From Fish Nutrition- Applied Science for Small Waters

Bio-Energetics - The study of the flow and transformation of energy within a particular system. Bioenergetics is the subject of a field of biochemistry that concerns energy flow and transformation through living systems.


Because fish growth often is limited by food availability, supplemental feeding is a logical tool to improve the condition of fish in small impoundments as the energy cost for bluegill to feed on pellets is small relative to the high caloric intake, which can be 4-5 times greater than those fed natural foods (Schalles and Wissing 1976).


These results indicate that total fish production and production of bluegill were each increased approximately 75 to 80% by supplemental feeding in 19 months after stocking (Schmittou 1967)

Most measurements are in energy (calories).
