Abstract:
Population dynamic, distribution and the food sources ofFaunus ater along the semi
enclosed lagoon area of Universiti Malaysia Terengganu were investigated in this
presence study. Population parameters such as asymptotic length (Loo = 60.38), growth
coefficient (K=
0.71) of the von Bertalanffy growth function (VBGF) and the growth
performance index (<p' = 3.41) were analyzed by ELEFAN-1 in the FiSAT software.
Besides, the length-weight relationship shows the strong significant allometric growth of
F. ater. Length converted catch curve method shows the total mortality, natural mortality,
fishing mortality and exploitation rate. On the other hands, distribution of F. ater shows
that amongst all five selected of UMT lagoon stations, there were no significant
difference (P > 0.05) of mean densities (No of ind/m
2
) of F. ater when sampled during
April 2010, but shows a significant difference (p = 0.001 < 0.05) when sampled during
July 2010. The density of F. ater has strongly correlated (P < 0.05) with silt(%), but not
clay- and sand- sediment types. In addition, the density of F. ater and TOC (%) were
increase when the sediment type was clay loam-silt, and tend to decreases when the
sediments types change to sandy form.
