- Methods of ensuring sustainable fishing
- Restrict seasons
- Allows breeding / recovery of fish stocks during restricted seasons
- Restrict location
- Allows refuge for breeding
- Restriction by method (e.g. pole and line, minimum mesh size, etc.)
- Reduces catch size
- Reduces impact on non-target species (only target species caught)
- Allows small fish to escape
- Restriction by fish size
- Allows fish time to reach reproductive maturity
- Impose quotas / restriction on number of boats
- Reduces fishing intensity and catch size
- Inspections / law enforcement
- Patrolling, satellite tracking, etc.
- But may be difficult because...
- Policing difficult in large expanses of territorial water
- International waters not subject to restrictions
- Fines imposed for illegal catches are difficult to collect
- Illegal poaching
- Dumping of illegal catch before inspection
- Restrict seasons
