Abstract

Sustainability is one of the essential issues in utilizing lobster in the coastal waters of Ayah, Kebumen Regency. Its management requires information on growth parameters and the utilization status of lobster. This study examines the growth parameters and utilization status of ornate spiny lobster (Panulirus ornatus) in the Ayah’s water. The study was conducted from November 2020 to January 2021. Lobster growth parameters were analyzed by distribution frequency of carapace length using the ELEFAN I method. Utilization status was estimated using spawning ratio based on carapace length data (LB-SPR). The results showed that the growth rate of males and females lobster was 0.37/year and 0.32/year, respectively. In addition, the asymptotic length was 145.70 mm in male lobsters and 143.33 mm in female lobsters. The exploitation rate is 0.41-0.48. The estimated spawning ratio is 29.59%, which means that it is still sustainable and below the optimum point.

Abstract

The monthly fluctuation of fish catch is closely related to the presence of fish or the fishing season. Information about the fishing season is important to improve the efficiency and effectiveness of fishing carried out by fishermen. Skipjack and longtail tuna are important catches landed by fishermen in Palabuhanratu fishing port, with fishing grounds in the waters around Palabuhanratu. This study aims to describe the dynamics of the catch and the effort to catch skipjack tuna and longtail tuna that land their fish in the Palabuhanratu fishing port and determine the fishing season. The data used is the Palabuhanratu fishing port fisheries statistical data for the 2015-2019 period. Data analysis used catch per unit effort (CPUE) analysis and moving average method. The results showed that the CPUE value of skipjack tuna fluctuates tends to increase by 0,009 tons per trip in 2016 and reaches the highest in 2017 which is around 3,068 tons per trip. The CPUE value of longtail tuna tends to increase from 0,021 tons per trip in 2015 to 0,266 tons per trip in 2019. The skipjack tuna fishing season in Palabuhanratu Waters occurs in March, July to November, while the longtail tuna fishing season occurs from July to November. Keywords: Longtail tuna, fishing season index, moving average model, Palabuhanratu, skipjack tuna
