to feed their young.
The population seems generally stable, but relatively high numbers are caught as bycatch in longline fisheries in the North Pacific. Additionally, adults and immature birds are affected by the accumulation of toxic chemicals and heavy metals and by the ingestion of waste plastics from the surface of the sea when they are feeding. Because of the unknown effect of these particular threats over the long term, the Black-footed Albatross has been listed as a species of Special Concern in Canada. Emerging threats such as the potential loss of nesting and foraging habitat due to climate change also threaten this species.
The management objective for the Black-footed Albatross is to"… help to increase global population numbers and maintain the population throughout its documented distribution in Canadian waters, by reducing at-sea mortality and otherwise augmenting international conservation efforts." The conservation of the Black-footed Albatross cannot succeed by Canadian efforts alone due to the wide-ranging marine nature and distant nesting habitats of this species.
Actions already underway include long-term at-sea surveys that record Black-footed Albatross distribution and abundance in Canada, and assessments of longline bycatch mortality in Canadian Pacific waters, including monitoring of current bycatch levels. Bycatch mitigation measures have been implemented in the target fishing fleet, but monitoring for compliance and effectiveness is limited and should be increased. Strategies and measures to achieve the management objectives are presented in the section entitled Broad Strategies and Conservation Measures.
1. COSEWIC species assessment information
- Date of Assessment
- April 2007
- Common Name (population)
- Black-footed Albatross
- Scientific Name
- Phoebastria nigripes
- COSEWIC Status
- Special Concern
- Reason for Designation
- This long-winged, long-lived (up to 40 years) seabird breeds on remote islands primarily in the Hawaiian chain, but significant numbers feed off the coast of British Columbia each year, including adults making long foraging trips to feed their young. Black-footed Albatross numbers declined at one of two major colonies in the 1990s, but the population seems generally stable or possibly slowly increasing. Some population models have predicted serious declines, while others predict stable populations. Many are caught as bycatch in longline fisheries, most suffer from ingestion of plastic and accumulate high levels of pollutants, but the long-term effects of these threats are unclear.

3. Species information
3.1. Species description
The Black-footed Albatross (Phoebastria nigripes Audubon 1839) is a relatively small member of the albatross family and one of four albatross species regularly found in the Northern Hemisphere. Adult birds are distinguished from other albatross species in the North Pacific by their dusky brown plumage, whitish area around the base of the bill and under the eye and white plumage over the base of the tail and undertail coverts. Immature birds have darker plumage than adults and lack the white upper and undertail coverts (Hyrenbach et al. 2002). Males have a larger head size than females (Smith et al. 2010). The Black-footed Albatross lives for at least 40 years, with banding records showing the oldest bird as being 45+ years. Like many other seabird species, Black-footed Albatross exhibit a monogamous mating system that lasts a lifetime unless their mate disappears or dies. Birds typically begin breeding at the age of seven or eight (Rice and Kenyon 1962) and produce a single egg per breeding season. Details on natural history and biology of the Black-footed Albatross are provided in the COSEWIC (2006) status report for the species, with many additional references provided therein.
3.2. Population and distribution
Black-footed Albatross are currently known to nest at 15 sites throughout the tropical/subtropical North Pacific Ocean, with approximately 95% of the population breeding entirely within the Northwestern Hawaiian Islands (NWHI; Agreement on the Conservation of Albatrosses and Petrels [ACAP] 2011; Fig 1) and protected in the Papahānaumokuākea Marine National Monument. COSEWIC (2006) reported a total of 12 nesting sites, but three other intermittent sites are listed by ACAP (2011).
The global population has been estimated at between 278,000 and 300,000 individuals (presumably including non-breeding birds at sea; Cousins & Cooper 2000; BirdLife International 2004a, b). The most recent global estimate of breeding birds is of 66,377 pairs, with approximately 63,273 breeding pairs in the central Pacific (Hawaiian island chain; unpublished data ACAP 2014). Its nesting distribution means the species is vulnerable to localised threats; just four colonies (Midway Atoll, Laysan Island, Pearl and Hermes Reef, and French Frigate Shoals [FFS]) account for approximately 88% of the world’s breeding population. Four small colonies (about 5% of the world’s breeding pairs) are situated on islands off the coast of Japan (ACAP 2011). In 1998 and 2000 the first reported breeding for this species east of Hawaii was recorded in Mexico (Guadalupe and San Benedicto Island; no breeding documented since; Pitman and Ballance 2002; ACAP 2011). Several large central and western Pacific colonies historically extirpated by the feather trade have not been recolonized (Arata et al. 2009), though a few pairs recently made unsuccessful attempts to nest at Wake Island (central Pacific; Arata et al. 2009). New analyses based on nest count data from Midway, Laysan, and FFS from 1992–2014, 1998–2012, and 1980–2011 showed linear trends in populations that were positive (1.5% per annum), negative or presumed stable (-0.02% per annum), and presumed stable (0.6% per annum), respectively (ACAP 2011; see COSEWIC (2006) for previous analyses). Footnote 1
At sea, the Black-footed Albatross is widespread throughout the North Pacific, ranging from 20°–58°N (Cousins and Cooper 2000). The population occurs in international waters as well as in the Canadian Exclusive Economic Zone (EEZ) off British Columbia (BC). They are most often found along the continental shelf and shelf break, over seamounts and other areas with steep bathymetry, and quite frequently near shore (Kenyon et al. 2009; Fig. 2). The waters of British Columbia are important for Black-footed Albatross, particularly along the shelf break, where upwelling and high prey populations create reliable sources of food for these birds. Historically, Black-footed Albatross were regular visitors to the BC Coast. This is the only albatross species seen regularly in Canadian waters at present (COSEWIC 2006).
Ship-based observations and studies show that Black-footed Albatross numbers in BC peak from May to September, particularly in August and early September when adult birds and young of the year disperse from their Hawaiian colonies. In late September to early October breeders return to their nesting colonies and are present in lower numbers from December to April (COSEWIC 2006). There is no trend analysis for the species in Canadian waters.
3.3. Needs of the Black-footed Albatross
The Black-footed Albatross is long-lived, with delayed age of first breeding, low fecundity, and high adult survival rates (Whittow 1993). The species is thus extremely vulnerable to any changes in natural rates of adult mortality, with demographic models showing that population change is most affected by adult survival (Cochrane and Starfield 1999). It is also a highly pelagic, island-nesting species that needs predator-free areas for nesting and for year-round foraging; requires large, productive marine habitats free from human disturbances and disruptions in their prey populations (COSEWIC 2006). The tendency for this species to often forage up to several thousands of kilometres from their breeding sites is most relevant to Canada's Management Plan. Adult Black-footed Albatrosses visit Canada's Pacific EEZ to forage during the breeding and post-breeding season, and immature birds are likely present in Canadian waters year round.
The need for disturbance-free nesting habitat is primarily compromised by introduced predators, particularly at historical colonies that have yet to be reoccupied. On land, Black-footed Albatrosses need predator-free nest sites because they are vulnerable for up to six months while they breed. Once their chick hatches, adults need to remain close to guard the chick and feed it frequent, small meals. During this time both adult and chick are tied to the colony and its vicinity for survival. As chicks age they need larger meals and may be left alone for days or weeks at a time while the parent forages at sea. Once chicks reach 18-20 days of age, a breeding adult will expand its foraging range to access cold, nutrient-rich waters north and east of the colonies, including along North America’s continental shelf, from central California to BC (Hyrenbach et al. 2002; Kappes et al. 2010). Once chicks leave the colony, breeding adults will also depart, dispersing across the North Pacific and remaining at sea until the next breeding season (e.g., Hyrenbach and Dotson 2003).
Albatrosses are surface predators and scavengers, requiring productive marine habitats during all life stages to feed primarily on squid and flying fish eggs and opportunistically on discarded fishing bait. Their selection of marine habitats is mediated by both food distribution and wind patterns (Croxall et al. 2005). Seamounts are important oceanic features for albatrosses, presumably due to oceanic upwelling and increased food concentrations; in Canada, Black-footed Albatrosses appear to concentrate over shallow seamounts such as Bowie (K. Morgan unpublished data). Near the North American continent, the species is most abundant over the outer continental shelf, particularly at the shelf break, another area of high food concentration (Morgan et al. 1991; Whittow 1993; Kenyon et al. 2009). In summary, breeding birds require marine habitats with abundant prey populations, both near and far from their colonies, and in Canada they use seamounts, the continental shelf, and shelf break habitats, so these areas need to be free from human disturbance or threats.
All the Canadian and international threats identified in the species’ status report (COSEWIC 2006) are included in the following table and narrative. Two new threats identified since the status report was completed are also included here (collisions with vessels and active fishing gear, and tsunamis during the nesting season).

4.2 Description of threats
Demersal longline fisheries bycatch
Fisheries bycatch, or incidental take, is the most serious threat facing Black-footed Albatrosses in Canada and globally (COSEWIC 2006; Arata et al. 2009). In Canada, the greatest fisheries threat occurs in the demersal longline fishery when baited hooks are set behind a vessel and albatross are able to access and swallow the hooks before they sink, resulting in their drowning as the longline is set along the sea floor. The Black-footed Albatross exhibits a strong degree of spatial and temporal overlap with Canadian commercial groundfish hook and line fisheries; especially those targeting Pacific halibut (Hippoglossus stenolepis), sablefish (Anoplopoma fimbria), rockfish (Sebastes spp.) and spiny dogfish (Squalus acanthias), which are concentrated on the continental shelf (Wiese and Smith 2003; Smith and Morgan 2005). This places breeding and post-breeding adults at risk of being caught as bycatch. Smith and Morgan (2005) reported that Black-footed Albatrosses were the most frequently caught seabird in west coast Canadian demersal longline fisheries, with a predicted average of about 90 albatrosses killed each year (data from 1999-2002 halibut and rockfish fisheries). In the late 1990s and early 2000s the highest bycatch in BC occurred at Bowie Seamount during a permitted charter longline fishery for rockfish, indicating high densities at this location (Smith and Morgan 2005). This fishery is now closed and two thirds of Bowie Seamount is a federal Marine Protected Area (MPA). In this Management Plan, fisheries mortality is rated the highest priority because of three pieces of information: (1) a relatively high rate of Black-footed Albatross bycatch in monitored or observed demersal longline fisheries in Canada, and in other fisheries (demersal and pelagic) elsewhere in the North Pacific; (2) the lack of data on bycatch and fisheries effort for several foreign pelagic longline fisheries where bycatch rates are thought to be higher (e.g., US west coast demersal fishery, Russian and Asian fleets; Arata et al. 2009); and (3) the aforementioned life history characteristics of this species that make the overall population extremely vulnerable to increases in adult mortality rates (COSEWIC 2006; Arata et al. 2009).
As surface feeders, Black-footed Albatross inadvertently consume floating plastic objects and susceptibility to plastic ingestion has been ranked "high" for this species, especially for chicks (Nevins et al. 2005; COSEWIC 2006). Although population-level impacts of widespread plastic ingestion have been hard to quantify, the known harmful effects to individuals include dehydration, reduction of stomach volume, internal injury from plastic objects, and starvation (Sievert and Sileo1993). The greatest threat posed by plastic ingestion is starvation and dehydration of chicks because parents regurgitate the plastic pieces to them during feeding. Indirectly, ingested plastics may also facilitate the accumulation of organochlorines in all seabirds as these contaminants may adsorb to plastic particles (Naughton et al. 2007).
At Black-footed Albatross colonies, historically introduced predators such as rats and cats have caused population declines and extirpations through depredation of eggs, chicks and adults. Introduced predators have all been eradicated from colonies in the NWHI but are still present in Hawaii proper and at islands historically or recently occupied by nesting albatrosses, and may prevent or limit colonization or re-colonization of these sites.
Contaminants are a current, recurrent threat to the Black-footed Albatross as both chicks and adult birds are susceptible to the bioaccumulation of environmental pollutants such as organochlorines and heavy metals obtained from their marine diet (Jones et al. 1996; Aguilar et al. 2002; Bjerregaard et al. 2001; Tchounwou et al. 2003). At sufficiently high levels these chemicals, particularly organochlorines, can produce altered immune functions, resulting in altered physiological functions and compromised immunological status. Concentrations of organochlorines in Black-footed Albatross tissues have increased by 100% in the last decade, leading to increased mortality and population level concerns (Finkelstein et al. 2006, 2007; Arata et al. 2009).
Chronic oil pollution and catastrophic oil spills
Chronic oil pollution (e.g., via illegal discharge of contaminated bilge water) and large catastrophic oil spills are an on-going, recurrent threat to all seabirds in Canada, including Black-footed Albatross. When birds come into contact with floating oil at sea it accumulates on their feathers, reducing waterproofing, thermoregulation and buoyancy, and leading to reduced fitness or survival. The majority of Black-footed Albatrosses have been observed along the Canadian continental shelf break, an area bisected by commercial shipping traffic, resulting in high potential to encounter either chronic discharges or a catastrophic spill from shipping traffic during the summer and fall. To date (2014), federal and provincial moratoriums for oil and gas exploration off the BC coast are in place, but there have been recent discussions concerning the potential lifting of these moratoriums, and coastal shipping of oil and condensate is projected to dramatically increase in the next decade with export to Asia and liquid natural gas development in northern BC (COSEWIC 2006).
Tsunamis during nesting season
Tsunamis are a recurrent and anticipated threat to Black-footed Albatross that were not identified in the COSEWIC (2006) report. In March 2011, a tsunami generated by a 9.0-magnitude earthquake in Japan washed over the Midway Atoll National Wildlife Refuge and other islands in the NWHI, killing over 110,000 Laysan (P. immutabilis) and Black-footed Albatross chicks and about 2,000 adults (USFWS 2011; breakdown by species was not available, though Black-footed Albatross nest closer to the shoreline than do Laysan Albatross). Estimates for other affected islands such as Laysan were less accurate, but the USFWS (2011) estimates that many more thousands of albatross chicks were lost. A tsunami is also known to have inundated Midway Atoll in 1952 (D. Duffy in litt.).
Climate change and inundation of breeding sites
An increase in sea level, as a result of climate change, is of particular concern for Black-footed Albatrosses nesting on low-lying atolls in the tropical North Pacific, where about 95% of the world's population breeds. Some of these sites, just one or two metres above sea level, are among the world's most vulnerable to inundation and consequent loss of beach nesting areas or even the disappearance of entire atolls (Baker et al. 2006).
Competition with fisheries for foods
Competition with commercial fisheries for food is a potentially recurrent threat for Black-footed Albatrosses in Canada and range-wide. Squid forms up to 30% of their diet and in locations where there are currently directed squid fisheries, such as Japan and the North Pacific, this threat may cause albatrosses to spend more time foraging if local prey populations are depleted. Surface scavenging is an important foraging strategy for this species, thus the effects of competition may be partially offset by the availability of discards from fishing vessels if they discard at sea (COSEWIC 2006).
Invasive plant species, particularly ironwood (Casuarina equisetifolia), and golden crown-beard (Verbesina encelioides) limit the open sandy nesting areas favoured by Black-footed Albatrosses on some islands (e.g., Midway Atoll; Arata et al. 2009).
Collision with active fishing gear and vessel superstructure
Another source of fisheries-related incidental mortality for North Pacific albatrosses is collision with vessels' fishing gear (e.g., a trawler's third wire) or rigging. These collisions have been studied in the US for Short-tailed Albatross (Phoebastria albatrus) and were found to be low in part because of the low spatial overlap between albatross and bottom trawlers (Zador et al. 2008a, b); presumably this also occurs rarely in Canada for similar reasons. This low-level threat was not identified as being part of fisheries-related mortality in the species' status report (COSEWIC 2006).
Aircraft strikes kill a low number of Black-footed Albatrosses each year at Midway Atoll, a colony in the NWHI, but mitigation measures are in place to minimize mortality (COSEWIC 2006; Arata et al. 2009).
Introduced avian pox, spread by introduced mosquitos (Culex quinquifasciatus) at Midway Atoll and in the main Hawaiian Islands, is known to cause outbreaks in Black-footed Albatross chicks on rare occasions, though chicks generally survive. Whether the species is also vulnerable to West Nile Virus, avian influenza, and other emerging avian diseases is unknown.
Volcanic eruptions are also a recurrent threat where Black-footed Albatross nest on active volcanic islands (e.g., Torishima and San Benedicto Islands; COSEWIC 2006). Though the Black-footed Albatross undoubtedly evolved in the context of such catastrophic events, the combination of threats facing the species may leave them less resilient to periodic disasters.
Entanglement with active or derelict (lost) fishing gear
Outside of Canada, high seas and coastal driftnet fisheries were historically a significant source of mortality for Black-footed Albatross and other seabirds (Arata et al. 2009). Though high seas driftnet fisheries were banned by a United Nations General Assembly Resolution in 1992, both legal and illegal driftnet fishing effort still occurs, incurring an undocumented level of albatross bycatch (Arata et al. 2009). While there is no documentation of illegal driftnet fisheries occurring in Canada's EEZ, it is possible that Black-footed Albatross gets entangled with derelict (i.e., lost or abandoned) fishing gear (Birdlife International 2008).
Climate change and changes to foraging areas and food availability
In the Northeast Pacific, multi-decadal regime shifts (e.g., Pacific Decadal Oscillation) and shorter-term phenomena (e.g., El Niño Southern Oscillation (ENSO) and La Niña) cause system-wide oceanic changes that alter food supply. This results in reduced foraging success, either because there is less food or it becomes harder to locate. Reduced foraging success affects reproductive output of breeding seabirds, affects juvenile survival rates (Crick 2004; Kitaysky et al. 2006) and/or increases intervals between breeding years (Gilman and Freifeld 2003).
Collisions with wind farm turbines
Wind farms are an anticipated threat to Black-footed Albatrosses in BC as interest in ocean renewable energy increases, with the threat due to potential mortality from collisions and/or displacement of foraging habitat. Future marine wind farm projects, should they overlap significantly with albatrosses' at-sea distribution, pose a potential risk of collisions and displacement.
5. Management objective
The management objective for the Black-footed Albatross is:
- To help to increase global population numbers and maintain the population throughout its documented distribution in Canadian waters, by reducing at-sea mortality and otherwise augmenting international conservation efforts.
Since there are no breeding colonies for Black-footed Albatross within Canada, conservation of the Black-footed Albatross cannot succeed by Canadian management efforts alone; breeding populations and at-sea distributions span the North Pacific Ocean, thus requiring both international and national efforts to maintain and increase breeding populations. Within Canadian waters, reducing at-sea mortality is the primary contribution that can be made to overall population management.
This management objective is derived from the COSEWIC status report (2006) and more recent literature pertaining to this species. The international efforts, which implementation of this management plan will augment, are laid out in the United States Fish and Wildlife Service (USFWS) Conservation Action Plan for the Black-footed Albatross and Laysan Albatross (Naughton et al. 2007).
6. Broad Strategies and Conservation Measures
6.1. Actions Already Completed or Currently Underway
All of these management initiatives are an important contribution to the management of Black-footed Albatross and other at-risk seabird species in Canada, and should be continued or implemented.
6.2. Broad Strategies
The broad strategies (cf. Environment Canada 2008) that will be used to support management of Black-footed Albatross in Canada are:
- Develop and/or implement programs and policy aimed at threat reduction
- Identify and conserve habitat important to Black-footed Albatross
- Support research and monitoring to address knowledge gaps
- Increase education & awareness
- Continue international collaboration
Rationales for the broad strategies
The general rationale for utilizing these particular combined strategies lies in the need to address the interlocking social and environmental elements of the multiple threats that are occurring at both a national and a global level.
The Black-footed Albatross is the seabird most commonly caught by demersal longline fisheries in Pacific waters. The NPOA - Seabirds provides an existing framework for improving existing bycatch mitigation and enforcement of existing measures, and is built from within a Canadian legislative context (see Fisheries and Oceans 2007 for details). Implementation and monitoring of the recommendations within the NPOA - Seabirds will be an essential component of threat reduction for Black-footed Albatross.
It will be important to ensure that appropriate legislation and planning processes are successful in regulating the release of contaminants into the marine environment and consider the impacts of future marine industrial developments.
In the context of chronic oil spills it is important that existing oil spill deterrence programs are supported and appropriate legislative mechanisms are considered to reduce chronic oil discharge within areas important to Black-footed Albatross. In the context of catastrophic oil spills it is important that all appropriate legislative mechanisms are considered in order to minimize tanker traffic in areas important to Black-footed Albatross, and the development of coordinated spill response programs is encouraged.
Processes in support of the Oceans Act may be an important component of identifying and planning for managing and conserving Black-footed Albatross foraging habitats in Canada, including marine mapping or zoning to avoid or reduce spatial and temporal overlap between human activities and marine species such as Black-footed Albatross.
Additional research is required to address knowledge gaps related to the spatial-temporal distribution of Black-footed Albatross, the rate of bycatch mortality in longline fisheries, the effectiveness of bycatch mitigation measures, strategies for reducing overlap of longline fisheries and Black-footed Albatross habitat, the effects of plastic ingestion on Black-footed Albatross, and the evaluation of emerging threats. It is important that this information be used to inform ongoing and future management activities. Monitoring is required to measure changes in the abundance and distribution of Black-footed Albatross in Canadian waters in response to threat reduction measures.
Increasing public and industry awareness of actions and responsibilities that can reduce threats to Black-footed Albatross will help further the successful management of the species. Education and awareness should be prioritized for those involved in activities that contribute to any of the Canada-based threats mentioned in this management plan.
As indicated under the Management Objective (Section 5), Canadian goals and objectives will be supported by participation in ongoing international efforts to conserve and manage this species, e.g., the Agreement on the Conservation of Albatrosses and Petrels, and the Short-tailed Albatross Recovery Team (cf. USFWS 2008, Fisheries and Oceans 2012).

Priority reflects the degree to which the measure contributes directly to the conservation of the species or is an essential precursor to a measure that contributes to the conservation of the species. High priority measures are considered those most likely to have an immediate and/or direct influence on attaining the management objective for species. Medium priority measures may have a less immediate or less direct influence on reaching the management population and distribution objectives, but are still important for management of the population. Low priority recovery measures will likely have an indirect or gradual influence on reaching the management objectives, but are considered important contributions to the knowledge base and/or public involvement and acceptance of species.
7. Measuring progress
The performance indicators presented below provide a way to define and measure progress toward achieving the population and distribution objective. Every five years, success of recovery strategy implementation will be measured against the following performance indicators:
- At-sea mortality of Black-footed Albatross has been reduced in Canadian waters;
- The distribution of Black-footed Albatross in Canadian waters has been maintained; and
- International conservation efforts have been supported.

Appendix A: Effects on the environment and other species
A strategic environmental assessment (SEA) is conducted on all SARA recovery planning documents, in accordance with the Cabinet Directive on the Environmental Assessment of Policy, Plan and Program Proposals. The purpose of a SEA is to incorporate environmental considerations into the development of public policies, plans, and program proposals to support environmentally sound decision-making and to evaluate whether the outcomes of a recovery planning document could affect any component of the environment or achievement of any of the Federal Sustainable Development Strategy's (FSDS) goals and targets.
Recovery planning is intended to benefit species at risk and biodiversity in general. However, it is recognized that implementation of management plans may inadvertently lead to environmental effects beyond the intended benefits. The planning process based on national guidelines directly incorporates consideration of all environmental effects, with a particular focus on possible impacts upon non-target species or habitats. The results of the SEA are incorporated directly into the management plan itself, but are also summarized below in this statement.
This management plan will clearly benefit the environment by promoting the conservation of the Black-footed Albatross. The potential for the plan to inadvertently lead to adverse effects on other species within Canada was considered. The SEA concluded that this plan will clearly benefit the environment and will not entail any significant adverse effects. The reader should refer to the following sections of the document in particular: Needs of Black-footed Albatross; Description of Threats; Actions Already Completed or Underway; Broad Strategies and Conservation Measures.
Actions to reduce at-sea oiling, either chronic or catastrophic, will be beneficial for Cassin’s Auklets (Ptychoramphus aleuticus), Rhinoceros Auklets (Cerorhinca monocerata) and Marbled Murrelets (Brachyramphus marmoratus) which are all considered to be especially vulnerable to oil spills. Successful implementation of the NPOA - Seabirds in the Pacific region of Canada would also benefit Northern Fulmar (Fulmarus glacialis), Herring Gulls (Larus smithsonianus), Glaucous-winged Gulls(Larus glaucescens), and any other species prone to bycatch events.
Appendix B: Preliminary analysis of the Black-footed Albatross bycatch, Canadian West Coast Commercial Groundfish Hook and Line Fleet, 2006-2009
Prior to 2006, commercial groundfish fisheries on Canada's West Coast had variable levels of observer coverage. Beginning in 1996, the groundfish trawl fleet was subject to 100% at sea observer coverage. Starting in 1999, groundfish hook and line fisheries were required to have partial coverage of at-sea observers. Target levels of partial coverage varied among the hook and line fisheries but generally covered 10 to 15% of the fishing effort. Since 2006, all commercial groundfish vessels licensed to fish Canada's west coast waters must have on board either an independent at-sea observer or an Electronic Monitoring (EM) system. Most vessels in the groundfish hook and line fisheries now utilize the EM rather than at-sea observers; however, groundfish trawl vessels are still required to have 100% at sea observer coverage. As a condition of licensing, all vessels have to use seabird bycatch avoidance devices. After the completion of a fishing trip, a random audit of 10% of EM video imagery is carried out to verify catch. Seabird bycatch is recorded during those audits. For vessels carrying an at-sea observer, observers record seabird bycatch.
An analysis of Canadian west coast commercial groundfish hook and line fishing effort and associated seabird bycatch, 2006 through 2012, is currently in progress (K. Morgan, unpublished data). Bycatch data were obtained from vessel logbook entries and EM video audits. A small proportion of the seabird bycatch was reported to the species level; most were listed to the ‘group' level (e.g., unidentified albatross, unidentified gull) or simply as unidentified bird. Based upon the work of Smith and Morgan (2005), it was assumed that all albatrosses listed in the database were Black-footed Albatrosses. The following summarizes the unpublished analyses conducted by K. Morgan.
The annual total bycatch by fishery, gear type and year (2006 through 2012) in the longline halibut, sablefish, rockfish and spiny dogfish fisheries was estimated by extrapolating, from the percentage of sets audited to 100% of the sets that were fished, the number of birds detected in the EM audits. Over the 6-year period, the extrapolated average bycatch of albatrosses was 120 birds per year (range 0-269) for the above fisheries. As well, the extrapolated average bycatch of unidentified birds was 166 birds annually (range 35-376).
In addition to the bycatch events detected during the EM audits, 92 more albatrosses and 263 more unidentified birds were recorded in the vessel logbooks. The 6-year average annual number of albatrosses reported in the logbooks and not detected during the EM audits, was 13 birds (range 2-33), and that of unidentified birds was 36 birds (range 15-66). Because of the low occurrence of birds being detected in both the EM audits and reported in the vessel's logbooks, and because of the high number of unidentified birds, the predicted average annual bycatch of albatrosses (120) should be considered a conservative estimate.
To place the results of the above analyses in context, Wiese and Smith (2003) used a spatially and temporally explicit model to estimate that between 67 and 162 Black-footed Albatrosses were killed annually in the rockfish and halibut demersal longline fishery off Canada's west coast. They also noted that the mortality of Black-footed Albatrosses may have been as low as 22 or as high as 253 birds.
