My uncle is a 35 year service fish bio in S. E. alaska,he knows everything there is to know about fish,he told me a steel finewire hook like the old mustad 9263's are gone in about 24-30 hours,the combo of the salt water and the enzymes in the fish cause rapid decay of the metal through electrolisis,depending on the salinity of the water.Even stainless hooks will get ate into as well with time and it aint much time either as the hooks are of 304 high carbon content stainless.
If this state makes the commercials throw dead or dying by catch purse seined non target salmon over the side,your going to have a hard time talking yourself out of a ticket.My commercial fisherman buddy was totally ticked off at the states cockamamie rule on that last august when they got a big school of 20-40 pound kings in the bag with a couple thousand pounds of pinks.They have a recovery box on board but he said the bigger fish do not respond well to it and almost always end up going back over the side dead.Total waste that could be used to feed the less fortunate and down on their luck.
