UN9: Understanding stock levels and monitoring supply chains |
Description |
The EO data can be employed to estimate fish stocks by analysing ocean conditions, temperature, and chlorophyll concentrations, helping in making informed decisions on fishing quotas and seasons. Data on water surface temperature, which exhibits a strong correlation with the presence of certain fish species, and ocean colour, characterized by distinct spectral signatures indicating chlorophyll pigments' concentration linked to phytoplankton biomass (the main food source in the sea), can assist in selecting optimal fishing locations. The combination of two fundamental factors—knowing the marine environment and knowing where fishing takes place—can be powerful: leading to more productive, better-managed, and more sustainable fisheries. Financial planners and investors can use this information to identify regions with the potential for profitable fishing operations. |

Main processing steps | Remote sensing data from Sentinel-3 like Sea surface temperature and ocean/sea reflectance can be used to generate easy-to-read maps. These maps can be delivered to fishing companies to have a good idea about the most susceptible regions of fish stocks. As water surface temperature exhibits a strong correlation with the presence of certain fish species, and ocean colour, characterized by distinct spectral signatures indicating chlorophyll pigments' concentration linked to phytoplankton biomass (the main food source in the sea). |
