This simulation model employs a combination of Ecopath with Ecosim (EwE) and Mass-balance Ecological Model (MEL) methodologies to study the intricate dynamics of cod populations within marine ecosystems. It incorporates trophic interactions, fishing pressure, environmental factors, and spatial considerations to provide insights into the resilience and sustainability of cod stocks. The model enables scenario testing for assessing the effects of various management strategies on cod populations, contributing valuable information for evidence-based fisheries management and conservation efforts.

Description

Habitat: Benthopelagic
Main role: Predator
Trophic level: 4,4

Diet: Juvenile cod are pelagic and feed mainly on copepods. At a size of approximately 7 cm they adopt a demersal way of life with a diet that initially comprised of crustaceans. As they grow, bigger fish become increasingly important as prey.

Threats: Highly commercial and vulnerable (IUCN red list). Cod is a highly fished top predator, which has seen several stock collapses in the 1990s around the world due to overfishing. In the North Sea cod stocks seem to be slowly recovering. Cod are also very sensitive to fluctuations in temperature.

MSP Challenge

Cod 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.

Cod are caught by all fishing fleets, but mostly by bottom trawl.

Information

In the North Sea, several species of cod can be found. The most common and important cod species in the North Sea is the Atlantic Cod (Gadus morhua). This cod species is the most studied and commercially significant cod species in the North Sea, and it plays a crucial role in the region's fisheries.
