The life with harmful algae in Norway - management
Abstract
Harmful phytoplankton is a part of the natural, marine flora. The need for management
and mitigation of their occurrence and effects has raised with the increased use and
utilization of the coastal waters. Besides fisheries, fish farming and harvesting/cultivation
of bivalves are activities in Norway, which have experienced problems, including
economic losses, due to harmful algae. Management tools for tackling such problems and
minimize losses are proper site selection of aquaculture installations, regular monitoring of
algae and fast spreading of actual information to the industry and public. In some cases the
information has included a kind of risk assessment and advice on how to adapt to the
situation. When harmful blooms appear we usually put efforts on mapping of the
distribution of the bloom, including its propagation and transport with surface currents.
For new species blooming we have in addition looked for potential unknown toxins
involved with special emphasis on control of organisms exposed to the bloom.
