Abstract: This research was conducted to determine the effects of different stocking densities on the growth, survival, and water quality parameters of Puntius sophore larvae. There were three stocking densities groups marked as T1, T2 and T3, each having three replications. The larvae of experimental fish were reared in metallic trays at a stocking density of 300 (T1), 400 (T2) and 500 (T3) individuals/m³ for 21 days. The percent length gain, weight gain and SGR (%/day), health condition, survival rate of larvae of all three treatments were determined. The water temperature was recorded 25 to 27.50ºC during experimental period. Among the groups, T2 having 400 larvae/m³ showed comparatively better result in terms of percent length gain (268.19%), health condition (47.11%), and survival rate (78.00%). Therefore, the stocking density of T2 is recommended for the rearing of the larvae of jat punti fish for profitable and sustainable aquaculture considering the economic aspect. Further study and research would bring necessary improvements in the larval rearing techniques (eco-friendly) of jat punti to face the challenge of food crisis and meet the financial benefits.
