Description

Rays and Skates are commonly known as Elasmobranchs, which include, sharks, skates and ray, they differ from other fish in the sea by having a skeletal structure made out of cartilage as opposed to bone.

Diet: Rays and Skates have similar feeding habits as they are both bottom-dwellers.

Threats: They are vulnerable to overfishing and once depleted, populations take a long time to recover. Rays and Skates are slow growing, late to reach maturity and typically have low fecundity, thus the number of individual fish recruited into a population on an annual basis is low. Young Rays and Skates are large enough to get caught as by-catch in trawl nets and dredge gear. Relatively a small proportion will actually reach breeding age.

Metadata

Data Source

Rays and Skates 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 Clyde Marine Region Edition, we recommend further exploring our research publication called "Combining ecosystem modeling with serious gaming in support of transboundary maritime spatial planning".
