During the FRS OREGON II Texas Closure operations between 4 June and 4 July 1981, samples of trawl-caught finfish were obtained. The objectives of the study were to record the number of Penaeus spp. found in trawl-caught fishes and to document shrimp predator species. The stomachs from the trawl-caught fishes were examined for the presence of brown (Penaeus aztecus), white (P. setiferus), and pink (P. duorarum) shrimp. Thirteen brown shrimp were identified from the stomachs of 7598 fish. The collected data were compiled for further examination to determine the impact of fish predation on shrimp stocks and to estimate natural mortality due to predation.
