Analysis of production factors that affect the productivity of tuna handliners based in Bitung Oceanic Fishing Port

Tuna hand lines have been used widely by fishermen in the waters of Sulawesi Sea and Moluccas Sea, to catch big pelagic species with small fishing boats (2-10 GT). Although the gear’s design has evolved over centuries, there is still potential for improving its catching efficiency and selectivity. However, the production factors that affect the productivity are still not known. The research aimed to study several production factors that affect the productivity of tuna hand liner based in Bitung Oceanic Fisheries Port; and to determine the most influential production factors on productivity of tuna hand liner. This research was conducted from June to November 2017 in Bitung Oceanic Fishing Port through applying a descriptive method based on case study; and the data were analyzed by using multiple linear regression production function. It was found that production factors that may affect the productivity of the tuna hand liner consist of boat size (GT), engine power (PK), amount of fuel (l), number of crew (person) and number of trips (days). The result of partial analysis shows that the most influential production factor to tuna hand liner productivity is the amount of fuel usage.
