Climate and Fisheries Impact Tool
ClimFish is an interactive tool that helps visualize and analyze how climate change affects fisheries and marine ecosystems. It provides data on changing ocean conditions, fish population shifts, and impacts on fishing communities to support better fisheries management and adaptation planning.
Key Features :
- Visualize changes in fish species distribution under different climate scenarios
- Analyze projected impacts on fisheries productivity and catch potential
Climate Scenarios
ClimFish presents multiple climate change scenarios and their projected impacts on marine ecosystems. The tool integrates oceanographic data, species distribution models, and fisheries data to provide comprehensive projections of how fish stocks may respond to changing ocean conditions.
Fisheries Adaptation
As fish populations shift in response to climate change, fishing communities and industries need to adapt. This tool provides insights to support adaptation planning, sustainable fisheries management, and resilience-building strategies for coastal communities.
How to Use This Tool
Select a marine region from the map, choose a climate scenario and timeframe, and explore the projected impacts on fisheries. You can toggle different layers to view specific information such as species distribution shifts, changes in catch potential, and socioeconomic impacts on fishing communities.

Comparison of Maximum Catch Potential
Method Description
This vulnerability analysis assumes that fisheries achieve maximum catch potential when environmental
conditions including fishing pressure conform with the critical threshold of exploited species. The thresholds are currently assessed considering impact related to sea surface temperature (SST) and salinity, assuming habitat suitability for fish production decreases when ambient SST and salinity deviate from the range limit of fish. Changes in SST and salinity are simulated relative to the average conditions (SST = 24 degree C; salinity = 35 ppt) of the Gulf of Guinea during the upwelling season.
