Length-Weight and Length-Length Relationships of Archer and Puffer Fish Species

Length-weight and length-length relationships are presented for four fish species from the estuaries of south Johore, Peninsular Malaysia. The values of the exponent b in the length-weight relationships (LWRs) W= aL b ranged from 2.97 to 3.44 and length-length relationships (LLRs) TL= aSL b ranged from 0.87 to 0.95. The application of these regressions should be limited to the observed length ranges. The condition factor K was judged to be less important in comparative studies, since this parameter was closely correlated with b. To our knowledge the length-weight and length-length relationships presented herein for both archer fish (Toxotes chatareus and Toxotes jaculatrix) and puffer fish (Lagocephalus wheeleri and Lagocephalus sceleratus) species collected from study area represents the first reference available in Malaysian waters.
