Study: Deforestation Depletes Fish Stocks 69
Rambo Tribble (1273454) writes Adding to the well-known fish-killing effects deforestation has in increasing turbidity and temperature in streams, a study published in Nature Communications, (abstract, PDF access), demonstrates deforestation causes a depletion of nutrients in associated lake aquatic ecosystems and, as a consequence, impacted fish stocks. Lead author Andrew Tanentzap is quoted as saying, '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.' This has troubling implications, as 'It's estimated that freshwater fishes make up more than 6% of the world's annual animal protein supplies for humans ...' Additionally, this may have significance in regard to anadromous species, such as salmon, which help power ocean ecosystems. The BBC offers more approachable coverage.

This has actually been studied and when the salmon die they supply a surprising amount of nutrients not only to the streams but to the surrounding forest. As was pointed out by the two other replies to you the dead salmon get eaten by bears, racoons, otters and other critters that then do what a bear does in the surrounding forest. Here's what looks to be a lesson plan on the subject: Fish as Fertilizer: The Impacts of Salmon on Forest Ecosystems [PDF] [buffalo.edu]
