Abstract

Razor clam, Solen regularis or locally known as "ambal biasa" in Sarawak is one of the famously known seafood in this state that provides subsistence income to the local community. A study was ca rried out on the gonadal development of the razor clams based on the Gonadal Condition Index (GCl). Samples were collected with traditional method and were dissected for sex identification and GCl. This study presents an eight months analysis on the GCl fiom July 2008 to February 2009. Results showed four stages of gonadal development; i) spawning, ii) spent, iii) resting period, iv) gonad development. The mean GCl ranged from 0.000 to 0. 100 for Asajaya Laut while 0.000 to 0. 165 for Buntal. Pearson's con-elation between physico -chemical parameters of water and chlorophyll a with the mean GCl va lue was established. Chlorophyll a and dissolved oxygen (DO) showed weak positive con-elation while temperature, pH, and salinity showed negative con-elation. The outcome of this study will be useful fo r the sustainable razor clams fishery management, future aquaculture, and conservation purposes.
