Biology and Distribution of the Yellowfin Tuna in the Tropical Part of Atlantic Ocean (Biologiya i Raspredelenie Zheltoperogo Tuntsa (Neothunnus albacora Lowe) v Tropicheskoi Chasti Atlanticheskogo Okeana),

Abstract

The paper discusses the Soviet observations of tuna fishes which were carried out in the coastal belt of S America, W Africa and the tropical zone of the Atlantic Ocean during 1959-1962. Since the species consists of two distinct groups, larger and smaller tunas, the distribution, migration and concentrations of these groups are charted separately, pointing out the hydrological conditions that favor the concentrations of these fishes, i.e., the upwelling, convergence and divergence belts, variations of water temperature, salinity and phosphorus content.
