While in Bankok in the sixties I ate sharkfin soup, fried sea turtle, various pate's of porpoise and other sea creatures many times. It was cheap eating at the time. Those people didn't think a thing of it then and probably don't now. It's called suvival. I doubt that the fishermen got much for their catch in those days and I would suspect that the entire shark, turtle , dolphin, etc. was comsumed. The problem now is that people in modern times are dumb enough to pay lots of bucks for bragging rights that they have paid many hundreds of dollars for a bowl of hot water with a half ounce of sharkfin and some seasonings. I have a friend who is like that. He never can get over telling people about this sort of thing he has done in the past. Sort of like the $2000 bottle of wine that people brag about comsuming. It's an ego trip that I will never understand. I would think that a person would brag if they got the soup or wine for a dollar instead. Of course, I am a cheapskate with very low self esteem and no ego.
