The only way to promote sustainable fishing in the wild is to practice catch and release. No matter how good the fish tastes. No matter what the mirror on the wall tells you. Even when eating a particular type of fish makes your skin smoother, turn your skin fairer, increases your libido and what not. If it’s fishing we like, then fish for fun. If it’s eating fish that’s the priority then it’s easier to get the fish from the market.
Stop preaching and bitching. Just do it!
