FISHERIES RESOURCE STATUS OF SPINY LOBSTER PANULIRUS PENICILLATUS IN LABANGKA WATERS, SOUTH SUMBAWA, INDONESIA

Abstract

Labangka waters in the south Sumbawa are potential fishing areas only for pronghorn spiny lobster (Panuliruspenicillatus). The aim is to reveal lobster fisheries management activities. Compilation and analysis data of biological dimensions (lobster) and technological dimension (gillnet) is carried out in Labangka, Sumbawa Regency, during May 15-10 July 2019. Lobster production in 2018 describes the utilization status of 'Lightly Exploited' (44.13%). Analysis of 293 samples of pronghorn spiny lobster showed hypo-allometrc growth patterns. The condition factor of female lobster is greater than male, and tends to decrease along with increasing carapace length/CL (age).The highest CL in the class 60.0-75.0 mm which reached 61.09%, and body weight (BW) dominant in the class 200-300 g as many as 44.03%.Gillnet to catch lobsters is selective, effective and environmentally friendly. This is indicated by the size of lobster worthy of capture (BW>200 g/ind) totaling 74.40% at CL>63 mm/ind.
