Fish experiment: Food the same, but biomass increases

16 marzo 2015

To increase the biomass of fish, contemporary ecological theory predicts that either the amount of food or the quality of the food has to increase. In a recent experiment, researchers doubled the fish biomass under identical food supply and food quality by only controlling how much of total food supply that was channeled to juvenile and adult fish, respectively. The results have major implications for the exploitation (harvest) of fish populations and the coexistence of predatory fish and their prey.
