Stomach content analysis of the Atlantic Sharpnose Shark from the Northeast Gulf of Mexico from 2000 to 2003 (NCEI Accession 0164788)

Description

Atlantic sharpnose shark Rhizoprionodon terraenovae diet is described from Crooked Island Sound, an embayment of the northeast Gulf of Mexico. Diet was assessed by life-stage and quantified using six indices: percent by number, percent by weight, frequency of occurrence, the index of relative importance (IRI), IRI expressed on a percent basis (IRI), and IRI based on prey category (IRIPC). Young-of-the-year sharks (n56) fed on a mix of teleosts (mostly clupeids, 44.6 IRIPC) and invertebrates (combined, 25.1 IRIPC), juveniles (n185) on sciaenids (40.7 IRIPC) and clupeids (37.8 IRIPC), and adults (n105) on sciaenids (71.4 IRIPC). Differences in diet by site and ontogeny were tested by comparing diet from Crooked Island Sound with published information from St. Vincent Island in Apalachicola Bay, an adjacent estuary. Stomach contents were also used to expand on published prey size-predator size information.
