| Abstract: | This study provides the first biological information on a small freshwater benthic fish species Odontobutis sinensis (Wu, Chen & Chong, 2002) from Liangzi Lake, China. The length‐weight relationship was BW = 0.0080TL3.23. The male : female sex ratio was 1.56 : 1. Based on the gonadosomatic index (GSI), the spawning season is from April to June. Females first matured at 7.90 cm total length (TL). Absolute fecundity varied from 346 to 2588 eggs. Main food items consisted of crustaceans and smaller fishes. |
