Abstract

Stomach analysis was done on 267 young-of-year longnose gar, Lepisosteus osseus, (17-276 mm, total-length) taken from Lake Texoma, May 8 to August 23, 1965. Feeding apparently occurred at the surface to a considerable degree, and occurred more actively at night than during the day. Gar in the initial feeding stages (17-21 mm, total-length) fed on a wide variety of items, including entomostracans, insects, and fish. Excepting the initial feeding stage, young-of-year fishes were the predominant food items in gar of all sizes. Menidia audens represented 84%, by number, of the fishes that had been eaten. Evidence indicates that there is some degree of competition for M. audens between young gar and the young of certain game fishes.
