My wife and I used to fish the straits (Neah Bay and Seiku) and had issues with the wild fish to hatchery ratios with damaged fish being released.We started using an item called a hoochie devil, made by scotty and then sold to the e-chip pro-troll folks who discontinued it. The point (no pun intended) is that it uses a single large 4/0 0r 5/0 siwash hook and the setup has a stop to controll where the hoochie is in relation to the hook. We had as many hook-ups and just as many came in as the traditional two hook set-up. A LOT less fish were deeply hooked, that trailing hook that can tear up gills or eyes isn't there, I've seen these single set-ups on commercial trollers as well. I can attest to the fact that single hooks are just as effective and a LOT less damaging to fish that must be released. There is an item being made now called a wiggle hoochie by shasta tackle, they are smaller but with the same lip and hoochie attached. John Keiser (salt patrol) uses them for blackmouth by swapping out the light leader and double hooks (they are made for kokanee) and using a single 2/0 to 4/0.He says they match the smaller bait. The hoochie devils are no longer available, Melanie and I bought out a lot of their remaining stock. The same single hook set-up can be done without this device by puttung a stop on leader above hook to keep the single point further down the hoochie and will kill less wild fish. With a flasher or dodger the hoochie has good action and slays the silvers in the straits while keeping our released wild stock safer. good luck, Bob R
