Description
Summary:Harvesting characteristics (size composition and catch rates) of the U. S. and Spanish fleets are examined in light of gear and operating (time-area) practices latitude and between in the north Atlantic between 40° and 50° north 20° and 50° west longitude, The two fleets have approached and overlapped operations in this area between 1983 and 1985. During 1986 the degree of overlap continued to increase. Se examinan las características (composición por tallas y tasas de capturas) de la captura de las flotas española y estadounidense, a la luz de los artes empleados y del tipo de operación llevada a cabo (tiempo-zona) en el Atlántico Norte, entre 40 - 50º de latitud Norte y 20- 50º grados de longitud Oeste. Las operaciones de ambas flotas han estado bastante cerca nas y se han solapado en esta zona durante el periodo 1983-85. En 1986 cont1nuó en aumento el grado de solapamiento. Les caractéristiques d'exploitation (composition de taille et taux de capture) des flottilles américaine et espagnole sont examinées à la lumière des engins et méthodes normalement employés dans l'Atlantique nord entre 40º et 50°N de latitude, et 20º et 50ºW de longitude. La pêche de ces deux flottille s'est rapprochée, et même recoupée, dans ce secteur entre 1983 et 1985. En 1986, le degré de chevauchement a continué de s'accroitre.
