The Energy Requirements of Percid Fish in Culturet conditions is essential for the viability of the enterprise. As percid fish species are relatively new in culture, there are no models available to estimate the energy requirement of the cultured fish, which in turn limits the opportunities to calculate the required daily feed allowance. Classical

Behaviour of Percid Fishes in the Wild and Its Relevance for Cultureis a change in behaviour in accordance with a shift in relative costs and benefits of different alternative actions. While a diet of plankton is the most energy efficient for a small percid, with increasing size, larger, more energy rich food types become accessible and more profitable to eat. In co

Now efficient photo-thermal programmes exist and have been used by SMEs in intensive fish farming conditions (water recirculating systems).
