Re: Catch and release or catch and eat?
I'm generally a catch and release fisherman but I agree with Frank, it really depends on the fishery. I don't believe there is anything wrong at all with keeping a few to eat, as long as it's with in the law.
Weather hunting or fishing you should never kill more than you're going to use and that doesn't mean packing the freezer either. The good eating fish are generally in the mid sizes for the species, that's also usually where the population numbers are as well.
Definitely let the trophies and the dinks go. You can always measure and photograph the trophies thoroughly for a replica to be made.
