【 摘 要 】

The study aims to analyse the value of CPUE and the factors which influenced the Skipjack Tuna fishing production at the Sibolga Nusantara Fisheries Port (PPN). This research was conducted at PPN Sibolga, Central Tapanuli Regency. The research was conducted using a descriptive method with sample of 40 fishermen of purse seine vessels (ship captains) determined through purposive sampling technique. Data analysis techniques were carried out by using CPUE value analysis and multiple linear regression analysis. The results showed that: (1) CPUE value of Skipjack Tuna landed at PPN Sibolga for a period of 6 years (2011-2016) experienced fluctuating decline and increase. The average CPUE value was 199.70 kg/trip. The highest CPUE value occurred in 2016 was 412.24 kg/trip and the lowest CPUE value occurred in 2015 was 32.70 kg/trip; (2) partially, the factors of the fisherman experience, the size of the ship, the power of the engine and the length of the trip had a significant effect on the skipjack tuna fishing production. Meanwhile, the amount of fuel did not have a significant effect. Trip duration was the dominant factor or had a strong influence in the fishing production of skipjack tuna.
