A comparative study of Dsogerm2A, Copper Sulfate and Potassium Permanganate on FCR, Rearing Period and Mortality Rate in Rainbow Trout (Oncorhynchus mykiss)

This study was performed in order to study of the effectiveness applying Copper Sulfate, Potassium Permanganate and one of the new antiseptic material namely Desogerm 2A on mortality rate, rearing period and food conversation rate(FCR) of Rainbow Trout (Oncorhynchus mykiss). Total number of 10000 Rainbow Trout with average weight of (21±2 gr) classified to 4 different groups (3 treatments and 1 control group) were exposure to Desogerm2A, Copper Sulfate and Potassium Permanganate. The experimental treatments were immersed with concentration of 20,2,2 (ppm), for one hour every 15 days short time bathing until final weight (255±5 gr) at water temperature around (13.5 ± 0.5 cº). All treatments were analyzed by one-way ANOVA and Duncan test. Therefore, the results suggested the lowest values of FCR and rearing period which were estimated to be 1.3:1 and 160 days, respectively. The value of average mortality rate percentage (0.723±0.036) was related to group1(Desogerm 2A), too. Additionally, the FCR results indicated the significance decrease for treatment group1 in comparison with other group (p<0.05). The results showed a decreased significant outcome of growth periods among treatments and control group. Also, the value of this parameter showed significant difference among treatment groups (p<0.05).
