abstract

  • A simulation model representing the effects of dietary energy/protein (DE/P) ratio, water temperature, and their interaction on channel catfish (Ictalurus punctatus) growth was developed by modifying an existing general bioenergetic model of fish growth. New functional relationships representing the effects of crude protein and DE/P ratio requirements on consumption and assimilation were added. Validation of the new model consisted of simulating a laboratory growth experiment. The simulated effects of 18 different combinations of DE/P ratios and water temperatures were essentially the same as observed experimental effects. Development of fish growth models incorporating interactions of dietary quality factors with water quality factors should parallel the increased levels of experimentation seeking to elucidate these relationships. © 1991.
