"The National Marine Fisheries Service (NMFS) Southeast Fisheries Center I s Mi ami Laboratory has theresponsibil ity of collecting and analyz- ing data on certain pelagic marine fishes. This is part of a canmitment by the United States to develop national programs for conserving and manag- ing these species and to participate in cooperative international investi- gations through the International Commission for the Conservation of Atlan- tic Tunas (ICCAT). Information collected on these species is also used by regional Fishery Management Councils to formulate fishery management plans. The ICCAT is responsible for coordinating and guiding scientific investiga- tions on stocks of tunas and tuna-like fishes, including billfishes, in the Atlantic Ocean and adjacent seas. Data collected through NMFS programs are used in population modeling and in annual assessments of the status of stocks of Atlantic billfishes and tunas, and these results are presented to the international scientific community at ICCAT each year"--Preface, paragraph 1
This book focuses on latest information on the biology and ecology of the three bluefin tuna species: the Pacific (Thunnus orientalis), Atlantic (T. thynnus), and southern bluefin tuna (T. maccoyii). In the book, the phylogeny and basic ecological information such as early life history, age and growth, and food habits are covered. Information relat
Biology of Antarctic Fish presents the most recent findings on the biology of fish in the unique environment of the Antarctic ocean. At present the year-round temperature of the coastal waters is very near -1,87 ° C, the equilibrium temperature of the ice-seawater mixture. This extremely low temperature affects different levels of organization of fish life: individuals, organ systems, cells, organelles, membranes, and molecules. Exploring ecology, evolution, and life history as well as physiology, biochemistry, and molecular biology of Antarctic fish the book describes the mechanisms of cold adaptation at all these levels. It provides material for discussion also for fundamental questions in the field of adaptation to an extreme environment and therefore is of particular interest not only to specialized scientists, but also to those involved in basic and evolutionary biology.
