Aquaculture & Forests
Category:UpdatesIn a recent study published in Nature Communications it has been suggested that deforestation is reducing the amount of leaf litter falling into rivers and lakes, resulting in less food being available to fish.
Lead author Andrew Tanentzap from the University of Cambridge’s Department of Plant Sciences said “We found fish that had almost 70% of their biomass made from carbon that came from trees and leaves instead of aquatic food chain sources. While plankton raised on algal carbon is more nutritious, organic carbon from trees washed into lakes is a hugely important food source for freshwater fish, bolstering their diet to ensure good size and strength.”
Dr Tanentzap observed: “Where you have more dissolved forest matter you have more bacteria, more bacteria equals more zooplankton. Areas with the most zooplankton had the largest, fattest fish.”
