Geographical distribution of yellowfin tuna and skipjack catches from the Eastern Tropical Pacific Ocean, by quarters of the year, 1952-1955
ENGLISH: In a previous Commission Bulletin, Shimada (1957) has described the geographical distribution of the yearly catches of yellowfin tuna (Neothunnus macropterus) and skipjack (Katsuwonus pelamis) from the EasternPacific Ocean for the period 1952 to 1955 inclusive, based on information obtained from logbook records of baitboats and purse-seiners. In view of the seasonal nature of the fishery in different areas, a summary of thecatches by smaller time units may be of additional value. Accordingly, statistical data employed earlier by Shimada have been retabulated by quarters of the year and form the basis of the present report. SPANISH: En un Boletín anterior de la Comisión, Shimada (1957) hizo un estudiosobre la distribución geográfica de las pescas anuales de atún aleta amarilla (Neothunnus macropterus) y barrilete (Katsuwonus pelamis) del Océano Pacifico Oriental, en el perlado comprendido por los años 1952 a 1955 inclusive. Dicho estudio fué hecho sobre la base de la información obtenida en los registros de las bitácoras de los barcos carnaderos y rederos. Pero en vista de la naturaleza que imprimen las estaciones a la pesquería en lasdiferentes áreas se ha considerado que podría tener valor complementario un resumen de las pescas en unidades de tiempo menores. De acuerdo con este criterio, los datos estadísticos empleados antes por Shimada, se hantabulado de nuevo ahora, por trimestres, y constituyen siempre la base del presente informe.(PDF contains 49 pages.)
