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

Abstract

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 re- gressions should be limited to the observed length ranges. The condition factor K was judged to be less important in com- parative 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 (Lagocepha- lus wheeleri and Lagocephalus sceleratus) species collected from study area represents the first reference available in Ma- laysian waters.
