Length–weight relationship of the lizardfish Saurida tumbil (Bloch, 1795) from the Visayan Sea, Philippines

Abstract

This study determined the length–weight relationship (LWR) and growth pattern of the lizardfish Saurida tumbil (Bloch, 1795) collected from commercial bottom trawl landings in the Visayan Sea, Philippines. A total of 433 specimens collected between October 2024 and September 2025 were analyzed. Total length ranged from 12.1 to 38.5 cm, while body weight ranged from 14.4 to 517.0 g. The length–weight relationship was estimated using least-squares regression of log-transformed length and weight data. The resulting equation was W = 0.006L³·⁰⁵, with a coefficient of determination (r²) of 0.91, indicating an excellent fit of the regression model. The estimated growth exponent (b = 3.05) did not differ significantly from the theoretical isometric value of 3, indicating isometric growth. These findings provide updated biological information on S. tumbil and serve as a useful reference for biomass estimation, stock assessment, and science-based fisheries management in the Visayan Sea.
