Abstract

Capture fisheries are one of the most contributing sectors in producing fishery products.The fourfinger threadfin (Eleutheronema tetradactylum) is one of the key commodities in the capture fisheries sector of Pasuruan City. The catch yield of this species is influenced by the mesh size of the gillnet used. This study aimed to determine the effect of different mesh sizes on the catch yield of fourfinger threadfin and to identify the most effective mesh size. The research was conducted using an experimental fishing method with a Randomized Block Design (RBD) comprising three gillnet mesh size treatments: 1.75 inches, 2.5 inches, and 4 inches, with nine fishing trips. Data on catch weight and number were analyzed using a One-Way ANOVA followed by the Least Significant Difference (LSD) test. The ANOVA results showed an F-value of 10.083 with a significance level of 0.001 (p-value < 0.05), indicating a significant difference in the catch weight of fourfinger threadfin (Eleutheronema tetradactylum) among the mesh size treatments. This finding suggests that mesh size has a significant effect on catch weight, with the 2.5-inch mesh size being the most effective for catching fourfinger threadfin in the Madura Strait, as it produced the optimal catch weight compared to 1.75-inch and 4-inch mesh sizes.

Abstract

Bluru Kidul Village is an area located near the northeastern coast of Sidoarjo, where its geographical position provides significant benefits for the community. Consequently, the majority of residents work as fishermen and live side by side with the marine ecosystem. Due to the existence of Bluru Kidul Village, Sidoarjo City is often referred to as a fisheries or coastal city. The fish resources in these waters are dominated by small pelagic fish, large pelagic fish, and demersal fish. One of the most widely used fishing gears is the gill net. This study applied treatments with soaking durations of 2 hours, 3 hours, and 4 hours. The objectives of this research were to identify the composition of gill net catches, analyze the effect of different soaking times on gill net catches, and determine the optimal soaking duration for catching Indian mackerel (Rastrelliger) using gill nets. Data analysis was conducted using statistical methods, including analysis of variance (ANOVA) and normality tests to ensure data suitability. To determine whether soaking duration had a significant effect, a further statistical test, namely the Least Significant Difference (LSD) test, was applied to identify which soaking time produced the best catch of Indian mackerel. The results indicated that there were significant differences in catch variables between the 4-hour treatment and the 3-hour and 2-hour treatments, whereas the difference between the 3-hour and 2-hour treatments was not significant. This finding demonstrates that the 4-hour soaking duration resulted in significantly different catch outcomes compared to the 3-hour and 2-hour durations, but no significant difference was observed between the 3-hour and 2-hour treatments.
