The purpose of this study was to determine the spatial and temporal characteristics of the lobster habitat. This research was carried out from September to December 2021. The research location was deliberately carried out in the waters of the Spelman Strait, Central Buton Regency, the location for catching lobster seeds in sand, mud, and coral rubble habitats. The method for analyzing the similarity of lobster seed species using the Sorensen Similarity Index formula which is based on the presence and absence of a lobster seed species with other species at each station and the long-weight relationship, calculated using the formula W=αLb to determine the equation b<3 or negative allometric. The results showed that spatially and temporally, there were 412 individual lobster seeds in each habitat, namely Panurilus. ornatus and P. versicolor. The highest presence of lobster seeds was found in the mud habitat with 177 individuals, followed by the coral rubble habitat with 127 individuals, and the mud habitat with 106 individuals. 316 individuals of P. ornatus lobster seeds and 94 individuals of P. versicolor. The results of binary index testing for each habitat showed that P. ornatus and P. versicolor were found in all habitats with group A (habitat of rubble) and group B (habitat of mud and sand). habitat characteristics. Spatially and temporally, P. ornatus and P. versicolor in the Spelman Strait showed growth that was negative allometric (b<3), where the increase in length was faster than the increase in weight. The R2 value or determination is close to 100%, where the sand habitat is (92%), the difference is (8%), the mud habitat is (90%), the difference (10%) and the coral rubble habitat (is 91%), the difference is (9%), meaning that the weight growth is affected by the increase in length, while the difference is influenced by the habitat. The existence of P. ornatus and P. versicolor lobster seeds needs to be maintained to maintain the sustainability of lobster seeds in the waters of the Spelman Strait.
