| Resumo: | [EN] This document presents a detailed study of the skipjack (Katsuwonus pelamis) fishery in the Canary Islands during the period from 1926 to 2020. There is clear evidence of the existence of this fishery since the beginning of the 19th century on the island of La Gomera. The fishing effort for the different fleet segments and all period is analyzed. Total catches of skipjack have oscillated in saw tooth pattern, with good years and bad years. The skipjack catches is directly related to bigeye catches, representing in many years more than 40% of the total catches in the islands. The seasonality of catches of the species has not changed in the last 25 years, with the second and third quarters being the most important in terms of catch volume. Catch sizes are smaller in the second and third quarters. And the largest sizes are captured in the free school mode and mainly in the winter months such as December, January and February. Skipjack catches are made mainly in coastal areas and inter-island channels by vessels of less than 50 GRT. |
