Pelagic fish in Canada
Norwegian public radio (Google-translated) reports on the instant dead of thousands of fish in a bay in the island of Lovund, Norway. An air temperature of -7.8 C (17.96 F) combined with a strong east wind froze the sea water instantly, trapping and killing the fish you can see in this fishapocalyptic image:
The dog owner says that he has never seen such a phenomenon. NRK claims that the herrings were chased by cormorants into the bay when the deadly freezing happened. Aril Slotte—the head of pelagic fish department at Norway's Institute of Marine Research—says it is not uncommon for herring to get very near the shore when chased by predators, sometimes getting trapped by the low tide in areas like this bay.

It's an issue with most freshwater fish if you2008-01-21 12:10:09 by compare_them_with
Ocean fish...even predatory FW fish eat other stuff that bottom feeds and they pick up that flavor, while pelagic predatory fish like tuna eat other smaller fish and crustaceans that feed on krill and plankton.
Part of the issue with tilapia is that unlike other fish they tolerate extreme conditions of poor water quality...they are so tough they can live in fresh OR saltwater and anything in between...so it's easier for people who don't care about water quality to actually get them to market, where other fish would just die from neglect....but when raised properly they are pretty mild and aren't any muddier tasting than other FW fish that live in still waters.
