Description
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 lower trophic levels by altered consumptive demands. This hypothesis was evaluated by stocking Nile tilapia (Oreochromis niloticus) at densities of 0, 1, 2, or 3 fish/m3 in triplicated 220-m3 ponds near Bangkok, Thailand. All ponds were fertilized with 500 kg chicken manure
