This research was conducted to analyse the performance of the lobster-fishing industry on the Pangandaran coasts, to analyze the conditions, efforts, and actual production of lobster-fishing activity in Pangandaran and to determine if it is sustainable and optimal, from the bioeconomic Gordon-Schaefer model, and in addition to provide correct input and output on lobster-fishing activity in Pangandaran. The data gathered for this research has been collected from October 2022 to February 2023 through field surveys. Primary and secondary data furthermore processed through the descriptive-quantitative method of analysis were used.

The result of this research shows that 2020 was the best year for lobster-catching activity in Pangandaran. The species with the highest number of captured specimens was the spiny lobster (Panulirus homarus). The sustainable production catches (MSY) of this type of lobster is 7,423 kg with the catching trip (MSY) of 336,142 trips. The highest efficiency was obtained on MEY condition with 331,215 trips (MEY) and the catches (MEY) are 7,423 kg. The lowest efficiency was obtained on open access conditions, with trip estimated 662,429 trips, which resulted in 428 kg of lobster catches (OA). The optimum profit from the lobster fishing in Pangandaran on MEY condition generated 51,261.37 USD of profit, whilst on maximum sustainable condition MSY generated around 51,118.36 USD of profit.
