I fish...When I got to Alaska I keep the grayling and release everything else, rainbow trout are too beautiful to eat!
In the Sea of Cortez I keep only the occasional Bonito or sea bass...I don't need to keep 50 pound Dorado and end up throwing 90% of it away.
Quite sad to see how corrupt the fishing industry on the Sea of Cortez is...people bringing fishing trawlers taking thousands of Dorado, Tuna and Marlin when the limits are waaay lower, even with a 50,000 dollar commercial permits. And I doubt these guys have permits, either.
Sea of Cortez is a must visit place for anyone who loves fish and the ocean. The reefs are pretty intact, but I see less whale sharks and marlin every time I go.
