Fish Production through Integration of Livestock

Abstract

Using integrated livestock-fish systems to resolve the environmentally safe manure disposal of feed lot type animal husbandry farms will certainly gain momentum in India with the proliferation of such ventures. Despite the fact that only some 15% of the total nitrogen introduced to the fish sub-system is recovered in the fish yield, these systems are extremely useful environmentally, because over 80% of the nitrogen input “disappears†(volatilizes or is immobilized in the sediment), with only a small amount (not more than 2%) getting to the environment in the drained water of the fishponds. It is likely that fish farming combined with animal husbandry can be developed on large scale in India where small scale rural fish farming already exists.
