Pakistan Fish Farmers Should Know the Importance of Fish Feed
Before designing a formula, fish farmers must clarify the fish’s type and growth stage to be raised to determine the level of nutrients such as protein and energy in the feed. It is necessary to meet the protein needs of fish growth and to make the ratio of energy and protein moderate.
Too high and too low energy-to-protein ratios are not conducive to fish growth. Fish farmers should consider the relationship between the nutritional level of the feed and the test weight when designing a formula. It is necessary to ensure that the fish can absorb sufficient nutrients and make them feel full. Fish mainly use protein as an energy source, and the utilization rate of fat and sugar is low, so the demand for protein is higher than that of livestock and poultry. Different stages of fish growth have specific requirements for various nutrients. For example, the protein content of juvenile carp feed is 41% to 43%, fingerling 37% to 42%, and adult fish is 28% to 32%.
