I have been taking an exceptionally interesting course with one of the authors of that report on sea lice at the University of Victoria, and he has provided us with a number of frightening insights on salmon farming in BC. The anti-biotics and other chemicals used to control the populations of parasites like the sea lice, are as already mentioned, bad for the environment, and bad for stocks of wild salmon. It has been suggested that the salmon be raised in the closed pens, the techonology already exists, although the industry claims the costs are prohibitive. Unfortunately, even if this step were to be taken, it in no way makes salmon farming a sustainable practice. Raising farmed salmon requires huge inputs of fish protein (a weight ratio of about 3 to 1) that has to come from wild stocks somewhere else in the world. In the case of BC's salmon farms it comes from the Chilean anchovy fisheries and other fish well down food chain that support their local ecosystem and their fragile economy. Scientists have estimated that some of the Chilean fisheries will collapse in a similar patter to our Cod fishery within the next 8 years. What will the BC salmon farmers do then? Exploit another third world fishing economy? Not all aquaculture is bad, however some species require a great deal of protein input to create the output we all desire. There are some species, like carp and tilapia that are incredibly efficient and require very little inputs compared to farmed salmon. Hopefully some chef can write an overpriced cookbook and make Tilapia sexy...
