B.C.’s Fishing Industry

1) Choose a species of fish and explain which ones you should consume and which ones you should avoid.

Sockeye Salmon (my favourite)

Based on the information I got from Ocean Wise, I found that the species Gillnet, Purse Seine, and Troll that are caught in the USA: Washington, Oregon and California should be avoided. In the fisheries in these areas, the farmed salmon are supplemented with hatchery fish which get to intermingle with the wild variety. When this happens the fishermen can accidentally catch the wild fish, which are an endangered species. Therefore, to prevent the extinction of the endangered species of that area, those fish should be boycotted.

2) With reference to the video “Salmon Confidential” and your own research about the advantages and disadvantages of salmon farming, assess how sustainable aquaculture is.

When fish are farmed (aquaculture), the close quarters of the fish allow for the rapid transmission and mutation of fish diseases. These fish are farmed in pens that are able to interact with the wild fish, and thereby, transmit the diseases that are produced to the wild variety, which kills most of the wild fish. If this continues It could kill all of our fish: farmed, and wild, therefore, I would say that aquaculture is not sustainable. The advantage of aquaculture is that it gives fish farmers a guaranteed “harvest” and they are able to control which variety the get, wile “protecting” wild populations. I think the way to make aquaculture sustainable is to only raise the fish to a young age and then release them into nature to go out into the ocean and come back to spawn. That way the fish are able to be more dispersed and have a much reduced chance of getting diseased. When the fish come back to spawn, the fisheries can just catch them with a large net, prepare some for consumption, and let others spawn for them to raise. This way we let nature do most of the work for us and we put more fish back into the ecosystem.

One thought on “B.C.’s Fishing Industry

  1. Gillnet, purse seine and troll are ways to harvest the fish. Those from the northwest USA seem to be ones not recommended. It looks like all the other types of sockeye are fine.

    So it sounds like you would recommend more hatcheries. But I suppose as a business, it’s a big risk to do so and who knows who’s fish you’ll be catching.
