Abstract

ENGLISH: Return data for single-tagged fish and for double-tagged fish which had retained one or both tags were used to estimate the rates of shedding of dart tags from yellowfin tuna. The Type-1 shedding, which occurs immediately after release of the fish, is about 10 percent. The Type-2 shedding is assumed to be constant throughout the life of the fish after tagging; it occurs at an instantaneous rate of about 0.278 per year. SPANISH: Se emplearon los datos de retorno de peces marcados con una sola marca y de peces marcados con doble marca los cuales han retenido una o dos marcas para estimar las tasas de pérdida de las marcas de dardo de atunes aleta amarilla. El Tipo-l de pérdida, que ocurre inmediatamente después de haber liberado el pez, es aproximadamente del 10 por ciento. El Tipo-2 de pérdida se supone que sea constante durante la vida del pez después de marcado; ocurre en una tasa instantánea cerca de 0.278 por año. (PDF contains 24 pages.)
