Abstract

Kebumen Regency in Central Java Province is a major shrimp producer area in Indonesia. The shrimp caught in this area include the greasyback shrimp (Metapenaeus ensis) which holds considerable economic value. This research was performed to examine the level of exploitation of greasyback shrimp based on growth, mortality, and exploitation rates. Data were collected from October to December 2024, while a systematic random sampling was used in sampling the carapace length (CL) of greasyback shrimp. The sample size comprised 10% of the total catch, amounting to 391 individuals. The initial CL after being caught (CLc50%) was 3.91 cm with an infinite CL (CL∞) of 9.0 cm. The highest recruitment was estimated to occur in August. The utilization rate of 0.26 indicated that the utilization of greasyback shrimp in Kebumen waters is underexploited. The results of this research can serve as important basis for sustainable fisheries management to maintain the balance of stocks and sustainability of greasyback shrimp in the region.
