Shrimp farmers have been facing complex challenges. Internally, there are the challenges from disease outbreak such as TPD, EHP, AHPND, …; influence of weather condition and climate change; and inconsistent post larvae quality and availability, ... These difficulties combining with low farm gate prices, complicated global market dynamics are creating the biggest difficulties ever for shrimp farmers. With all challenges, success rates and profits of shrimp farmers had been reduced significantly during the past year. As feed costs representing about 50-55% of total production cost in shrimp faming with high stocking densities, many aquafeed companies and shrimp farmers switched from premium feeding programs with high protein feed (45% protein) to medium (40%, 45% protein) and standard feed (40% protein) with lower protein contents with the assumption to reduce feed cost and total production cost thereby enhancing profit in the end. The economic model was applied to evaluate the profits of farmers with different feeding programs in which 200 proofs of performance were collected from the market. These proofs of performance were converted to 50, 60 and 90 days of culture to better visualize the performance of shrimps and estimated profits. According to the result, farmers fed high protein feed showed the best profit after 90 days of culture at about $2.08/kg, whereas lower profits at $1.32/kg and $1.12/kg were observed in farmers fed lower protein feeds. With the utilization of 45% protein feed, farmers could also shorten days of culture to reach the break-even point.
