Environmental effects of marine Norwegian fish farms

1985

This report is not to be cited without prior reference to the authors

Sedimentation rates under fish farms may be very high, and high

levels of fish stock may lead to harmful accumulation rates of

the nutrient salt ammonia. The environmental effects of the

organic load range from minor changes to heavy pollution, depending

mostly on the hydrography and topography. Fish farms seem

to have a different environmental impact than that of sewage,

and it may be inappropriate to measure their outputs in terms

of Biological Oxygen Demand.
