TILAPIA FARMING/PRODUCTION SYSTEMS

Tilapia is cultivated in a tremendous diversity of production systems, in ponds, cages, hapas, raceways, concrete tanks, from extensive to super-intensive practices at small-scale and large-scale level, for self-consumption or marketing and even processing purposes. The technology for tilapia farming is well established and tested, ranging in production from 200 kg.ha-1.yr-1 in stocked rice paddies to over 2000 mt.ha.yr-1 in the more intensive tank culture system. Tilapia aquaculture industry produced 14,388 tonnes in 2000 and increased to 19,546 tonnes in 2005; and was based mainly on O. niloticus (Fagbenro and Adebayo, 2005; Ayinla, 2007), cultivated under intensive (commercial) and semi-intensive (artisanal) production systems. Tilapias are suited to low-technology farming systems. This is because of their fast growth rate, efficient use of natural aquatic foods, propensity to consume a variety of supplementary feeds, omnivorous food habits, resistance to disease and handling, ease of reproduction in captivity and tolerance to wide ranges of environmental conditions; and its use to control aquatic microphytes (Fagbenro, 1998, 2001; Fagbenro and Akinbode, 1988).
