How often should fish be typically fed in isolated raceway systems?

In isolated raceway systems, fish are typically fed 2-4 times daily to ensure optimal growth and health. This feeding frequency is important because fish have high metabolic rates and require regular nourishment to support their growth, reproduction, and overall well-being. Feeding them multiple times a day helps in maintaining consistent nutrient levels and reduces competition among fish, which can be more pronounced if feeding is infrequent. By providing smaller portions several times a day, it also minimizes waste and ensures that more food is consumed by the fish rather than being lost to the environment. This management practice is crucial in raceway systems where conditions can be tightly controlled to achieve the best performance from the fish.
