Abstract

Grouper is a common species that is found in a variety of habitats; coral and rocky reefs, tide pools, estuaries, mangrove swamps and sandy/mud bottom. The goal of this research was to quantify the influence of oceanographic factors such as sea surface temperature, salinity, tide height, lunar day on the available and species composition of groupers.  The surface temperature ranged from 25,5 to 31.3 0C.  Salinity ranged from 25.3 to 31.2 ppt. The abundance of grouper at south costal of Bulukumba was not significantly correlated with temperature and salinity variation. Grouper caught within set net was significantly different among the four lunar days. Ephinephelus suillus and E. mallabaricus were  most abundant on near shore habitat. The total length of grouper caught  within set net ranged from 5.1 cm to 14.6 cm.  The results indicate clearly that this habitat was important for growth of grouper juvenile. Similarly, management and conservation of these species must be implemented. Key Words: grouper, sea surface temperature,  salinity, tide.
