Ok, I catch a 500lb Blue Fin Tuna, eat 5oz. The fish is dead, and I'd say it was over fishing for 5oz.

I didn't even have to think about it. What, exactly, is one to do with what is left? How does one buy only 5 oz? Silly! I get that they want us reduce the amount we're buying/killing, but a better way to say it must exist? Surely.

Maybe they were referring to fish fillets? That whole tuna could be filleted so that the individual servings are smaller.

5 ounces? Whatever happened to the 4 ounce serving?

3 ounces of meat are suggested for portion size, it's all we need. So go figure, even those estimates are high. Admittedly, two servings a day. The size of a deck of cards. Not a lot.

Here is a link that might be useful: FDA suggested servings pyramid

hmmm, I guess I missed the point. If you buy a WHOLE fish, why eat only 5oz? It's dead, it's already been caught. How would it be good for the ocean just to eat 5oz of it?

I don't know abou you, but I either buy a whole fish like a trout or other pan fish, or I get whatever the butcher has already cut off the big DEAD fish, like tuna.

I'm betting that from a money-wise stand point, he has already planned to cut as many potions from that big fish as possible.

That's certainly how I took it. Unless, we're supposed to lop off only what we "need" and set him free again? Seems impossible to me!

Speaking of lopping off what you need..I was listening to a program on NPR a couple of days ago about sharks. Did you know that 93 million of them are killed each year for their fins? I found that really hard to believe but it's true. I guess shark fin soup is a delicacy and a sign of wealth in several eastern countries. What they do is cut off the fins and then throw the bodies back into the ocean.
