Abstract: An investigation was conducted to know the breeding biology of Vietnamese climbing perch (Anabasrntestudineus), locally known as Koi. Monthly samples were collected from Rupali Fish Hatcheryrnthroughout the period from January to July 2014. Five gross ovarian stages i.e. immature (mean ovarndiameter 0.17±0.05 mm), maturing (mean ova diameter 0.33±0.05 mm), mature (mean ova diameterrn0.63±0.11 mm), ripe (mean ova diameter 0.76±0.08 mm) and regressing (mean ova diameter 0.29±0.09rnmm) were observed. The highest mean GSI value for female and male were 14.91 and 8.33 respectivelyrnin May that indicates the peak breeding season. Size at first maturity for female was approximately 20.5rncm in total length and fecundity was ranged from 50610 to 227378. The relationship between fecundityrnand total length (TL), fecundity and body weight (BW), fecundity and ovary weight (OW) and fecundityrnand ova diameter (OD) were linear. The present study provides the first detailed information about thernbreeding biology of Vietnamese Koi in Bangladesh. Therefore, the results will play a vital role for therninduced breeding, proper management and conservation of this species.
