Biological Survey of the Commercial Shrimp and Associated Organisms in the Inshore Gulf of Mexico - Study of the Texas Shrimp Populations

Regular 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

Survey of Fish Populations in the Inshore Gulf of Mexico off Texas

Fish 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

Survey of Shrimp populations in the Inshore Gulf of Mexico off Texas

In 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

Ecological Benefits of Creating Stormwater Wetlands and Woodlands in Philadelphia, PA

Urban development and wetland loss have negatively impacted water quality. Natural areas and systems can help mitigate those impacts. With over two centuries of utilizing the Schuylkill River as a source of drinking water, Philadelphia has adapted from land preservation to wetland creation to achieve sediment Total Maximum Daily Load (TMDL) standards. This case study highlights how the innovation of constructed stormwater wetlands coupled with the restoration of forested natural areas provides water quality and ecological benefits

TAILORED ADAPTIVE PERSONALITY ASSESSMENT SYSTEM (TAPAS) EXAM ABILITY TO PREDICT PROFICIENCY AND PERFORMANCE AMONG NAVAL ACADEMY PRODUCED MARINE CORPS OFFICERS

Approximately 25% of the midshipmen who graduate from the United States Naval Academy (USNA) receive a commission in the United States Marine Corps. The selection process examines a midshipman’s academic, leadership, and physical performance during their time at USNA, along with a Marine-led summer training called Leatherneck. We examine Tailored Adaptive Personality Assessment System (TAPAS) scores obtained during Leatherneck to determine if facets can improve the Marine Corps service assignment selection process. In addition, we examine individual facets to determine if they predict The Basic School (TBS) performance for USNA-produced Marine Officers. We found that adding TAPAS to data that the Marine Detachment (MarDet) considers for the selection process is likely to provide only a meager improvement. However, there are several TAPAS facets, such as optimism and academic achievement, that are positively correlated to performance at TBS, as well as sociability, which is negatively correlated to performance at TBS. Furthermore, combining the TAPAS data with existing selection metrics for the MarDet, we see an impact in the ranking positions for USNA-produced officers at TBS. While the data is significant, we recommend further studies to determine the full extent that TAPAS supports predicting performance for officers at TBS and potentially the success of Fleet Marine Force.Captain, United States Marine CorpsCaptain, United States Marine CorpsApproved for public release.

Effect of Fish Size on Prey Size Selection in Gambusia Affinis

Food size selection of the mosquitofish , Gambusia affinis affinis. was measured in aquaria using juvenile stages of the mosquito, Clllex tarsalb;, as prey. Fish size varied from recently born fry to large adult females. Food size selection was positively correlated with fish size. Mosquitofish fry (6-8 111m standard length) attacked and ate primarily first and second instar larvae. Fry attacked larger instars, but attack success on these was low (0 - 50%). Fish larger than 20 mm attached primarily pupae and third and fourth instar larva. No first instar mosquitoes were eaten. Attack success for these fish was above 65\u27Yr) for all instars
