It is one of the most voracious of our fishes, feeding upon all forms of small fry and insects, and where abundant is very destructive to the more valuable forms of fish life. Its flesh is said to be soft, nauseous and quite uneatable.

Early in June, when about to spawn, the Catfishes select a spot in quiet, shallow water near aquatic weeds, and there they make a nest, from eight inches to one foot in diameter, by clearing out a slight depression in the mud or sand. In this nest about two thousand eggs are deposited, over
