Field Guide to Freshwater Invertebrates of North America
James Thorp, and D. Christopher Rogers, (eds.)
- The Field Guide to Freshwater Invertebrates of North America focuses on freshwater invertebrates that can be identified using at most an inexpensive magnifying glass. This Guide will be useful not only to researchers and students in aquatic biology, but also to anglers who use identification of invertebrates to identify fertile fishing areas. Color photographs and art, as well as the broad geographic coverage, set this guide apart.
Asessment of the white shrimp fishery (Litopenaeus setiferus) in the Campeche Bank, southern Gulf of Mexico
J. Ramos-Miranda, D. Flores-Hernández, and T. Do Chi
- The purpose of this study was to analyze the current state of the fishery of white shrimp (Litopenaeus setiferus) in the Bank of Campeche, through analytic models. The used source of data corresponded to the structure in size of the captures carried out by 133 boats of the artisanal fleet and 203 ships of the industrial fleet among March from 1998 to April of 1999. Landing information month data was taken from the Environment Secretary, Natural Resources and Fisheries in Campeche. The evaluation of the stock was carried out through a diagram of exploitation obtained by pseudo-cohorts analysis.
Frontiers of Shrimp Research
P.F. DeLoach M.A. Davidson, and W.J. Dougherty (eds.)
- Shrimps are subject to great consumer demand in the United States. However, more than #1 billion worth of shrimp is now imported; more than twice the amount produced domestically. Domestic shrimp production, mostly from the trawler fleet in the Gulf of Mexico, is thought to be at its maximum sustainable yield of 91 000 MT (heads-off). Increased production of shrimp in the U.S. through mariculture has been motivated by the increasing demand for this product. The biology of penaeid shrimp and lack of technology for their culture present special problems in fisheries science, reproductive biology, endocrinology, nutrition, pathology, culture science and future research. The purpose of the Frontiers of Shrimp Research symposium was to assess the status of shrimp research in these areas and to further foster the scientific collaboration vital for significant research advances. The participants included representatives of the science funding agencies, the mariculture industry and representatives of both the scientific research and science policy communities. The subject matter should be of interest to a variety of readers. Advanced undergraduate/graduate students, mariculturists and research workers will find this volume both interesting and informative.
Shrimp Fishery and Sea Turtle Concerns
Eugene H. Buck
- Sea turtles, almost all species of which have been declared threatened or endangered, can be inadvertently caught and drowned in trawl nets pulled by fishing vessels harvesting shrimp. The United States has reduced sea turtle mortality by requiring U.S. shrimp trawlers to use turtle excluder devices (TEDs) to reduce turtle drownings; however, turtle mortalities from some foreign shrimp vessels might still be substantial. The use of TEDs reduces the efficiency of shrimp trawling; some domestic shrimpers contend the economic impacts are severe. Efforts to reduce finfish bycatch during shrimp trawling could result in additional restrictions or regulations on shrimp harvesters.
