Machinery feeding development for sustainable aquaculture: Self-feeding system

Demand feeder is slightly different with an automatic feeder, it is altered to the appetite of fish because they can prefer which time they activate the feeder, also it triggered to produce a good growth performance and decrease the feed waste. Alternatively, some studies have been carried out for new method of automatic feeding system. Self-feeding system or previously familiar with the name of demand feeding system, is a system based on the learning ability of fish to activate the feeder and utilizing a feeding rhythm that may be controlled by the biological clock. At the past two decades, the development of self-feeding system is growing rapidly, from database, twenty eight studies with the most relevant data have been collected. The peak of paper published was in year 2000 with the most popular fish species was European sea bass (Dicentrarchus labrax, L.).
