Interesting discussion. I guess it all boils down to whether it is currently illegal or unethical to target coho for C&R when an area is closed to rentention of salmon. As I read the regs, it doesn't appear to be illegal as long as you don't retain fish. Whether or not it is ethical isn't something as easily determined. I don't see a need to judge those who have concluded that this falls within the range acceptable angling behavior. That's a slippery slope. It is also legal to intentionally kill 2 wild chinook caught from public fishing piers during the closure. Is that ethical?
