Abstract

ENGLISH: Most of the catches of yellowfin and skipjack tuna from the Eastern Pacific Ocean are made by vessels fishing with poles and lines and live bait. From 1931 to 1954, these baitboats, on the average, accounted for over three-fourths of the total annual California landings of yellowfin and skipjack (Shimada and Schaefer, 1956). With the substantial increase in recent years in the production of the tropical tunas, there have been greater demands for live bait. This increased need for larger amounts of baitfishes has given rise to important questions relating to the manner in which these populations may be most wisely used. The Inter-American Tropical Tuna Commission has been concerned with various aspects of this problem since its establishment in 1950. This report presents some of the results obtained from the Commission's studies of the baitfishes important to the fishery for yellowfin and skipjack tuna. It traces briefly the origin and development of the bait fishery, describes its operations, extent, and yield, and discusses some aspects of the effects of exploitation upon the Eastern Pacific baitfish populations, particularly of the anchoveta (Cetengaulis mysticetus). SPANISH: Los barcos que emplean cañas y cuerdas y carnada viva, son los que realizan la mayor parte de la pesca de atún aleta amarilla y barrilete en el Océano Pacifíco Oriental. De 1931 a 1954 estos barcos han desembarcado, en promedio, más de las tres cuartas partes de las pescas anuales de ambas especies (Shimada y Schaefer, 1956). Con el aumento sustancial en dicha producción en los últimos años, ha habido una mayor demanda por carnada viva. Esta creciente necesidad de obtener cantidades mayores de pecescebo, ha originado importantes cuestiones relativas a la mejor forma en que estas poblaciones pueden ser utilizadas. A la Comisión Interamericana del Atún Tropical le ha tocado ocuparse de varios aspectos de este problema, desde que fué establecida en el año 1950. Este informe ofrece algunos de los resultados obtenidos a través de los estudios de la Comisión sobre los peces-cebo importantes para la pesquería de atún aleta amarilla y barrilete; señala brevemente el origen y desarrollo de la pesquería de carnada; describe sus operaciones, extensión y rendimiento, y trata algunos aspectos de los efectos de la explotación sobre las poblaciones de dichos peces en el Pacifíco Oriental, particularmente de la anchoveta (Cetengraulis mysticetus).
