Length-weight relationship parameters of tropical coral reef fishes in the south China sea

Abstract

The present study reports the length-weight relationship parameters of dominant coral reef fish species in the South China Sea. The specimes were collected by hand-line in the lagoons of five representative coral reefs during June 2013 to September 2018. According to FishBase, this study provides first report on LWR of six studied species and practically available parameters on LWR for three species. The estimated b values ranged between 2.218 (Parapercis millepunctata) to 3.308 (Halichoeres hartzfeldii) and the corresponding a values ranged between 3.98×10-6 (H. hartzfeldii) to 6.00×10-4 (P. millepunctata). In five coral reefs, the means of b was significantly smaller than 3. There was significant negative linear correlation between lga and b.
