In the guts

Justin Matocha, above, cleans a red snapper on Thursday, July 2, as part of a study by Texas A&M University-Corpus Christi. The entrails of the fish, shown at left by associate research scientist at the Center for Coastal Studies at A&M-Corpus Christi, Dr. James Simons, were collected from about 10 red snappers and one king mackerel that were caught on a fishing tour. ‘What we are looking for is nitrogen and carbon isotope levels,’ Simons said. ‘The nitrogen isotope indicates the fish’s position in the food web, and the carbon isotope acts as an indicator of food source.’ Simons’ study will extend 100 miles offshore from Port O’Connor to Port Mansfield. Among the fish his study is collecting include snapper, grouper and large pelagics. The data collected will be used to advise fisheries managers about the effects of overfishing, oil spills and algal blooms.
