Abstract

An understanding of biotic and abiotic factors which affect the metabolic rate, growth and survival of fishes can be applied to the practices of fishery management and this can also be used as a means of assessing the responses of the fishes to environmental conditions. In culture practices there is a possibility of reducing the energy costs to a minimum and achieving food conversion to an optimum level. This can be carried out through an understanding of environmental and biological factors which affect the metabolic rate, with a view to reduce the demands on the system thereby increasing the rate of production. The rate of metabolism is directly or indirectly influenced by biotic (activity, weight, sex, age, oxygen debt, condition, starvation and diet) and abiotic factors (temperature, salinity, oxygen, carbondioxide, ammonia, pH, photoperiod, season and pressure) and among them ambient oxygen, temperature and activity exert the greatest influence on metabolism.
