If you’re going to sort through wild coho it’s sometimes a good idea to leave the bait at home. It can be tough to release fish on treble/stinger setups and they will eagerly take artificial. Small single hooks on spoons/hootchies help minimize mortality.
Agreed with Kelly.... Small hooks are key as well, larger hooks will eye hook and badly damage more fish. Also with all the shakers around minimizing damage is important. These little shakers (Coho and Chinook) have, in theory, survived the critical early mortality period after ocean entry. They are now heading out to sea and have a good chance of making it back to contribute to the fishery. They are valuable and should be treated with the same respect as an adult fish that needs to be released.
