Item Biological Survey of the Commercial Shrimp and Associated Organisms in the Inshore Gulf of Mexico - Study of the Texas Shrimp Populations(Texas Parks and Wildlife Department, 1964) Compton, Henry, Jr.; Texas Parks & Wildlife Coastal Fisheries Project Report 1964Regular stations were set up for weekly samples in the inshore Gulf off Port Aransas, Texas, in depths of 2 to 15 fathoms, in the inshore Gulf off of Port Mansfield, and Port Isabel, Texas for monthly samples in 2 to 20 fathoms, and in the inshore Gulf off Galveston samples under 10 fathoms annually. Brown shrimp, Penaeus aztecus, were very abundant in the southern Gulf off Port Isabel in May and were predominantly undersize; this same situation existed in June in the Gulf off Port Aransas. Significant numbers of white shrimp, P. setiferus, were found off Port Aransas in January when most were undersize. Pink shrimp, P. duorarum, were most abundant in May off Port Isabel. Seabobs, Xiphopeneus kroyeri, were abundant in January off Port Aransas and were not taken in the southern zone. Abundance of the various species was not noticeably different from that of 1963. Salinity and temperature were similar to those of 1963. Undersized brown shrimp could profitably be protected in the southern waters beginning in May and beginning in June off Port Aransas. Protection of small white shrimp in the southern waters at any time is probably unnecessary, although protection is indicated for the inshore gulf off Port Aransas in January.Item Survey of Fish Populations in the Inshore Gulf of Mexico off Texas(Texas Parks and Wildlife Department, 1966) Compton, Henry, Jr.; Texas Parks & Wildlife Coastal Fisheries Project Reports 1965Fish populations in the inshore Gulf of Mexico off Port Aransas, Texas, Port Mansfield and Port Isabel, Texas and briefly off Galveston, Texas, were surveyed for type, abundance and size with a flat otter trawl. In regular weekly samples, 25,044 fish of 89 species were caught in 100 otter trawl samples. Atlantic croaker, Micropogon undulatus; sand trout, Cynoscion nothus; moonfish, Vomer setapinnis; bumper, Chloroscombrus chrysurus; and shoal flounder Syacium gunteri, were the five most abundant species taken in depths ranging from 3 to 16 fathoms. These results indicate that enough trash fish may be caught during routine shrimp trawling to sustain a profitable fishery if a market develops. No attempt was made to evaluate the abundance of larger food or game fishes.Item Survey of Shrimp Populations in the Inshore Gulf of Mexico off Texas(Texas Parks and Wildlife Department, 1966) Compton, Henry, Jr.; Texas Parks & Wildlife Coastal Fisheries Project Reports 1965In 1965 shrimp and associated bottom organisms were sampled for type, abundance, size groups, and seasonal availability with a 23-25 foot flat otter trawl in the Gulf of Mexico off Port Aransas, Port Mansfield, Port Isabel, and briefly off Galveston, Texas. In regular weekly samples, commercial shrimp of four species, non-commercial shrimp of 7 species, two species of squid, and various associated animals were caught in 100 trawl samples. Brown shrimp, Penaeus aztecus, were the most abundant of the commercial species, followed by white shrimp, Penaeus setiferus, and pink shrimp, Penaeus duorarum. Trachypeneus similis and Squilla empusa were the most abundant non-commercial species. This survey indicates the seasonality of Gulf shrimp populations and the cyclic growth and migration patterns in inshore waters. Periods of abundance are noted for all shrimp. Growth cycle information is given for brown, white, and pink shrimp. Any variation of catch between areas sampled is noted, and data on non-commercial species area included for more comprehensive understanding of the ecology of the inshore Gulf of Mexico.
