Sockeyes after they make the transition to fresh water are very durable, scales are set, and that thing about a light tap on the head killing them is not a problem anymore which all in all makes them an excellent target for a two fish limit and a C&R fishery. However targeting King salmon in the salt chuck for C&R is pretty questionable and I can guarantee you that if it grows it will result in a total closure of all salt water angling so if you do that sort of thing it is incumbent on your part to keep it under your lid. There are numerous studies and loads of antecdotal info showing morts from 30 to 50 percent on chionook in the salt from both sport and commercial. We all need to be aware of our impact on these finny critters were chasing give em a break a couple of fish will make you smile just as much as a bunch if you make it more difficult to catch them.
