Australian mud oyster (Ostrea angasi) and Chilean flat oyster

Q-97 — Mr. Stoffer (Sackville Musquodoboit Valley Eastern Shore) — In regard to the Tulsequah Chief Mine project: (a) which of the seventy stream crossings, sixty-four culverts and seven bridges to be undertaken in association with the proposed project pose the highest risks to the spawning or rearing habitats of chinook, sockeye, coho, pink, chum salmon, and to the water quality in the area; (b) which of the proposed undertakings pose the greatest risk to other fish species in the area such as Dolly Varden char and whitefish, and cutthroat, bull and steelhead trout; (c) what are the estimated costs to pump back and treat the metals tailing seepage entering the Shazah wetland as a result of the project operations; (d) what are the concer ...[+++]ns of the Department of Fisheries and Oceans related to post-closure issues and road issues including fish passage at crossings, sediment release from the road, the status of roads post-closure, habitat displacement at causeways, and the geotechnical stability of the road; (e) does the government acknowledge and support requests from the community, fishermen associations, NGOs, and the State of Alaska for the project to be referred to the Pacific Salmon Commission for study and recommendations, and if not, why not; (f) will government approval for the project constitute a breach of the " safe passage" provision in the Pacific Salmon Treaty, and if not, why not; (g) what is the government's methodology for the calculation of reclamation bonding to limit taxpayer liability given the mine's remote location and acid mine drainage risks to critical fish habitat; and (h) why has the site never been reclaimed and acid drainage from the mine, identified by Environment Canada in 1995 as acutely toxic to fish, been allowed to continue to flow into the Tulsequah River?

9. Takes the view that fishing techniques for demersal species should be examined carefully and in detail in order to identify the non- or least detrimental species for the seabed; stresses that appropriate use of fishing techniques for demersal stocks is of great importance in preventing the growth of excessive populations of veined rapa whelk (Rapana venosa), which threaten the natural filter represented by the seawater blue mussel (Mythilus galloprovincialis), the stripped venus clam (Chamelea gallina), noble oyster (Ostrea edulis) populations and many other shellfish;

Non-native or alien species, such as rainbow trout or Pacific oyster, have played a crucial role in the rapid growth of the European aquaculture industry.

([46]) For example, in the southwest Atlantic on Argentina’s Patagonian shelf (hake and squid); on the Challenger plateau in the high seas off New Zealand (orange roughy); in the South Pacific (tuna, dolphin, and shark); in the east-central and southeast Pacific off Chile and Peru (blue whiting and jack mackerel); in the “Doughnut Hole” in the Central Bering Sea and in the “Peanut Hole” in the centre of the Sea of Okhotsk off Russia’s Pacific coast (pollock); in the Barents Sea “Loop Hole” off the coast of Norway (cod); and in t ...[+++]he “Doughnut Holes” of the Northeast Atlantic (herring and salmon).

Approximately 90 per cent of our production is represented by Pacific oysters, which are sold live in the shell or processed into fresh shucked meats and frozen product forms.
