Scientific name: Halichoerus grypus (Gray Seal)
Habitat: Bathydemersal Main role: Predator Trophic level: 5
IUCN Red List Assessment:
Diet: Gray seals feed mostly on sandeels, but the diet of harbour seal is more variable with relatively high proportions of gadoids, flatfish and coastal demersal fish such as gobies, bullrout, and dragonets.
Threats: Seals are sensitive to pollution, coastal disturbances, and entanglement in marine debris.
Return to birds and mammals.
Seal is a month-by-month, computer generated data layer following calculations made by the ecosystem simulation (EwE). For more information on how Ecopath-with-Ecosim (EwE) works, please visit our Wiki page or visit the official EwE website at https://ecopath.org.
For detailed information on how the simulation works for the North Sea Edition, we recommend further exploring our research publication called "Combining ecosystem modeling with serious gaming in support of transboundary maritime spatial planning".
For detailed information on how the simulation works for the Baltic Sea Edition, we recommend further exploring our research publication called "Foodweb modeling in the Maritime Spatial Planning Challenge Simulation Platform: Results from the Baltic Sea Region"
