Description

Benthic invertebrates are aquatic animals without backbones that dwell on or in the bottom sediments of fresh or salt water. Examples: clams, crayfish, and a wide variety of worms.

Benthic invertebrates is a month-by-month, computer generated data layer following calculations made by the ecosystem simulation (EwE).

Different pressures generate by human activities (noise, bottom disturbance, surface disturbance, artificial substrate) have different, complex effects on marine species in terms of movement, survival and procreation.

Benthic invertebrates are a source of food for a large number of fish (notably flatfish, cod, demersal fish), crabs and seabirds.

Only large benthic invertebrates are caught by all fishing fleets, but mostly by bottom trawl.

In the Eastern Mediterranean Sea there are two groups considered under benthic invertebrates:

• Bivalves
• Gastropod

Data Source

Both Bivalve and Gastropod are a month-by-month, computer generated data layer following calculations made by the ecosystem simulation (EwE). The simplified EwE Eastern Mediterranean model was adjusted for use in the MSP Challenge by Eyal Ofir.
