Also, few of our rivers will sustain a wild fish population unless they
are
catch and release...and patrolled!! Again, the game wardens will nly
patrol
areas where there is a largae population of fishermen!

Well, you could find more ROFF posts on this matter than you'd care to
read if you googled it, but we'd probably all agree that few of our
rivers will sustain a fishably healthy wild fish population unless
fish mortality caused by fishermen is tightly controlled. C+R is most
definitely NOT the only way to achieve that.

As for sustaining an arbitrary wild fish population, I once spoke
to a trout researcher who surveyed quite a few streams in Mexico,
and he stated that he did not believe it was possible to exterminate
a wild population merely by hook+line fishing. Down there he did
see fishing, even flyfished with the local 3-person flyfishing club,
and any fish caught was _always_ kept. Yes, the trout populations
were very low. Yes, the fish were very small. But they were there.

Lots of experts throughout history were certain that [insert critter of
choice here] could not possibly exterminated by means of [insert method of
choice here]. They were wrong. Always. Evidently, some things don't
change.
