Book excerpt: "From 1971 to 1995, the U.S. National Marine Fisheries Service's (NMFS) Tuna- Porpoise Observer Program collected data on the mortality, life history, distribution and abundance of dolphins (colloquially referred to as 'porpoise') associated with yellowfin tuna (Thunnus albacares) in the eastern tropical Pacific Ocean (ETP) and their involvement in fishery operations. This program, which became mandatory for the U.S. fleet in 1976 under the Marine Mammal Protection Act, placed biological technicians ('observers') aboard commercial U.S. purse seiners holding certificates of inclusion under a general permit to take (chase and/or set nets on) certain species of dolphins within the 'permit area' (that area of the Pacific Ocean bounded by 40°N latitude, 40°S latitude, 160°W longitude and the coastlines of the Americas). The ETP yellowfin tuna purse seine fishery exploits the tuna-dolphin association by netting the highly visible, surface-swimming dolphins in an attempt to catch the tuna schooling below them. Dolphins may be killed in the purse seines before they can be separated from the tuna and returned to the open ocean. Most frequently killed in this fishery are dolphins of the genus Stenella and, to a lesser extent, the genus Delphinus. The purpose of this paper is to describe the data collected under Tuna-Porpoise Observer Program from 1971-1990 and archived by the Southwest Fisheries Science Center's (SWFSC) Protected Resources Division (PRD)"--Introduction.

Beerkircher and published by . This book was released on 2009 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Atlantic Bluefin tuna, Thunnus thynnus, is a large apex teleost that inhabits the pelagic environment in temperate and subtropical waters of the North Atlantic. While the species engages in long seasonal migrations throughout its range, it is believed that two major stocks exist, one in the eastern Atlantic and Mediterranean and one in the western Atlantic and Gulf of Mexico (Block et al., 2005). In the west, spawning activity is concentrated in the Gulf of Mexico during April, May, and June (Mather et al., 1995). The decline of both Eastern and Western stocks of Atlantic bluefin tuna has been well documented and the species is subject to major rebuilding efforts (ICCAT, 2007). Part of the rebuilding effort has been to increase the amount of information known about the basic biology of bluefin tuna, as well as collecting robust information regarding fisheries catch and bycatch. In the spring of 2007, and again in the spring of 2008, the National Marine Fisheries Service (NMFS) conducted enhanced observer coverage of the U.S. pelagic longline fleet operating in the Gulf of Mexico (GOMEX) in order to accurately quantify and characterize bluefin tuna bycatch in this fishery during spawning season, as well as collect biological samples to support various research into bluefin tuna age and growth, maturity, and reproduction. Here we provide background information on the GOMEX longline fishery and the summary statistics of the observer data collected during bluefin tuna spawning season coverage in 2007-2008; as well as analyses of levels of observer coverage needed to provide bycatch estimates of various precisions"--Introduction.
