THE INFLUENCE OF OCEANOGRAPHIC FACTORS ON THE AVAILABLE OF GROUPER (Ephinephelus spp) IN NEAR SHORE HABITAT
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.
