Legal Listing of Aquatic Species

3.5 Speckled Dace (Rhinichthys osculus) Status: Endangered Last Examination by COSEWIC: November 2002

Where the species is found and biology:

In British Columbia, speckled dace occur at elevations below 985 m and are restricted to a 112 km section of the Kettle and
Granby Rivers (part of the Columbia River system). Speckled Dace prefer stony habitat where there are hiding spaces
between stones washed by moderate current. The few adults taken from B.C. were found under larger stones or
overhanging banks where the current was moderate. The details of the species' reproductive behaviour are unknown.

COSEWIC Reason for Designation:

Speckled Dace have a very restricted Canadian range where they are subject to deteriorating water quality as a result of
urban and industrial development, as well as to loss of preferred habitat and fragmentation due to construction of a proposed dam.

Potential Protective Measures and Impacts:

There are currently no planned measures as a result of automatic prohibitions. However, over the longer term, recovery planning may result in management measures and identification of critical habitat that may impact individuals, businesses, and governments.

Examples of potential protective measures may include:

  • Measures to change land and water use activities - These range from the activities of individuals (i.e. gardening, hobby farming, recreation, etc.) to those of commercial entities (i.e. industrial forestry, urban development, farming and ranching, etc.).
  • Measures to control water quality and timing of water flowing into tributaries, aquifers, lakes and rivers.

It should be noted that management measures will be developed through the recovery planning process and implemented after further consultation.

3.6 Salish Sucker (Catostomus sp.) Status: Endangered Last Examination by COSEWIC: November 2002

Where the species is found and biology:

In British Columbia the Salish Sucker is found in the headwaters of small streams. The population is restricted to the southwest part of the province. Salish Suckers spawn in the early spring in areas of fine gravel.

COSEWIC Reason for Designation:

The Salish Sucker has a very restricted Canadian range within which populations are in decline as a result of habitat loss and
degradation resulting from urban, agriculture, and industrial development.

Potential Protective Measures and Impacts:

There are currently no planned measures as a result of automatic prohibitions. However, over the longer term, recovery planning may result in management measures and identification of critical habitat that may impact individuals, businesses, and governments.

Examples of potential protective measures may include:

  • Measures to change land and water use activities -- These range from the activities of individuals (i.e. gardening, hobby farming, recreation, etc.) to those of commercial entities (i.e. industrial forestry, urban development, farming and ranching, etc.).
  • Measures to control water quality and timing of water flowing into tributaries, aquifers, lakes and rivers.

It should be noted that management measures will be developed through the recovery planning process and implemented after further consultation.
