Economics of fish fingerlings production in outdoor culture system

Abstract

The cost of acquiring a fingerling for stocking had always been haphazardly fixed to the detriment of the fish farmer because the cost of acquisition has no economic consideration of its cost of production.  More often that not the fish farmer pays more far above the cost of production. This paper looks into the economics of producing one fingerling in two separate outdoor culture systems aerated and unaerated. The paper concludes that it is cheaper to produce a fingerling under unaerated system than the aerated one even though highest survival was obtained at stocking density of 250fry/m³ in aerated ponds while stocking density of 1,500 fry/m³ gave the least survival rate in both aerated and unaerated treatments.
