Roles of ponds in integrated agriculture-aquaculture systems

Abstract

The effects of adding an aquaculture pond to existing farming operations on nutrient use efficiency and productivity were explored. Ponds can be used to cycle nutrients from agricultural by-products was similar to that of ponds receiving formulated pellets. The largest fraction of the nutrients fed to ponds accumulated in the sediment. Pond sediments were rich in nitrogen and potassium, but only contained small amounts of soluble reactive phosphorous.
