Various appellations have been bestowed on the mascalonge to denote its rapacity, as the shark, wolf, or tiger of the waters, all of which are well merited by that fierce marauder. It subsists entirely on fish, frogs, snakes, and even the young of aquatic mammals and water fowl. Nothing in the shape of food comes amiss to him. He is solitary in his habits, lying concealed among the water plants and rushes at the edges of the streams or channels and along the shores, or beside shelving rocks or banks in clear lakes, from whence he darts open-mouthed upon the luckless fish that approaches his lair. The number of fishes swallowed by a mascalonge during a single summer is almost incredible; and they are not minnows and small fry alone, such as are devoured by other predaceous fishes, but such as are old and large enough to reproduce their kind. It is fortunate that the mascalonge is comparatively a rare fish. As it is now being artificially propagated in some states, great care and judgment should be exercised as to the waters planted, so as not to jeopardize other and better game-fishes. It spawns early in the spring and in very shallow water, where most of the eggs are devoured by frogs, turtles, fishes, and water fowl--a wise provision of nature when it is considered that the female deposits from one hundred thousand to three hundred thousand eggs. The eggs are quite small, about ten or twelve to an inch, and hatch in about two weeks. The mascalonge is the most valuable food-fish of its family, and is pronounced by some as being really excellent; but I consider it much inferior to the whitefish, lake-trout, pike-perch, black-bass, or brook-trout. While possessing no especial flavor, its flesh is firm and flaky, more so than that of the pike or pickerel, and it commands a ready sale in the markets. It grows occasionally to an enormous size. I have taken it up to forty pounds, good weight. The late Judge Potter, of Toledo, Ohio, an angler of the old school, informed me that he had seen, in early days, many that weighed from fifty to seventy-five pounds. Mr. L.H. McCormick, formerly of Oberlin College, Ohio, saw one taken in a pound net that weighed seventy-two pounds. The late Dr. Elisha Sterling, formerly of Cleveland. Ohio, a contemporary of Judge Potter and the late Dr. Garlick, the father of artificial fish-culture in America, told me of one he once speared in Lake Erie that weighed eighty pounds, and said that those of fifty to sixty pounds were common in the forties.
