The earlier post Death Fish discussed the harmful fat profile of farmed fishes, especially tilapia and catfish, due to their diets of grain. This problem may cure itself.

Catfish farmers across the South, unable to cope with the soaring cost of corn and soybean feed, are draining their ponds.

“It’s a dead business,” said John Dillard, who pioneered the commercial farming of catfish in the late 1960s. Last year Dillard & Company raised 11 million fish. Next year it will raise none.

Some intend to fill their ponds and grow maize and soya since it is more profitable than growing fish that eat maize and soya.

People can eat imported fish, Mr. Dillard said, just as they use imported oil. . .

The industry’s decline accelerated when producers from Vietnam and China flooded the domestic market, putting a ceiling on prices. . .

last summer when the Food and Drug Administration announced broader import controls on Chinese seafood, including catfish, saying tests had shown the fish were contaminated with antimicrobial agents.

Well, maybe the problem doesn't cure itself then. Now we can have fish with an unhealthful fat profile and various contaminants as well.
