Abstract

Tuna fish (Thunnus albacares) is a fish that has a fairly high economic value and is the dominant catch landed at PPS Nizam Zachman which comes from the WPPNRI 573. Based on the high production results and fishing activities, it is necessary to analyze the utilization level that has been carried out by PPS Nizam Zachman in the WPPNRI 573 for the sustainability of tuna fish (Thunnus albacares). This study aims to determine the CPUE (Catch per Unit Effort), sustainable potential (MSY), utilization level and effort level of tuna fish (Thunnus albacares) landed at PPS Nizam Zachman. This study was conducted on 18 until 30 November 2024. The method used in this study is the Schaefer surplus production method approach. Tuna (Thunnus albacares) were caught using handline fishing gear, purse seines, and tuna longlines. The standard used as the FPI (Fishing Power Index) is the highest CPUE value, namely purse seines. Based on the analysis using the Schaefer model, the intercept value (a) shows 30.864 and the slope (b) is -16.458. The intercept value shows that if there is no fishing effort, the potential for tuna (Thunnus albacares) in WPPNRI 573 available in nature is still 30.864 tons/trip. The MSY catch was 14,469,702 tons, the optimum effort was 938 trips, and the allowable catch was 11,575,762 tons with an average utilization rate of tuna (Thunnus albacares) in WPPNRI 573 landed at PPS Nizam Zachman of 92% with an average effort rate of 106%. This shows that the utilization rate of tuna (Thunnus albacares) in WPPNRI 573 landed at PPS Nizam Zachman is in a dense catch condition.

Abstract

Fishing activities of crab (Portunus pelagicus) on the white sand beach are mostly carried out by traditional fishermen using various equipment. Bubu is the recommended fishing gear for catching crab. This fishing gear is a trap and is passive and is classified as a trap type of fishing gear. One of the determining factors that increases the catch of crab (Portunus pelagicus) is bait. This study aims to determine the effect of using different types of bait and determine the most effective choice of bait in catching crabs that live on the White Sand Beach, Karawang. The method used in this study is the Experimental Method with a Randomized Block Design (RAK). The types of bait used are petek fish, puffer fish and chicken liver. Data analysis used the One-way ANOVA test and continued with the BNT Test. The number of catches obtained during the study was 66 crab (Portunus pelagicus) consisting of salted petek bait (28), salted puffer fish bait (23) and chicken liver bait (15). Based on the analysis of the results of the One-way ANOVA test, a significant value for the type of bait was obtained of 0.000 with a significant value <0.05, so it can be concluded that different types of bait have an effect on the catch of crab (Portunus pelagicus).

Abstract

One of the main problems in the productivity of skipjack tuna (Katsuwonus Pelamis) fishing is overfishing which threatens sustainability. This research was conducted to analyze production activities, utilization levels, and their relationship to the sustainability conditions of skipjack tuna (Katsuwonus Pelamis) originating from the WPPNRI 572 waters which are landed at Oceanic fishery Harbor Nizam Zachman Jakarta. Data obtained from the annual report of Oceanic fishery Harbor Nizam Zachman Jakarta for the last ten years, then the data was processed to obtain CpUE, MSY, JTB, and TP data using the 1954 Schaefer model quantitative descriptive method. Based on the research, data was obtained that the production of skipjack tuna originating from WPPNRI 572 and landed at the Oceanic Fishery Harbor Nizam Zachman Jakarta in the last ten years was 366,677.90 tons with a standard effort of 8.644 trips, a CpUE value of 42,42 tons/trip, an MSY value of 39.208,46 tons/trip, and a maximum JTB value. 31.366,77 tons/trip. Based on this data, it was found that the condition of the skipjack tuna resource originating from WPPNRI 572 was in Fully-exploited status with a condition of 94%.

Abstract

The purpose of this study is to determine the most effective setting time for collapsible crab traps in catching blue swimming crabs (Portunus pelagicus) in the waters of Tanjung Kait, as well as to assess whether the setting time affects the number of crabs caught across three different time periods. The research method used in this study is an experimental method. Experimental research fundamentally aims to test the relationship between cause and effect. This study employs a Randomized Block Design (RBD) with nine repetitions, using three different setting times: morning, noon, and night. The results of this study indicate no significant difference between the three setting times—morning, noon, and night. Although variations in the number of crabs caught at different times were observed, statistical analysis confirms that these differences are not significant. Therefore, blue swimming crab fishers in the waters of Tanjung Kait can use any of these three setting times to achieve effective catches.
