The Sea Bass, which is of the same order and family, _Pereidæ_, is purely a sea fish, never entering estuaries or rivers, and never being taken in other than salt waters, on the outer bars and sea-banks, whereas the Striped Bass, like the Salmon, though salt water is necessary to him, in order to give vigor to his constitution, and perhaps to enable him to reproduce his species, is taken without distinction in the clear cold spring-waters of the river-heads, in the brackish slack-waters of the broad estuaries, in the strong, whirling salt eddies of sea-channels, such as Hellgate, and the inlets from the ocean to the inner bays, and lastly in the tumbling and flashing surfs on all the outer beaches, from those, I believe, of Hatterns, alone all the coasts north-eastward to those of Jersey and Long Island; on which they are taken with the squid and the seine from July to November, of rare excellence, and in great abundance. The river runs of the Striped Bass are very singular, and though I will not say unaccountable—by no means accounted for. So soon as the Smelt, Shad, and Herring enter the river-mouths and estuaries, the Striped Bass is found following them; and in every different water it appears that he acts on a peculiar and instinctive principle. Where, when, or how he spawns no man knows or has written. Our rivers he enters from the Delaware eastward from the first of March and later as the season offers, and makes up to the clear, cool spring-waters of the rivers near their heads. At that time he may be fished for, in the Delaware and in all the rivers in which the Shad run up and spawn, with _shad-roe_ FATALLY. In waters up which the Shad does not run this bait is useless. Thus, for instance, at Macomb’s Dam, Kingsbridge, and all the Harlæm River and Hellgate, in the neighborhood of New York, shad-roe is _useless_; because the Shad do not spawn there, and the Bass _know_ it. While in the Passaic, at Belleville Bridge and Acquanonck, up to both which places these fish run, there is a certainty of taking them with this bait, because Shad do spawn in the Passaic. Therefore, in all rivers up which Shad run, the true and best bait for the Striped Bass is the shad-roe. This must be prepared thus. The roe of the female fish—that is the _hard_ roe—must be taken, cleaned, washed, and washed again, and then potted down with two ounces of salt to every half pound of roe, pressed close into a stone pot and hermetically sealed. After three months it will be fit for use; when it must be cut out of the pot like cheese, fastened on the hook in a small lump, and tied to it by a lapping of light-colored floss silk, or raveled hemp.
