Length-Weight Relationship of Six Fish Species from Sepang Besar River Estuary, Malaysia

Abstract

Length-weight relationship (LWR) of six fish species from the Sepang Besar River estuary, Peninsular Malaysia were analyzes. A total of 594 individuals belonging to six species namely Arius sagor, Photopectoralis bindus, Plotosus lineatus, Toxotes chatareus, Toxotes jaculatrix, and Thryssa dussumieri collected from April 2014 to February 2015 were measured and weighed. Among them, four species showed positive allometric growth and the other two species showed negative allometric growth. The exponent b value of LWR ranged between 2.94 (Toxotes chatareus) and 3.50 (Photopectoralis bindus). This outcome of the present study has contributed to the knowledge of basic information on the length–weight relationship of six most abundant species in Sepang Besar River estuary which is important for future ecological studies and assist in fishery management.
