Re: accidental catch...
Yes the Buffalo is an official fish:
[B]Bigmouth buffalo, Ictiobus cyprinellus
Ictiobus, also known as buffalo fish, is a genus of freshwater fish common in the United States, but also found in Canada, Mexico and Guatemala. It is sometimes mistaken for carp because of its flat face and large, silver scales running along the body, though it lacks the whisker-like mouth appendages common to carp. Buffalo fish live in most types of freshwater bodies where panfish are found, such as ponds, creeks, rivers, and lakes. Ictiobus was caught by the Lewis and Clark Expedition.
From a fishermen's point of view, however, [B]the buffalo fish is not a popular game fish because it is difficult to catch. Yet, once on the line, it can put up a good fight.[/B] The preferred method of catch is by the use of gill nets. These nets are set by hand during the night where it is most effective(tmz). It is an affordable fish that is popular in the southern U.S. including the Memphis and St. Louis markets.
