Tiki with a gun sounds almost as dangerous as Hoffman without a gun.
As to what fish to eat or not: I long ago stopped eating swordfish, tuna (sometimes make a salad of canned tuna), Orange Roughie
(wasn't great eating anyway), Chilean Sea Bass (mild to the point of boring), any variety of shark, codfish (god, I miss that fish), and a few others that don't immediately come to mind.
That still leaves me with a world of great fish to eat - black Sea Bass (Tautog), trout and salmon, oysters, clams, scallops,hake, pollack, shrimp (Gulf, wild caught), bluefish, striped bass, lobster, crab, anchovies, sardines... Shall I go on?
My point is, there is no need for us to continue eating fish that are in danger of disappearing entirely. If we stop eating them for a while, they'll come back, and we can enjoy them in moderation forever after.
