Environmental impacts on
water quality and habitats

Close knowledge gaps on environmental impacts of innovative sea uses

Suggested actions

  • Promote and conduct systematic research on the role of reed beds and harvesting, macroalgae harvesting and cultivation as well as mussel cultivations on local biodiversity and water quality;
  • Assess the consequences for nutrient regeneration and biogeochemical cycling and benthic habitat deterioration arising from increased sedimentation and sediment oxygen uptake by mussel cultivations;
  • Assess the relationship between offshore, attached, living macroalgae stocks and beach cast macroalgae in terms of biomass, density and annual production rates of stocks of attached, living macroalgae to support the derivation of sustainable quantities of beach cast and free-floating algal mats that can be removed;
  • Investigate the cumulative ecological impact of biomanipulation of bivalve populations;
  • Investigate the danger of releasing bioengineered or invasive compounds, bacteria and microalgae into the marine environment on marine habitats and species;
  • Investigate effects on water quality and animal health through analyses and cultivation of microorganisms in bioponds and filters;
  • Investigate the impact of wave installations on the marine environment;
  • Open net cages: further investigate feed supply and efficiency.
