  • Definition of Overfishing and Trend Analysis for Brown, White, and Pink Shrimp 

    Nance, James M. (U.S. Department of Commerce, National Oceanic and Atmospheric Administration, National Marine Fisheries Service, Southeast Fisheries Science Center, Galveston Laboratory, 1992)
    Nine shrimp species contribute to the Gulf of Mexico fishery. However, brown, white and pink shrimp of of the genus Penaeus comprise over 95% of the commercial harvest. These three shrimp species are found in all continental ...
  • Estimating Shrimp Fishing Effort 

    Nance, James M. (U.S. Department of Commerce, National Oceanic and Atmospheric Administration, National Marine Fisheries Service, Southeast Fisheries Science Center, Galveston Laboratory, 1992)
    To estimate shrimp fishing effort for each location cell (statistical subarea/depth zone) on a monthly basis, there must be two elements of data for each cell: 1)total pounds of shrimp caught by species and, 2)the average ...
  • Gulf of Mexico Pink Shrimp Assessment Modeling Update From a Static VPA to an Integrated Assessment Model Stock Synthesis 

    Hart, Rick A.; Nance, James M. (National Oceanic and Atmospheric Administration National Marine Fisheries Service, 2010-06)
    This report is intended as a template to document and outline the steps taken to update the SEFSC shrimp stock assessment models.
  • Incidental Capture of Sea Turtles in Shrimp Trawls With and Without TEDs in U.S. Atlantic and Gulf Waters 

    Renaud, Maurice L.; Nance, James M.; Scott-Denton, Elizabeth; Gitschlag, Gregg R. (Chelonian Conservation and Biology, International Journal of Turtle and Tortoise Research, 1997-04)
    The intent of this note is to estimate catch rates of turtles in shrimp trawls, excluding try nets, with and without TEDs in U.S. waters.
  • Offshore Oceanographic and Environmental Monitoring Services for the Strategic Petroleum Reserve - Response to Decision Maker's Questions: Benthos - FINAL 

    Nance, James M.; Harper, Donald E., Jr. (, 1985)
    The seemingly infinite capacity of the oceans to absorb and hide refuse has been used by man to dispose of all manner of material for thousands of years. Most of this material was relatively innocuous and there was not ...
  • Texas Closure/Tortugas Closure 

    Nance, James M. (U.S. Department of Commerce, National Oceanic and Atmospheric Administration, National Marine Fisheries Service, Southeast Fisheries Science Center, Galveston Laboratory, 1992)
    In 1976 the United States extended its jurisdiction over fisheries, exclusive of tuna, to 200 nautical miles and provided a program of management. Before that time fisheries in the territorial sea were managed by the ...
  • Virtual Population Analysis 

    Nance, James M. (U.S. Department of Commerce, National Oceanic and Atmospheric Administration, National Marine Fisheries Service, Southeast Fisheries Science Center, Galveston Laboratory, 1992)
    Virtual population analysis is used to make age specific estimates of the instantaneous rates of fishing mortality (f) and stock sizes for each shrimp species. The analysis: 1) a complete and accurate catch by age table, ...
