Penaeid Shrimp Tagging Experiments in Louisiana, 1979


Book Description

"Penaeid shrimp mark and recapture studies in Louisiana, initiated in 1977, were continued through 1979 in cooperation with the Louisiana Department of Wildlife and Fisheries (LDWF) and Louisiana State University. Shrimp were tagged and released in Caillou Lake, Barataria Bay and offshore between Calcasieu Pass and Grand Isle. The major program objectives were designed to meet data needs identified as management priorities in the regional shrimp fishery management plan for the Gulf of Mexico (Christmas and Etzold, 1977). They included investigation of growth, mortality and movement patterns of offshore overwintering populations of white shrimp (Penaeus setiferus) and to expand inshore studies of brown shrimp (P. aztecus) in Louisiana's extensive and productive estuarine systems to include white shrimp. This report summarizes recovery data from shrimp marked and released in Louisiana waters during 1979. Individual recapture data, including distance travelled, days at large and change in length, are presented in Appendix I. Growth rate and mortality rate estimates are beyond the scope of this paper and will be reported elsewhere"--Introduction
















A Bibliography of NOAA Technical Memoranda Issued by the Southeast Fisheries Science Center of the National Marine Fisheries, 1972-1993


Book Description

"The Southeast Fisheries Science Center (SEFSC) is one of five regional fishery research centers of the National Marine Fisheries Service (NMFS). In 1970, the NMFS was organized as a component of the National Oceanic and Atmospheric Administration (NOAA) in the U.S. Department of Commerce. The Fisheries Science Centers provide scientific information required for decisions relating to the conservation and management of fishery resources, and the protection of fishery habitats, endangered and threatened species. In 1972, the NOAA Technical Memorandum series was established and the Southeast Fisheries Science Center began the publication of research reports. The purpose of this series is timely dissemination of the results of scientific research. The series also affords the SEFSC a means of publishing research results in greater depth and detail than is normally allowed by scientific journals, which usually have stringent length restrictions. To address the difficulties of identification and location of these publications, we present the following listing of SEFSC Technical Memoranda from number 1 (1972) to number 340 (1993). They are available from their originating laboratories or from the National Technical Information Service. A directory of these sources is provided on page 2"--Introduction













A Summary of Results of Louisiana White Shrimp Tagging Experiments, 1977


Book Description

"The shrimp fishery in the Gulf and Atlantic coastal states is considered to be the most valuable fishery in the United States. The Gulf of Mexico has been the major production area for shrimp in the United States, accounting for approximately 80% of the total value of shrimp landed in this country. The directed shrimp fishery in the Gulf of Mexico harvests brown shrimp (Penaeus aztecus.), white shrimp (P. setiferus), and pink shrimp (P. duorarum). Of these species, brown shrimp account for approximately 53% of total production, while white and pink shrimp account for 26% and 15%, respectively. The state of Louisiana is the center of white shrimp production. In 1977, there were over 14 million kilograms (31.3 million pounds) of white shrimp (heads-off weight) landed at commercial businesses in Louisiana (USDOC, 1979). In 1977, NMFS contracted with the Louisiana Department of Wildlife and Fisheries to tag and release white shrimp in the Caillou Lake estuary system, in response to management priorities identified in the regional shrimp fishery management plan for the Gulf of Mexico (Christmas and Etzold, 1977). These priorities included the determination of estimates regarding growth rates, mortality rates, and migration patterns characterizing major penaeid stocks in the Gulf of Mexico. This report presents a summary of these mark-recapture experiments"--Introduction.
