  • Description:
    The National Marine Fisheries Service (NMFS) proposes to issue a modification to a research permit to Dewayne Fox, PhD., for takes of Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) in the wild, pursuant to the Endangered Species Act of 1973, as amended (ESA; 16 U.S.C. 1531 et seq.). The modification would be valid through April 5, 2017. The objectives of the research for Atlantic sturgeon would remain unchanged: to collect data on the biology, distribution and abundance of endangered Atlantic sturgeon to facilitate recovery of the species. Three projects fall under the permitted research. The first project authorizes directed mortality of Atlantic sturgeon eggs. As part of the second project, a hydroacoustic assessment survey, 100 Atlantic sturgeon are authorized for capture by gill net, and for measuring, weighing, tissue sampling, and PIT tagging. The third involves the capture of 300 Atlantic sturgeon annually by gill net throughout Delaware's coastal waters, and in the Delaware Bay and River. All captured Atlantic sturgeon are measured, passive integrated transponder tagged, tissue sampled, and released. Subsets of captured Atlantic sturgeon are fitted with internal satellite tags or external pop-off satellite tags; sampling also includes gonad tissue biopsy. The applicant now requests authorization for 100 annual shortnose sturgeon (Acipenser brevirostrum) takes for the remainder of the permit; all capture methods, action areas and activities would remain the same as for the currently authorized Atlantic sturgeon takes. The authorization to sample an additional sturgeon species would allow the permit holder to test use of a hydroacoustic assessment method for shortnose sturgeon which is currently authorized for Atlantic sturgeon.
