Aquaculture and its effects on wild Atlantic salmon populations.

This document is a must read for all concerned with negative effects caused by salmon aquaculture on wild salmonids. The International Council for the Exploration of the Seas (ICES) advises that there is substantial and growing evidence that salmon aquaculture activities can affect wild Atlantic salmon, through the impacts of sea lice as well as farm escapees. Both factors can reduce the productivity of wild salmon populations and there is marked temporal and spatial variability in the magnitude of reported effects.

This document explains in detail how aquaculture can have a varying degree of effect and demonstrates that time period, biomass and environmental factors can change effect.
