Salmon, after identifying as legal (no adipose fin at times of year) we net, bonk on board, tie to rope and then slice gills off the swim deck off the stern while wearing fillet glove. With the Columbia running 73 degrees in August, it is important to transfer them to a large cooler with ice (I use gallon milk jugs to keep it dry - we figured out water ruins more in a cooler than warmth does a long time ago). For halibut we use the harpoon or the .44 mag Ruger - which also gets them bleeding; I like the #8 shotshell rounds at close range, the 300 gr. Noslers are just too loud. Tip of the day... don't shoot them in your boat. One thing worth mentioning, use a fillet glove.... they are stainless steel and kevlar, provide an excellent grip on the slimey catch and protect the hand from accidental slices while out bobbing around in the waves where a cut artery could be extremely unfortunate, especially if by yourself. Wear it on the left and hold the knife firmly with the right. Extra long (5"?) headed needle nosed pliers are great to have too for reaching deep hooks, don't know how I got by so long without them. For tuna we use a large garbage can loaded with iced salt water, cut their gills and drop them in head first, letting them flail away there so we can keep trolling. Once the action slows we pull them and put them in iced fish bags. Foodsaver vacuum sealers are wonderful.... we use it for salmon, preserving bait, home grown hogs, deer, elk and the bulk packed meats from the store. C.W.
