Dualistic Feeding Pattern Of Nile Tilapia Oreochromis Niloticus Rearing Under Different Conditions Of Self-feeding System

The Nile tilapia (Oreochromis niloticus) is one of the most important aquaculture species groups in terms of weight of production in Indonesia, approximately 684.000 t per year in 2012 (Indonesian Ministry of Marine Affairs and Fisheries, 2013). Further research is necessary for the establishment of the culture technology for this species, because knowledge about the physiology and ecology on this fish species is still lacking and there are many obscure points such as proper breeding environment and feeding technology. The self-feeding system delivers food based on the learning ability of fish and it is considered to be a new feeding technique for aquaculture that might be controlled by a biological clock (Alanärä, 1992) and distributed depending on appetite (Amano et al., 2007). These practical studies also revealed that the self-feeding pattern of fish could be changed according to differences in rearing conditions, even in the same species. This study aims to clarify if Nile tilapia has the ability to learn self-feeding under different experimental conditions, indoor and outdoor rooms.
