摘要

This paper provides a reference document for researchers interested in the typesof prey eaten by fishes and two common species of squids if continental shelf waters off the northeastern United States The stomach contents of 31,567 individuals representing 180 species were analyzed. Collection of specimens was primarily by bottom trawl or longline during 1963-84. Most of the smaller-sized fish species (i.e., < 100 cm long) and the two squid species were collected by bottom trawl during 1977-80. Most of the apex predators, including the large sharks and tunas, and other large-sized species were collected by longline. Dietary data are initially presented as a summary table which lists for each of 170 predators the relative contribution of six major functional prey groups (i.e., fish, squid, polychaete, decapod crustacean, other crustacean, and all other) to its diet. Such data are subsequently presented as summary tables which list for each of those six functional prey groups the predators involved and the relative contribution of seven geographic areas (i.e., Middle Atlantic, Southern New England, Georges Bank, Gulf of Maine, Scotian Shelf, inshore north of Cape Hatteras, and south of Cape Hatteras) to each predator's consumption of that functional prey group. Also, appendix tables provide a detailed listing of the overall stomach contents for each predator species and, for selected species, the stomach contents according to predator size, or to both predator size and geographic area of collection.
