General aspects
Short definition: any area protected (part or all) by law.
Areas managed mainly for:
- Conservation of biodiversity and habitat
- Protect species or populations
- Fishery management
- Scientific knowledge
- Education, recreation and tourism
In the W Mediterranean (mainly from 1980’s):
- Multiple-use and diverse. Most of them to restore fisheries
- Highest number in European waters

3. Marine Reserve effect
Changes undergone by the living components of a marine system as a result of the reduction or elimination of an impact, most commonly fishing
Increase of abundance and mean size
Increase of reproductive potential
Biomass export

9. Lessons from worldwide experience
Contribution to sustainable fisheries
Socio-economic issues are critical. Support of local people
Financial sustainability
Monitoring program:
• Assess management effectiveness
• Adaptive management
