Conservation Of Fish Stocks
- Education → informs fishing communities.
- Closed seasons → allow breeding.
- Protected areas → marine reserves.
- Net/mesh size control → prevent capture of juveniles.
- Quotas & monitoring → regulate harvest levels.
Sustainable Resources
- Defined as resources produced as rapidly as they are removed.
- Examples: forestry with replanting, regulated fisheries.
- Prevents long-term depletion.
Key Points To Remember

- Both local and global cooperation are required.
- Sustainable use ensures resources remain available for future generations.
