About this tool
How will a warmer, fresher or saltier sea change the catch?
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.
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.
Key Features
- Visualize changes in fish species distribution under different climate scenarios
- Analyze projected impacts on fisheries productivity and catch potential
