Feeding Calculator is not designed to replace a professional nutritionist. Rather, it is designed to be used as a management tool for producers to more closely monitor the nutritional needs and feed costs of their operation. When used correctly, the program will help shrimp farmers estimate feed inputs correctly. Feed management strategies will be optimizing feed inputs, reducing feed conversion ratios (FCR) and reducing the potential impact on the culture and effluent water. Improvements in FCR have resulted in significant reductions in feed costs and subsequent improvement on the return on investment.
If you experience any technical difficulties or have questions about the program, or you are an expert in aquaculture, please Feedback US. We highly appreciate your cooperation and we thank you in advance for taking the time to share your bright ideas.
