Abstract
This study reports length-weight relationships of yellowfin tuna Thunnus albacares, skipjack tuna Katsuwonus pelamis, yaito tuna Euthynnus yaito, and blue round scad Decapterus maruadsi from Mischief Reef, South China Sea caught by light falling-net fishing method. A total of 311 individuals were sampled in this study. The length-weight relationships of yellowfin tuna, skipjack tuna, yaito tuna and blue round scad can be expressed as W yellowfin = 0.0096×L2.548 (R2 = 0.9243), Wskipjack = 2.7593×L1.4437 (R2 = 0.8468), Wyaito = 0.0079×L3.1983 (R2 = 0.9087), Wblue = 0.0049×L3.3415 (R2 = 0.8924), respectively. To the authors’ best knowledge, this study presents the first references on the length-weight relationships of the collected species in Mischief Reef, South China Sea. Results from the present study will provide biological information to conserve the natural resource of these species in South China Sea.
