Regardless of the reason for intensifying tank production, the result is typically a higher biomass at a given site. This higher biomass may cause an increased risk of negative environmental impacts due to the potential of greater production of waste materials originating from uneaten feed and metabolic waste products. While intensification creates the potential for increased discharges, it also may lead to systems in which effluent treatment is more easily carried out, resulting in substantially lower discharges per unit of biomass production when compared to lower intensity systems.
