Abstract [English]

To stimulate catch production and wise management patterns, research is carried out on the study of ecological aspects, estimates of population dynamics and exploitation rates of crayfish (Panulirus Spp) in the Spermonde waters of the Makassar Strait.  Based on the COA (Correspondence Analysis) (Ludwig and Reynold, 1988), as well as the analysis of Von Bertalanffy (1938, in Sparre et al., 1989), it was found that the micro-habitat of Panulirus spp., Generally co-exist with massive coral species Alcyonaria (Sarcophyton, Heliophora , and Tubipora), and branching reefs of the Acropora species (Goniopora and Pavona), as well as living with algal grass species of Caulerpa and Halimeda. The growth pattern of Panulirus lobster follows the equation Lt = 46.3561 (1- e -0.1738 (t + 1.7827)), which means that the length decreases at relatively old age. The total mortality coefficient (Z) of population is 0.5066/year, this is relatively the same as the ideal mortality (M) which means optimal utilization, but it is necessary to select catch sizes that are larger than 24 - 27cm (in the range of 34 - 46cm).
