Abstract :The main aim of this study was to assess the effect of water depth on the growth performance (length and weight) of table size Indian major carp (Gibelion catla, Labeo rohita, and Cirrhinus mrigala) fishes. Fishes were recorded under different depth (1.20 m, 1.80 m and 2.80 m) for about eight months from February 2016 to September 2016. Water depth was considered as treatment 1 (T1) for 1.20 m, treatment 2 (T2) for 1.80 m and treatment 3 (T3) for 2.80 m, respectively. Randomized Complete Block Design (RCBD) with two replications of each treatment was differentiated at signifi cant level 0.05. Various water quality parameters such as water temperature, dissolve oxygen, transparency, and pH were also recorded.
