Extinction Risk

There have been widespread concerns about the impacts of fisheries on targeted species as well as species that are caught incidentally. Many fish populations have declined by more than 90% in only a few decades, leading to concerns about extinction threats. We are testing hypotheses for the biological bases of vulnerability, based on life histories and behaviour, and applying our findings towards improvements in the way in which the threatened status of fishes is assessed.

The findings on life history correlates of extinction risk are being used to inform threat criteria used by the Canadian committee that determines the threat status of plants and animals (COSEWIC) as well as the international criteria used by the IUCN Red List.
