Careful Release Protocols for Sea Turtle Release with Minimal Injury
"[S]ea turtle handling protocols, prepared by NOAA Fisheries Southeast Fisheries Science Center, describe the tools and techniques for removing fishing gear from incidentally captured sea turtles and other bycatch species. ... The required and recommended equipment and techniques described here are intended to reduce sea turtle injury and promote post-release survival. ... Although these guidelines were written for sea turtle release, this equipment should also be used for all bycatch species to reduce mortality"--Introd.
A Universal Method for Preparing, Sectioning, and Polishing Fish Otoliths for Daily Ageing
"The techniques for using otoliths for annual age determinations in fish are well established (Williams and Bedford 1974). The roughly seasonally alternating pattern of opaque material deposition during fast growth and hyaline material deposition during slow growth, allows researchers to assign an annual age to the fish. pannella (1971, 1974) discovered finer increments in the otoliths and suggested they represented the daily growth. Brothers et ale (1976) later confirmed the daily periodicity of the increments and using SEM showed that these increments were the smallest cyclical units found in the otolith of Engraulismordax. These increments are composed of incremental and discontinuous units. The discontinuous unit is relatively less calcified and is mostly composed of the protein otolin while the incremental unit is mostly composed of aragonite (Campana and Neilson 1985)"--Introduction, paragraph 1.
The Leatherback Turtle
The most comprehensive book ever written on leatherback sea turtles. Weighing as much as 2,000 pounds and reaching lengths of over seven feet, leatherback turtles are the world’s largest reptile. These unusual sea turtles have a thick, pliable shell that helps them to withstand great depths—they can swim more than one thousand meters below the surface in search of food. And what food source sustains these goliaths? Their diet consists almost exclusively of jellyfish, a meal they crisscross the oceans to find. Leatherbacks have been declining in recent decades, and some predict they will be gone by the end of this century. Why? Because of two primary factors: human redevelopment of nestin...
A Bibliography of NOAA Technical Memoranda Issued by the Southeast Fisheries Science Center of the National Marine Fisheries, 1972-1993
"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...
