ItsBruce:Trout: Does not taste too good raw.
Shark: They will eat anything and apparently, that gets into their flesh.
One other warning: If you go out on the half-day fishing boat, don't sample the bait or the catch -- it really upsets those around you to see you sampling the bait. (Don't ask how I know.)
Very interesting. Trout and other fish flesh can carry a variety of parasites. I have often seen nematodes parasites wriggle out of the flesh. Ick.
Sharks need to have the flesh purged of nitrogenous waste. That's why a soaking in water or milk overnight is often recommended by chefs. Eating it straight out of the water would probably not be advisable.
I once ate the flesh of a 15 foot Sleeper Shark and it tasted great - after a night of soaking and deep fat frying. Blue shark fresh off the boat - phoeey. Come to think of it I have never seen shark sushi, or sashimi? X
