Adaptations and policies
• Practical adaptations and policies are needed
to:

Harness the opportunities expected from greater
abundances of tuna

Replace the fish lost from degraded coral reefs

Capitalise on the improved conditions for pond
aquaculture

Adaptations for tuna
‘Vessel Days Scheme’ to manage
effort of industrial tuna fleets
Cap and trade provisions of
VDS enable all PNA
members to receive some
benefits during ENSO

Immediate conservation
measures for tuna
• Stopping overfishing of bigeye tuna, and
preventing overfishing of other tuna, will:
 maintain stocks at healthy levels
 make these valuable species more
resilient to climate change
Bigeye tuna
Other adaptations for tuna
• Improve safety at sea for vessels fishing in
the cyclone belt
• Climate-proof infrastructure to prevent
inundation by rising sea levels
Suggested supporting policies
Strengthen national capacity to implement the
VDS
Include implications of climate change in
management objectives of WCPFC
Develop further measures to reduce capture of
bigeye tuna by purse-seine
Require tuna vessels to provide operational-level
catch and effort data to improve tuna models

Provide attractive services to
fleets (wharf facilities, re-fuelling,
provisioning)
Suggested supporting policies
• Strengthen governance of agriculture and mining
practices to prevent soil loss and pollution, to
safeguard fish habitats and water quality
• Apply ‘primary fisheries management’ to coastal
stocks to maintain their potential for replenishment
• Increase access to tuna for the food security
• Promote pond aquaculture
Key investments
 Surveys of best sites for installing inshore FADs
 Programmes to install and maintain FADs
 Identify prime locations for pond aquaculture
 Hatcheries and networks to deliver juveniles
Evaluate merits of micro-credit schemes to develop
fisheries around FADs; expand pond aquaculture;
and scale-up post-harvest processing
Conclusions
• Win-win adaptations are available to reduce
risks and capitalise on opportunities
• Supporting policies are required
• Integrate adaptations and policies into
national strategies and action plans for
climate change
