Problem-Based Learning
Identify: What you already
know. What you need to
know. Decide:
How to access new information that may lead to resolution of the problem.
Recommend: Potential resolutions
for the problem.
Objectives
Identify the management challenges for these fisheries case-studies.
Decide what needs to be known to address these management challenges.
Discuss potential solutions to make these fisheries sustainable in the face of climate change.
Context
Science of anthropogenic climate change Established that climate change is occurring and
is human-induced. Impacts of climate change on fisheries
Discussed the socio-ecological, economic, and governance challenges climate change adds to fisheries.
Realized that there are no easy solutions. Case-studies of climate change and
fisheries Apply previous class discussions to work towards
recommendations for improved management.

UK Fishing History
Overfishing
Overcapacity
Bycatch
Identify the management challenges
General climate change projections Increased average
sea temperature 1.5-4oC
Increased sea level 0.18-0.59m
Ocean acidification pH 0.3
Storm intensity/ocean circulation Long-term impacts
uncertain…ice age?
Identify the management challenges
Projections for fish
Finfish distribution shifts Cold-water: cod; herring Warmer-water: sole, red
mullet, seabass Shellfish
Oysters, mussels, scallops
Ocean acidification
Identify the management challenges

Adaptation and UK Fisheries
If you were the manager, what information would you want to know? Abundance and distribution of fish? Surplus production? Minimize what uncertainties? Market drivers? Enforcement funding? Capacity of the fleet? Alternative livelihood options?
How would you get this information?
Decide needed information
Moving forward
How can UK fisheries be sustainable in the face of climate change? Incentivize adaptive approaches? Re-evaluate subsidies? Spatial planning?
Discuss potential solutions

Class Discussion
Commonalities across the case-studies? Barriers? Uncertainties? Solutions?
Unique characteristics of case-studies? What inhibits universal
management approaches?
Objectives
Identify the management challenges for these fisheries case-studies.
Decide what needs to be known to address these management challenges.
Discuss potential solutions to make these fisheries sustainable in the face of climate change.
