Waste system: Its utility and analyses in aquaculture

Abstract

Importance of nutrient harvesting from liquid wastes through aquaculture production in vertically integrated systems is well established. Though wastewater reuse systems in aquaculture widely differ with respect to degree of pretreatment and its methods which have a direct bearing upon the economic conditions of the end users, the ecological and socio-economic impact analyses exhibited overall positivity. Supremacy of heterotrophic microbial pathway coupled with high fish yield at downstream of the wastewater-fed system testifies the ecological efficiency of wastewater in the conversion of wastes to wealth through aquaculture. Urbanization pressure, improved economic condition and betterment in the health quality standards warranted imposition of different safety standards in wastewater aquaculture and quality of the produce with respect to pathogenic load and contaminants. The present paper discussed the waste systems in aquaculture and their analyses in general.
