Abstract

Small-scale capture fisheries condition is multi gear and multispecies has an impact on increasing the pressure of fish condition. The information related to fisheries resource status is very essential in order to build sustainable fisheries management planning. This study aims to analyze the level of fishing gear productivity, clustering of fishing gear based on the number of catch fish in Prigi, East Java. These study results are expected as sustainable small-scale fisheries management recommendations. This research methods were used the analyzed of diversity by Shannon-Wiener index, catch per unit effort (CPUE) and clustering of fishing gear based on a combination between principal component analysis (PCA) and hierarchical cluster. The results showed that the composition of the catch in each fishing gear was varied. The highest diversity of fish used gillnet as fishing gear. In general, the type of fishing gear with the most catches in AFP Prigi is handline, meanwhile scoop net became the highest CPUE of fishing. Clustering of fishing gear tends to be the same with varying proximity and gillnet fishing gear is a fishing gear that tends not to group with other tools. This study resulted that the clustering of fishing gear tends not to change in the last 10 years, however the correlation between groups are dynamic and this case has an impact on the variations of catch fish and fishing gear productivity.

Abstract

Pacitan Regency has quite prospective marine fishery potential. The fishing gears that are mostly used in Tawang Fish Auction Place (FAP) Ngadirojo, Pacitan Regency are hand line, krendet, parel and gillnet. Gillnets are fishing gear commonly used by fishermen to catch tuna (Euthynnus affinis) and layur (Trichiurus lepturus). The purpose of this research is to evaluate gillnet fishing techniques and assess the financial feasibility of gillnet fishing at Tawang Fish Auction Place (FAP) in Ngadirojo. This study was carried out in June 2022. A survey was used as the research approach. Technical analysis methods include examining the characteristics of the fishing fleet, fishing operations, and fishing regions. The business financial analysis method used is profit, R/C ratio, payback period, NPV, IRR, B/C ratio, and sensitivity analysis. According to the results of a study, gillnet boats are 1-3 GT in size and contain a 15 PK propulsion engine. Gillnet fishing gear is composed of polyamide monofilament with a length of 35-100 meters per piece and a width of 3-15 meters overall. The financial analysis of the gillnet fishing business at Tawang Fish Auction Place (FAP) Ngadirojo in Pacitan Regency shows that it is feasible to continue, with an average profit of IDR59.855.458,- per year, the R/C ratio is 2.06, and the net present value is IDR134.517.806,-. The IRR is 36.52%, the Payback Period is 1.27, and the analysis period is five years. According to sensitivity analysis, the limit for decreasing fish catch production was 73%. Based on the coefficient variation value, the level of production and price risk indicates that the gillnet fishing business has a low level of production and price risk and avoids losses.
