Let Cultivation Projects Limit the Quantity of Nutritional Salts, Bottom Segments And Erosion

The marine biological environment has been destroyed by pollution in many oceans and sea areas.

• Let rehabilitation projects be habitats for fish and other marine life forms:
  In many sea areas rehabilitation projects have been implemented to remove existing polluted bottom masses or to cover these with fresh clean masses. Both these projects cause damage to the marine biological environment and it can take several decades before a new satisfactory marine biological environment has been established. The improvement of the marine biological environment may be carried out in a quicker way through installation of artificial habitats.
• Cofferdams may limit erosion and discharge of nutritional salts through brooks and rivers:
  Grip erosion protection installed in a curve across brook or river mouths may reduce damages. This will reduce the water speed which results in precipitation of eroded masses. The solution will further simplify recycling and use of the eroded masses. The reefs will at the same time act as habitats and breeding locations for fish and other marine life forms and will thereby become excellent fishing places.
• Discharge of industrial salts may be exploited to increase the marine biological environment:
  Many brooks and rivers with public or private outlets produce large discharges of industrial salts and pollute sea and ocean areas. Artificial habitats will improve the marine biological environment which can make use these salts in the areas. Thus areas which today are regarded as destroyed become breeding locations for fish and other marine life forms.
• Bottom segments, among others under sea farms, may be used to improve the marine biological environment:
  Trough installation of artificial habitats under sea farms, the bottom segments may be utilized and thereby increase the production of fish and other sea life in these regions. The production of lobster under shell farms is an interesting alternative.
• Life in sea areas with 'dead water' may be restored :
  In many places the water is "dead" as a result of lack of oxygen. Through installation of artificial habitats the biological environment may be improved and over time make the area habitable for fish and other marine life forms.
• Avoid erosion on the seabed:
  New and loose bottom masses may easily be dragged along by sea currents. It is therefore important to secure these areas with constructions that prevent erosion. Grip erosion protection, Lista Reef and Svenner Reef are suitable for these projects.
