This is one reason why the European Union should aspire to a policy on salmon that keeps as close to nature as possible, although salmon farms will of course still be needed for the production of both rainbow trout and salmon.

In order to increase the level of protection as regards introduction of fish into the area covered by the programme, live trout and other fish destined to restaurants for direct consumption as well as rainbow trout intended for introduction into certain artificial lakes or fish water, must come from farms or areas recognised as free of VHS and IHN.

Freshwater aquaculture chiefly involves trout farming (the main species produced in terms of value, with EUR 500 million), the chief producers being France, Italy, Germany (carp) and Denmark.

These parasites proliferate on farmed salmon, and the young wild fish of migratory species (mainly of sea trout) could be heavily infected during their estuarine movements.

Trout farming in the past had viability problems almost everywhere in the Union, in recent times the situation has slightly improved.

Q-54 — Mr. Robinson (Burnaby—Douglas) — With regard to Canadian Food Inspection Agency (CFIA) survey tests of domestic and imported aquaculture fish: (a) what drugs, chemicals, contaminants and pesticides were included in these tests; (b) what are the tolerance levels for these compounds under current Canadian regulations; (c) when were these tolerance levels last updated; (d) what scientific research has been conducted on potential impacts from PCBs since these tolerance levels were first established; (e) what is the number of fish tested annually in CFIA surveys; (f) what is the percentage of imported fish tested in these surveys; (g) what percentage of Chilean farmed salmon imports is tested for malachite green; (h) what percentag ...[+++]e of Chilean farmed salmon has tested positive for malachite green; (i) what is the percentage of fish tested in relation to the amount imported/exported; (j) what are the Canadian standards for allowable residues of malachite green; (k) what percentage of Canadian farmed salmon and trout is tested for malachite green; (l) what are the Canadian standards for antibiotic residues in farmed fish; (m) what percentage of Canadian farmed salmon is tested for antibiotic residues; (n) how many times has the CFIA recalled farmed fish because of elevated levels of antibiotic residues; (o) what are the Canadian standards for levels of the therapeutant emamectin benzoate in farmed fish; and (p) what percentage of Canadian farmed fish is tested for emamectin benzoate?
