Environmental effects of marine Norwegian fish farms
Original version
This report is not to be cited without prior reference to the authorsAbstract
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.
