Recovery Strategy for the Atlantic Whitefish (Coregonus huntsmani) in Canada (Final)


Appendix II – Schedule of Studies to Identify Critical Habitat

In the absence of sufficient, long-term studies on habitat use to identify the critical habitat of Atlantic whitefish within this recovery strategy, SARA requires under section 41 (1c.1) that a 'Schedule of Studies' be prepared. The following research activities in Table 2 target key knowledge gaps on the habitat requirements of this species. Accompanying each activity is an assessment of the overall priority (recovery or survival), potential partners, and estimated timing. It is hoped the implementation of the following schedule will yield information that will allow for the description of critical habitat for this species. It is important to note that activities outlined in this schedule are subject to priorities and budgetary constraints of the participating jurisdictions and organizations. Consequently, these activities may not necessarily be completed within the timelines established below. It should also be noted that it may be possible to designate critical habitat under Section 58 of SARA before the end of the timeline indicated in Table 2.

Re-evaluate the spatial and temporal distribution of Atlantic whitefish in the Petite Rivière watershed for all life history stages:
- the population within the 3 lakes (Minamkeak, Hebb and Milipsigate)
- the anadromous component contingent on the provision for fish passage
Bathymetrically map the 3 lakes to identify and delineate potential critical habitat

Conduct radio telemetry studies to identify:
- seasonal foraging areas
- thermal refugia
- spawning habitat
- rearing habitat
- seasonal migration (both landlocked and anadromous forms)
