The researchers conducted an experiment to develop a low-cost diet for farming giant freshwater prawns in Bangladesh. They tested different diets on prawns in ponds and found that a specific diet led to higher prawn weight gain, better feed conversion, and higher survival rates compared to other diets. This diet also resulted in the highest prawn production and net profit. The recommended diet includes fish meal, meat and bone meal, mustard oilcake, sesame meal, rice bran, molasses, and vitamin-mineral premixes.
