Effect of Insect Meals on the Growth Efficiency, Survival and Total Carotenoid Content of an Ornamental Fish Xiphophorus maculatus (Gunther, 1866)

To evaluate the effects of three non-conventional insects (cricket, grasshopper and mealworm) commercial diet (control) on growth, survival total carotenoid content ornamental fish, platy (Xiphophorus maculatus), a feeding trial was conducted in Zoology laboratory, Vidyasagar College, West Bengal, India, between November 2021 May 2022. A 250 juveniles (0.04±0.002 gm) were stocked 12 glass aquariums with 20 fishes for each experimental feed set. Each made per triplicate. The growth efficiency parameters fish terms weight gain percentage, specific rate (SGR), conversion ratio (FCR) measured at end study period. Protein percent is significantly higher mealworm (46±0.58) then (42.50±0.29). Final fed sets (2.134gm±0.008) lower meal (0.827gm±0.003). lowest FCR found (0.458±0.002) best values cricket (0.280±0.001). Higher value SGR obtained (2.209±0.002) (1.683±0.002). Mean percentage 90% 55% diet. Carotenoid body (9.23μg/g±0.071), while observed (0.47μg/g±0.001). Present shows that insect diets better than diet, but to increase X. maculatus.
