| dc.description.abstract | Research on the replacement of Marine Fish Oil (MFO) with vegetable oil has gained much importance due to stagnancy in global production of marine fish oil and increasing market price. The major concern in replacing marine fish oil in aqua feed is by alternative lipid sources which are to economically supply an optimum level of energy with a well balanced level of Essential Fatty Acids (EFA). A 60 days feeding trial was conducted at Fish farm complex of the Fisheries College and Research Institute, Thoothukudi, South India to determine the effect of substituting marine fish oil with vegetable oil such as Palm Oil (PO) on the biogrowth, carcass compositions, water quality characteristics and feed cost of the three species of Indian Major Carps (IMC) viz., the Catla (Catla catla, Hamilton), the Rohu (Labeo rohita, Hamilton) and the Mrigal (Cirrhinus mrigala, Hamilton). Five experimental test diets were formulated to contain a protein level of 30% and varying proportion of fish oil and palm oil as an energy source. The test diets viz. Control (C), Treatment1 (T1), Treatment2 (T2), Treatment3 (T3) and Treatment4 (T4) contained 100% MFO + 0% PO, 75% MFO + 25% PO, 50% MFO + 50% PO, 25% MFO + 75% PO and 0% MFO + 100% PO respectively. The prepared diets were fed to fingerlings of three experimental groups of IMC. Student’s ‘t’ test confirmed that growth performance of all the three species of IMC in terms of mean body weight gain was better in control group than the palm oil based diets. However, no significant difference was occurred between Control (100% MFO + 0% PO) and T1diet (75% MFO + 25% PO) and was also comparable. The growth curve for all the three species fed with different test diets indicated that among the three species, Catla showed slightly higher growth followed by Rohu and Mrigal. Two way ANOVA of the data collected affirmed that among the different test diets, Rohu alone showed significant difference (p<0.03) except Catla and Mrigal. However, among the time bound variations, all the three carp species showed significant difference. Among the different test diets, between all species combination showed significant difference. Similarly, among the time bound variations, between all species combination also showed significant difference except Rohu & Mrigal. Further, among all the carp species also showed significant difference. The present study affirmed that palm oil can effectively replace marine fish oil in the diets of IMC. However, in palm oil inclusion levels of above 25% of dietary lipid, significant reduction in carp growth rate was occurred. The result also showed that carcass qualities of experimental fishes were notcompromised as a result of the use of palm oil in their diets. Water quality of the culture systems did not differ significantly in all the culture tanks. Economic analysis of the formulated test diet of IMC signifies that palm oil inclusion in the diet will reduce cost of production per kg of feed and thereby maximizing the profit in carp farming. Thus, palm oil can be replaced up to 25 % for marine fish oil in the diets of the three species of IMC without affecting the biogrowth parameters and the cost of production per kg of diet will also be reduced than marine fish oil included diets. | en_US |
