Purpose of management
Activity 2.1: Class views on what is fisheries management?
What is fisheries management?“The application of fisheries management tools to achieve fisheries management objectives”
Why? – without management, fish stocks will be depleted
Management objectives • Ecological• Economic• Social• Cultural
3
Purpose of management
Example management objectives:• Ensure that traditional resource use is preserved and
promoted• Maximise the economic and social benefits of the
fishery• Minimise bycatch• Minimise damage to fishery habitats• Ensure the fishery stock is at or near maximum
sustainable economic yield
Good management – will balance competing objectives while maintaining fisheries sustainability.

Management toolsInput controls – tools that indirectly control catch using
fishing effort restrictions.• Limiting the number of fishers and/or boats (by licences or other means).• Gear restrictions.• Limits on the number of fishing days.• Temporal (e.g. seasonal closures) or spatial closures.
5
Management tools
Output controls – tools that directly restrict catch.• Total allowable catch restrictions (TACs).• Individual transferable quotas (ITQs).• Bag and size limits.

Management tools in actionManagement tool Input or Output What are they used for
Total Allowable Catch (TAC) Output To regulate the amount of fish taken
Fishing licences Input To control the amount of fishing effort
Minimum size limits Output To allow animals to mature and breed before they are caught; maintain spawning stock
Maximum size limits Output To allow large fecund animals to breed; maintain spawning stock; often used for sex changing species
Ban on night fishing Input To protect some species that are vulnerable at night, eg. sleeping parrotfish
Spawning closure Input To protect spawning fish; reduce capture while at a vulnerable stage
Bag limit Output To control how much is caught and ensure catch is shared
Marine Protected Area Input To conserve habitats and species

Local management
Activity 2.2: Spend ~10 mins reading local fisheries management plans provided and identify input and output control measures. Write them down on separate sticky note paper and place on the flip chart under each heading: Input controls & Output controls.

Unit review
• Fisheries management goal is to avoid depleting stocks.
• Fisheries management uses tools to achieve different management objectives.
• Input controls – control fishing effort.
• Output controls – directly control what can be caught.

Local management
15 minute personal review: unit review, students to review main concepts of unit in the course notes, contribute any new words (new to them) to their own personal glossary in the back of their notebook (local language equivalent terms should also be recorded where possible)
