Length-weight relationship models of two tropical shads,Tenualosa macrura(Bleeker, 1852) andTenualosa toli(Valenciennes, 1847) in the coastal waters of Sarawak, Malaysia

Abstract

Summary This study investigates length‐weight and length‐length relationships of two species of the tropical shads, Tenualosa macrura (Bleeker, 1852) and Tenualosa toli (Valenciennes, 1847) collected from the coastal waters of Sadong (1°30′59.4”N and 110°44′46.4”E) and Sebuyau (1°31′26.8”N and 110°58′05.8”E), Sarawak, Malaysia. The fish were captured using gill nets (mesh size range 5–12 cm) operated by mechanized boat along the coast of Sadong and Sebuyau, Sarawak. Relative growth coefficient (b) was 2.942 and 3.408 for males and females of T. macrura while 2.909 and 3.178 for males and females of T. toli. All LWRs were significant (p < .05) between sexes for both species with the coefficient of determination (R2) ranging from .85 to .99. This report provides the reference of length weight relationship (LWR) models for the two species in their range of distribution.
