Growth, Mortality and Recruitment Patterns of Amblyrhynichthys truncatus (Bleeker) in Paya Bungor, Pahang

This paper attempts to determine the growth, mortality I1nd recruitment patterns of A'mblyrhynichthys uuncatus by using a computer-based methoa for the analysis of length-frequency data (ELEFAN I & II). It is shown that this species has an approximate life span of four years with -the fo...
