Toolbox Strengths

1. Local knowledge and governance

2. Adoption of the Precautionary Approach

3. International associations and agreements

4. Fisheries and Aquaculture Carbon footprint

June 10-11, 2010 OECD Workshop, Busan Korea

Toolbox Weaknesses

1. Consultative governance systems, governmental “command and control” subject to lobbying

2. Data deficiencies in ecosystem observations and monitoring

3. Undefined objectives, and targets

4. Difficulties operationalizing the PA

5. Fisheries and aquaculture carbon footprint

Environmental Impacts

1. Warming – increasing heat, rising temperatures

2. Changing ocean salinity, water column stratification, mixing in lakes and oceans

3. Changing Ocean circulation, coastal upwelling changes in timing, latitude

4. Sea level rise, land subsidence

5. Ocean acidification, increased CO2

6. Atmosphere-ocean, land-ocean exchanges

7. Low frequency climate variability patterns

8. Increased frequency of extreme weather

9. Cumulative climate changes lead to “regime shifts”

Toolbox Responses Summary

1. Enhanced ecosystem observation systems

2. Improved science of fish behaviour

3. Protection of vulnerable species components

4. Integrated tracking of water systems

5. Gear shifts

6. Policy shifts

7. Sector dependence analysis

8. Technological innovation

Adaptive Fisheries Management

• Governance Needs

• Integrate all users

• No panacea

• Encourage information exchange at all levels

• Institute real co-management

• New Zealand SeaFIC implementation strategy

Managing Risk and Uncertainty

• Enhanced Ecosystem Observation Systems

• Clarifying Ecosystem Objectives

• Incorporating Risk in Precautionary Measures

• Building resilience in communities

• Establishing Seasonal Management Decision Making

Best Practices and Further Research

• Strategies ▫ Herbivore Aquaculture ▫ Natural solutions ▫ Fishing Gear Shift - Passive gear, spawner

protection, more juvenile fishery emphasis ▫ Technological innovation ▫ Climate change education

• Communities

▫ Renew Role of Governments ▫ Identify Partners ▫ Understand community dependence on F&A
