Abstract
This study was aimed to assess the effect of omega-3 fatty acid and micronutrients on growth, meat quality and health status
of polycultured Cyprinid fish species (Labeo rohita, Cirrhinus mrigala and Catla catla). The proposed fish fingerlings
(8.0±1.5g to 10.0±0.9 g and 7±1.1 to 8±1.6 cm) were polycultured in twelve earthen ponds, for eight months (April -
November 2017). Experimental formulated feed (35% CP) having three concentrations of omega-3 fatty acid (0.3, 0.6 and
0.9%), and two concentration of vitamin C (0.75g/kg and1.5 g/kg) and Vitamin E (300 and 600 mg/g). Fish were fed by 5%
of body weight daily. The experimental feed includes 9% omega-3, 1.5 g/kg Vitamin C and vitamin E 600 mg/g showed
highest weight and length gain, higher survival rate (98%), maximum specific growth rate (1.37%) and minimum FCR as
1.85. The values of condition factor (K) in all fish species were found to be more than 1 which indicated the good health
status. Total plate count (TPC) in fish species statistically varied among various treatments. The moisture, protein and
carbohydrates contents showed significant difference while ash and fat contents showed non-significant differences
statistically. The results of current study suggested that dietary supplementation of omega-3 and micronutrients would
increase fish growth and also improve the fish health status and body composition.
