Abstract

The two-boat bagan is one of the most common fishing gear used by fishers in Kao Bay. Its main fishing target is squid with various other types of fish as by-products. Two-boat bagan operations are carried out every night so it is necessary to ensure the best moon phase for more efficient and effective catch. The purpose of the study was to analyze the composition of catch and to analyze the productivity of fish species and the moon phase. The data collection method was conducted by interview and observation of fishing operations for one month. Data analysis was carried out descriptively, using the composition formula and productivity analysis. The results showed that there were 7 types of fish caught by two-boat bagan. Three most dominant species were fish with high economic value, each with their respective compositions were squid (41%), selar (30%), and mackerel (17%). The types of catch with the highest productivity were squid (111 kg/trip), followed by selar (86 kg/trip), and mackerel (64 kg/trip). Based on moon phase, the highest fishing productivity took place in moon-phase 3 (931 kg/trip), followed by phase 2 (718 kg/trip), phase 4 (685 kg/trip), and phase 1 (534 kg/trip).

Abstract

This study aims to: (1) describe the characteristics of the fish caught in each type of hand line that consisting: type, number, weight, hook depth, and size category of fish caught, (2) analyze the productivity of hand line fishing gears. The research method used was a survey method by following fishing operations on the two hand-lines around FADs. The research was conducted from July to August 2019 in the West Halmahera sea, North Maluku. This research used descriptive analysis and productivity analysis. The results of the study showed that the artificial bait bait type hand line caught 4 species of fish with a total of 135 individuals, while the hand line with natural bait caught as many as 30 individuals. The weight of the catch on the artificial bait type hand line was 258 kg while the natural bait type hand line catch was 757 kg. The artificial bait hand line had better catches at a depth of 40 m, while the natural bait type catches more at a 50 m depth. The artificial bait type hand line had a productivity value ranging from 3.7-6.6 kg/trip with an average productivity of 5.15 kg/trip. The natural bait type hand line had a higher value, which ranged from 8.43-21.71 kg/trip with an average productivity of 16.00 kg/trip.
