Tilapia fish, which is an important object in the field of intensive aquaculture, had been brought to the Fisheries Research Institute. Scientists of the institute conducted research on feeding these fish in local conditions. According to the results of the research, the initial weight of the fish was 171.9 grams, and the fish weighed an average of 558.3 ​​grams in end research. During the 120-day experiment, the average weight gain of fish was 386.5 grams. It has been found that the use of foods produced for carp fish by a local mixed feed manufacturer has a positive effect on fish feeding.
