Substitution of animal protein concentration with different levels of dried artemia in diet of Fingerling common carp (Cyprinus carpio)

Abstract

This study was conducted to know the effect of dried on some nutrition of fingerling common carp Cyprinus carpio which were collected from Babylon province to the Laboratory in Saidiya quarter where all proper conditions were provided for fish breeding in order to conduct the experiment. This study included 80 sterilized fish as weight rate ranged between 9 and 12g randomly distributed on 8 pools with capacity of 7.5 L for each (4 treatments with 2 replicates for each) with cultivation intensity of 10 fish/ pool with rate of Bio mass weight ranged between 99 and 100g. The experiment was divided into 4 treatments (diets); the first (T1) considered as a Comparsion and included 100% concentrated animal protein, T2 included 50% dried artemia + 50% concentrated animal protein, T3 included 75% dried artemia + 25% concentrated animal protein, T4 included 100% dried Artemia. These diets were synthesized in the fish laboratory of high studies-College of Agriculture-University of Baghdad. Artemia was involved to lab diets into dried Type, as the artemia was collected in containers as a biomass then dried under 40˚C to prevent denaturation of protein, then samples were mobilized in special bags until using as a dried powder nutrition of fingerlings common carp. The experiment was for 120 days starting from 30/ 10/ 2014 and 5% of body weight (biomass) of fish were fed and weighted each 30 days. The results showed that the diets of fingerlings common carps fed by dried artemia were better than the Comparsion diets. The fingerling fish treatment fed by dried artemia had superiority compared with all other treatments, in which, T2 had the better results where the higher rate of weight and growth of 194.2 g and 38.49 g respectively, and followed by T3 that achieved the higher rate of weight and growth and the differences were significant (p<0.05) of 191.31 g and 35.91 g respectively. Thus, dried artemia can be used as source of animal protein and as partial substitute of animal protein concentrated in diets of fingerling common carp by 50% dried artemia + 50% concentrated animal protein and 75% dried artemia + 25% concentrated animal protein
