Abstract

In aquaculture practices, the mortality of larval fishes can be reduced by providing them with nutrient rich feeds. Nutritionally balanced fish diet can enhance the growth performance and survival of the fishes (Tom and Van-Nostrand, 1989. In the present study, the experimental fish Amur carp fries (initial weight of 0.03gm) were provided with different artificial feed (corn bran, wheat bran) and natural feed (Daphnia, Earthworm, Spirulina)  as dietary sources to investigate the changes in various biological and chemical parameters such as growth performance, feed utilization and survival rate, length-weight correlation, condition factor and protein percentage in muscle. The experiment of the present study was conducted in the laboratory of Fish Biology and Fishery Science, Department of Zoology, Bhattadev University, Bajali, Assam, India for a period of 3 months (April, May and June, 2023) on 16 fries of Amur carp. The fish with average initial weight about 0.033g were stocked in two different aquarium tanks (136 litre capacity each) each containing 8 fishes. Various water quality parameters like water temperature, pH, dissolved oxygen, total alkalinity, total hardness and free CO2 were monitored during the experimental study The present experimental study revealed that incorporating a mixed diet completes the nutrient requirement for Cyprinus carpio hematopterus  fry rearing. The present study will benefit the aquaculturists by reducing the risk of mortality of  larval rearing of fishes and increasing the total fish production. The results were expressed as mean ± SD and the data were analyzed using One- way ANOVA calculator including Turkey HSD.
