Nutria meat really is quite delicious, not unlike a suckling. Many Farmers in the European countries continued raising small numbers of Nutria after the market for Nutria fur went down, just for their meat.
It's a shame the greater American economy and society doesn't take advantage of these types of animal overpopulation. Modern research warns us about the dangers of desertification, corn products (including corn-fed livestock), etc., so what better way to feed people than to trap and process a destructive population of nutria that will feed in the wild whether they are trapped or not? California, among other states, has a similar problem with deer. With the prices of many meats in the US supposed to increase this fall due to drought, I sure would snatch up nutria or deer meat at half the price of beef if I had the chance if they were available--although nutria are ugly buggers; then again, a cow isn't much of a looker either.
