Fisheries -- United States; Fish-culture -- United States. 106 BULLETIN OF THE BUREAU OF FISHERIES is pale gray instead of black, and there is also a slight difference in outline, the hickory shad being the deeper of the two, with a more tapering head, its lower jaw projecting relatively farther. The hickory shad is distinguishable from the common alewife (in which the lining of the belly is likewise gray) by tapering forward from its greatest depth, whereas the latter is heavy bodied forward of the dorsal and ventral fins, as well as by its sharp head, longer jaw, smaller dorsal fin, only about one-half as many gill rakers (about 30 on the first gill arch), and, under favorable circumstances, by its color, being faintly marked on the sides with longitudinal stripes. The projecting lower jaw of the hickory shad marks it off from the shad. Size.—This, next to the shad, is the largest of our anadromous herrings, growing to a length of 2 feet and a weight of 2% pounds. General range.—Atlantic coast of North America from the Bay of Fundy to Florida, running up into fresh water to spawn. Occurrence in the Gulf of Maine.—The hickory shad is a more southern fish than either of the alewives, the Gulf of Maine marking the extreme northern limit to its range. So far as known, it does not breed in any of the rivers north of Cape. Fig. 43.—Hickory shad (Pomolobus mediocris) Cod and is so rare a fish within its limits that although recorded from the mouth of the Bay of Fundy (Huntsman doubts this record), from Casco Bay, off Portland, at the mouths of various rivers in Maine where odd fish are taken from time to time by gill-netters, in Boston Harbor, at Provincetown, and at North Truro in Massa- chusetts, we have not seen a single specimen among the thousands of herring and alewives that have passed through our hands. West of Cape Cod, however, it is much more plentiful, being common from spring throughout summer and earl
