sustainable fisheries…)- Set-up artificial reefs

2. Tourism

3. Additional energy resources

4. Offshore Aquaculture

5. Bio-Remediation / Bio-Extraction

6. Use of fouling organisms

Key Issues:

1. Multi-use concepts ease MSP2. Multi-use will have a better acceptance for both

stakeholders and would save costs. 3. Multi-Use concepts will have economic benefits

• Quick procedure• Combined EIA• Shared vessels/personal• training• Additional biomass• etc.
