Examination of local movement and migratory behavior of sea turtles during spring and summer along the Atlantic Coast off the Southeastern United States : final project report
Loggerhead sea turtles inhabiting coastal waters along the southeastern United States represent the progeny of multiple rookeries. Tagging studies of nesting female loggerheads suggest that most return to the same beaches in successive breeding seasons and it is widely accepted that most females return to their natal regions to nest. The focus of the in-water survey was modified to intensively target one small trawling area to: (1) examine the effect of intensive trawling on recapture rates and (2) quickly obtain an adequate sample size of turtles to outfit with satellite transmitters. This annual report highlights the major findings for research activities primarily carried out during 2009
Biology and Management of Mid-Atlantic Anadromous Fishes Under Extended Jurisdiction- Completion Report Anadromous Fish Project 1977-1979
This is a joint presentation by the North Carolina Department of Natural Resources and Community Development, Division of Marine Fisheries (DMF) (Part I) and the Virginia Institute of Marine Science (VIMS), Department of Ichthyology (Part II).
It is for the period October 1, 1976 to September 30, 1979, and is the completion report for t:he P. L. 89-304 project Biology and Management of Mid-Atlantic Anadromous Fishes Under Extended Jurisdiction.
Species of concern are: alewife (Alosa pseudoharengus), blueback herring (Alosa aestivalis), hickory shad (Alosa mediocris), American shad (Alosa sapidissima), striped bass (Morone saxatilis), Atlantic sturgeon (Acipenser oxyrhynchus) and the shortnose sturgeon (Acipenser brevirostrum)
Partial poisoning to restore fish population balance in farm ponds
Balanced fish populations are those that provide quality fishing year after year. They
produce the food and prey necessary for young fish to survive and grow to a harvestable size. Balance is best achieved by properly stocking the pond with the correct number of largemouth bass and bream . Balance is maintained by managing water quality and by annually harvesting adequate numbers of bass and bream
Farm pond fertilization and liming
The fish productivity of any farm pond begins with the base of the food chain, the
phytoplankton population. Fertilization of a pond stimulates and expands the plankton population. Liming of soft, acid waters in South Carolina ponds can correct water quality deficiencies and improve the pond’s bass-bream production
Excavated pond construction and management
The following is a discussion of methods used to maximize quality fishing in excavated ponds located in the Coastal Plain. The discussion is divided into three parts: construction of the pond, manipulation of water quality, and fish population management
Managing ponds for recreational fishing
This publication provides South Carolina pond owners with guidance to increase their
pond’s potential to produce quality fishing year after year
Development of an index of sea turtle abundance based upon in-water sampling with trawl gear
This study was designed to provide fundamental data for the in-water population
of turtles along the southeast coast of the United States, with particular emphasis on
measuring abundance. Much of our knowledge of sea turtles has come from data
collected on nesting beaches or opportunistically during regulation of fisheries. Through
an in-water survey we hoped to provide a better understanding of turtle abundance,
spatial variability and population characteristics
