Changes to fisheries legislation have removed habitat protection for most fish species in Canada
Date:11/7/2013

Federal government changes to Canada's fisheries legislation "have eviscerated" the ability to protect habitat for most of the country's fish species, scientists at the University of Calgary and Dalhousie University say in a new study.

The changes were "politically motivated," unsupported by scientific advice contrary to government policy and are inconsistent with ecosystem-based management, fisheries biologists John Post and Jeffrey Hutchings say.

Their comprehensive assessment, in a peer-reviewed paper titled "Gutting Canada's Fisheries Act: No Fishery, No Fish Habitat Protection," is published in the November edition of Fisheries, a journal of the 10,000-member American Fisheries Society.

"The biggest change is that habitat protection has been removed for all species other than those that have direct economic or cultural interests, through recreational, commercial and Aboriginal fisheries," says Post, professor of biological sciences at the University of Calgary.

Before, "there used to be a blanket habitat protection for all fish species," he says. "Now there's a projection just for species of economic importance which, from an ecological standpoint, makes no sense."

Studies cited by Post and Hutchings show that not protecting habitat is the "single greatest factor" for the decline and loss of commercial and non-commercial species on land and in water.

Yet the changes to the Fisheries Act removed the "mandated legal protection" of habitat even for fish species that are in decline, Post says.

About three-quarters of approximately 80 freshwater fish species in Canada listed as being at risk, threatened or endangered "are not going to receive the protection that they did in the past," Post says.

Hutchings is a former chair of the Committee on the Status of Endangered Wildlife in Canada while Post is a current member. Both scientists' research is supported by the Natural Sciences a
