Abstract

Kerinci Lake is a type of tectonic lake located in the Kerinci Regency, Jambi Province. The fishing gear such as tangkul/ pesap, nets (trawls), and traps (lukah) are commonly used in Telago Village. This research aims to investigate the effect of soaking duration of trap fishing gear on the catch of freshwater lobster. This research was conducted from February 27 to March 18, 2024. An experimental fishing method was employed, comparing soaking durations of 24 hours and 12 hours. Quantitative data were analyzed using frequency of occurrence, followed by T-test analysis. The results showed that a 24-hour soaking period yielded 237 lobsters with an average weight of 34.75 grams, with the highest frequency of occurrence at 44% and the lowest at 24%, averaging 33.20%. In contrast, a 12-hour soaking period resulted in 119 lobsters with an average weight of 33.88 grams, with the highest frequency of occurrence at 32% and the lowest at 8%, averaging 17.60%. T-test analysis indicated no significant effect of soaking duration on the number of lobsters caught, average weight, or depth-related environmental parameters. However, significant effects were observed for environmental parameters such as temperature and pH. In conclusion, while soaking duration does not significantly affect the catch of freshwater lobster (Cherax quadricarinatus), the 24-hour soaking period resulted in a higher yield.

Abstract

Pelabuhan Perikanan Nusantara (PPN) Sibolga, a key capture fisheries hub in North Sumatra, supports a range of services and activities for fishing stakeholders. Purse seine vessels, predominantly used by fishermen at PPN Sibolga, target pelagic species such as kawakawa (Euthynnus affinis), yellowfin tuna (Thunnus albacares), and skipjack tuna (Katsuwonus pelamis). This study analyzes income disparities among fishermen based on the profit-sharing system applied to purse seine vessels at PPN Sibolga. Conducted from March 4 to April 4, 2024, the study employed a survey method, collecting primary data on fish weight (kg), selling price (IDR), vessel size (GT), and operational costs, alongside secondary data on fishing gear statistics and regional information from PPN Sibolga. Data were analyzed descriptively to elucidate the income-sharing structure. Findings indicate that the average operational cost per trip for a purse seine vessel is IDR 199,458,550, with an average revenue of IDR 443,046,000 and a net profit of IDR 232,597,867. The profit-sharing system allocates 60% of the net profit (after fixed costs) to the vessel owner and 40% to the crew, with the skipper receiving 8.10%, senior crew (engineers, officers, cooks) 5.40%, supporting crew 4.05%, and regular crew 2.70%. The study reveals significant income disparities among crew members, driven by their roles and the established profit-sharing structure in purse seine operations at PPN Sibolga
