Abstract

Level of utilization of Rock Lobster (Panulirus ornatus) resources found in Salemo Island waters, Kab. Pangkep South Sulawesi has not yet reached the Maximum Sustainable Yield level (Hasrun.2002), but if it is managed continuously without control over the use of non-environmentally friendly fishing gear it can result in overfishing. Rock Lobster is a resource that can be recovered, but without serious management it can disrupt the sustainability of the stock. Rock Lobster (Panulirus ornatus) is a marine biota that is widely used as a consumption commodity, both for the domestic market and for export needs). High market demand has the potential to reduce stocks in nature due to overfishing This research was conducted on March 1, 2022 – April 30, 2022 on Salemo Island, Kab. Pangkep Province of South Sulawesi. The number of rock lobster measured was all the catches of fishermen. The number of of rock lobster measured was all the catches of the maximum number of fishermen 275. Carapace length (cm) was measured using a vernier caliper with an accuracy of 0.1 cm.. dan Permen Kelautan dan Perikanan No.1 tahun 2015. Carapace length measurement starts from the spine above the eye to the tip of the carapace on the dorsal indentati, (Sparre et al.,1999). The weight of the of rock lobster was weighed using a digital scale with a capacity of 5 kg and an accuracy of 1 gram. Data analysis using the method Elefan I (Electronic Lenght Frequencys Assesment Tool) program FISAT II (Fao-Iclarm Fish Stock Assesment Tool). The results of this study indicate that the population dynamics of pearl rock lobster the first time it is caught is 8.25 cm with maximum carapace length 18.90 cm. Exploitation rate = 0,22/ year with criteria underfishing (E < 0,5) with utilization rate 22 % and allow upgrade up to 20 %.
