Canadian supermarkets are continuing to stock their fish counters with threatened ocean species, according to a Greenpeace report released Tuesday.

Greenpeace said the grocery chains Loblaw and Sobeys sell all of the 15 species included on the environmental group's Redlist, a list of fish the group suggests are at risk of being overharvested or raised using non-environmentally friendly methods.

Loblaw declined to comment on the report.

Greenpeace acknowledged that Wal-Mart, Overwaitea and the Thrifty Division of Sobeys have started to consider sustainable seafood purchasing strategies.

Concerns about overharvesting and unsustainable fishing methods have been raised by many environmental groups in recent years, including the Living Oceans Society, the David Suzuki Foundation and the Ecological Action Centre.

In May, one of Vancouver's most popular restaurants, C restaurant, said it was considering taking wild salmon off the menu as sockeye salmon runs reached record lows.

The report also suggested grocery stores are failing to provide consumers with information on fish stock status and fishing methods. Nearly seven out of 10 Canadians are confused about sustainable seafood options at the grocery story, according to a survey commissioned by Greenpeace.

The national survey, conducted by Léger Marketing, was conducted between May 21 and May 25 and included 1,508 respondents. The margin of error is +/- 2.52 per cent, 19 times out of 20.
