Sockeye salmon The conservation status of sockeye populations in Canada is under review by Fisheries and Oceans Canada as part of its Wild Salmon Policy strategy to standardize monitoring of wild salmon status. Salmon runs of particular note are the Skeena and Nass river runs, and the most famous is the Fraser River sockeye run. The Fraser River salmon run has experienced declines in productivity since the 1990s, mirroring a similar decline in the 1960s. The return abundance (population) of Fraser River sockeye in 2009 was estimated at a very low 1,370,000, 13% of the pre-season forecast of 10,488,000. That represented a
Pain in fish birds, frogs, salamander, reptiles, fish, and crustaceans. A recent article by Howard Browman and colleagues provides an overview of what different perspectives regarding fish pain and welfare mean to in the context of aquaculture, commercial fisheries, recreational fisheries, and research. It has been argued that fish can not feel pain because they do not have a sufficient density of appropriate nerve fibres. A typical human cutaneous nerve contains 83% GroupC nerve fibres, however, the same nerves in humans with congenital insensitivity to pain have only 24–28% C-type fibres. Based on this, James Rose, from the University of Wyoming, has argued
