A model of fish growth is formalized. The parameters are determined by aquaria experiments with rainbow trout (Salmo gairdneri). From the model the following terms can be found independently: Ingested food, growth, production of ammonia-nitrogen, settable and non-settable faeces, and oxygen consumption. Ingested food is determined as functions of temperature and fish size. The other terms are determined as functions of ingested food, temperature and fish size. The terms are balanced in energy or nitrogen. The model can e.g. be used in connection with product planning in fish farms and as a submodel in aquatic ecosystems.
