Description
Summary:17 pgs. A fish trawl was pulled behind the R/V Western Gulf at one location in the Aransas Bay system during September 1976 - March 1977 to sample large (> 700 mm) red drum (Sciaenops ocellata) and other finfishes. The total number of fish and species caught generally declined from September through March as did water temperature and salinity. Catches of blue crab (Callinectes sapidus) were significantly (p < 0.05) higher at night than during the day. Trawling did not appear to be suitable for sampling large fish in deep portions of the Aransas Bay system perhaps because of the deep draft (3.3 m) of the Western Gulf. http://gbic.tamug.edu/request.htm
