Productivity of Yellowfin Tuna (Thunnus Albacares) by Using Hand Line in Majene Regency, Indonesia

Abstract

Productivity and production factors need to be studied in order to determine the steps that fisherm en could take to increase tuna production volume without causing significant losses. Therefore, this study examines the fishing productivity of tuna handliners and determine the factors with the most influence on their productivity. This research was conducted from August to November 2022 in Rangas Village, Banggae District, Majene Regency, Indonesia using a survey method and a purposive sampling technique. Data were analysed using multiple linear regression of the Cobb-Douglas production function. Fishing productivity was obtained from the ratio of the amount of catchesand duration of fishing time. The results showed that the relationship between fishing productivity with the time fishing is declining withincreasing duration of time fishing. Fishing productivity shows the downward trend. The factors affecting the productivity of the handline tuna fishery comprised vessel capacity (GT), engine power (HP), fuel volume (L), number of crew members (fishermen), and duration of fishing times (minute). The production factors with the greatest influence on the productivity of the handline tuna fishery was duration of fishing times (minute).
