Application of limnology for efficient nutrient utilization in tropical pond aquaculture

Abstract: In most waste-fed systems, water quality degradation ultimately limits net fish yields (FY). Often as fertilization rates increase, inefficient nitrogen utilization together with daytime pHs […]

Effect of Nile tilapia (Oreochromis niloticus) on the ecosystem of aquaculture ponds, and its significance to the trophic cascade hypothesis

Abstract: The trophic cascade hypothesis holds that an increase in fish biomass causes a decline in food organisms of the fish, which cascades down to regulate […]
