Publication Description :
Biological aspects including size at sexual maturity, breeding season and condition factor of Amblypharyngodon mola was studied in the Payra River, southern Bangladesh during February 2016-January 2017. All specimens were sexed and standard length (SL), body weight (BW) and gonad weight (GW) were measured. The gonadosomatic index (GSI) increased with the body size, however; the GSI rose sharply at 4.1 cm SL indicating the size at sexual maturity of A. mola. Monthly GSI was higher (average value > 8.0) during April to July with a peak in May, indicating this was the main breeding season. Fulton's condition factor by months and SLs varied in both sexes and was attributed to variations in GSI with maturity. The findings of this study will be useful for the management and conservation of this important fishery in Bangladesh and neighboring countries.
