Implications of aquaculture for wild fisheries: the case of Alaska wild salmon
Worldwide aquaculture production is growing salmon suggests that aquaculture may have significant and wide-ranging potential implications for wild fisheries. Salmon farming exposed wild salmons natural monopoly to competition, expanding supply and driving down prices. Wild salmon has faced both inherent as well as self-inflicted challenges in competing with farmed salmon. The economic pressures caused by competition from farmed salmon have been painful and difficult for the wild salmon industry, fishermen and communities, but these pressures have contributed to changes that have helped make the salmon industry more economically viable. Farmed salmon has greatly expanded the market and created new market opportunities for wild salmon. Farmed salmon has enefited consumers by lowering prices, expanding supply,developing new products and improving quality of both farmed and wild salmon. Salmon farming has had no apparent direct effects on Alaska wild salmon resources, but could have indirect effects on wild salmon resources that might be positive or negative The experience of Alaska wild salmon suggests that anyone interested in wild fisheries should pay close attention to what is happening in aquaculture. No wild fishery market -especially for higher-valued species-should be taken for granted.
