The study conducted on the Rainbow trout (Oncorhynchus mykiss) culture shows various necessities for its growth. During the study, the necessities were analyzed and the prominent factors affecting its growth were frequently scrutinized. The very factors were dealt with and the effects made by variations in diet formula, were documented. By increasing the percent value of one of the parameters and decreasing the values of others, had a prominent role in the successful culturing of Rainbow trout. Similarly sample trout fish to which feed was provided in dirty pots and low standard habitat showed a retarded growth and thus lesser trout yield, while the ones provided with encouraging feed and habitat had high yield as expected. Also the water quality was brought into consideration and its impact was observed to be vital on trout growth. Two samples were differently analyzed providing high and low standard water qualities. The ones provided with standard water were more successful in growth. Standard water qualities and the proteins were found to be of keen importance in the growth.
