title: Effect of dietary Spirulina level on growth and chemical composition of carcass in rohu, Labeo rohita (Hamilton).
abstract: An experiment was conducted in three different tanks for 45 days (T1, T2 and T3) to investigate the effect of dietary Spirulina level on growth and chemical composition of carcass in rohu, Labeo rohita. A diet having de-oiled rice bran(30%), rice polish (15%), de-oiled mustard oil cake(25%), Soya bean oil cake(10%) and de-oiled groundnut cake(20%) was provided to the control (i.e. 100% formulated feed), whereas in T2 95% formulated feed with 5% Spirulina and in T3 90% formulated feed with 10% Spirulina. Data were analysed with ANOVA (P < 0.05) and found significant. There was significant difference in the average final weight of the fish among treatments with highest in the T3 (11.28g) followed by T2 (8.32g) and T1 (7.51g). The higher SGR was recorded in T3 (2.17) followed by T2 (1.52) and T1 (1.28). There was significant difference in the average carcass composition of the fish among treatments with highest level in T3 followed by T2 and T1.
