As instances of new waters in which its increase was rapid, the Delaware, Susquehanna and Potomac Rivers may be mentioned. In 1854 thirty small-mouth bass, about six inches long, were taken from a creek near Wheeling, W. Va., and placed in the Potomac near Cumberland, Md. From this small plant the entire river above the Great Falls, and all its tributaries, became well stocked, and has afforded fine fishing for years.

Commercial Fishing

In former years the black bass was quite an important commercial fish in the Middle West, but since the enactment of laws prohibiting seining and net-fishing of streams it is not often seen in the markets, and then it is mostly from private ponds. In the States of Washington and Utah, however, where it was planted in some rather large lakes years ago, the markets are pretty well supplied with this delicious fish, for, barring the lake whitefish, it is the best food-fish of fresh waters. Owing to the well known improvidence of market fishermen it would be well to prohibit its sale entirely in all sections of the country when taken from public waters.

Propagation

Owing to the desirability of the black bass for stocking waters, the demand for both private and public streams and ponds is far in excess of the supply. Undoubtedly the best plan for stocking is that of planting adult fish, as already alluded to. But owing to the difficulty of obtaining adult fish, the energies of fish culturists have for years been directed to a solution of the question of supply. So far, however, their efforts have been but partially successful.

Character of Eggs

The eggs of the salmon, trout, grayling, shad, whitefish, etc., can be stripped from the fish, can be separated and manipulated as easily as so much shot, and made to respond readily to fish-cultural methods. But the eggs of the black bass are enveloped in a gelatinous mass that precludes stripping, and their separation is extremely difficult, if not impossible. Consequently any attempt at their incubation by the usual hatchery methods would prove futile.

Pond Culture

The only feasible and successful plan is that of pond culture. Of this there are several methods. One either allows the bass to proceed with their parental cares in a natural manner; or early separates the parent fish from the young fry, which are then fed and reared to the desired age for planting. The United States Bureau of Fisheries and several of the individual states pursue this plan, and supply the fry to applicants free of charge.
