Understanding a species' dietary intake is key to understanding its trophic interrelations in addition to population and community dynamics within an ecosystem. Dietary information provides insight into a species' energy consumption (e.g. somatic growth and reproduction), the ecology of the food web and species interactions, such as predation and resource competition. This information can supplement an 'ecosystem-based' approach to fisheries management, by supplementing data and information to multi-species and ecosystem models.
The ICES stomach data portal contains historical and new data from various projects and scientific surveys.
The historical data includes data from fish stomachs collected through the Year of the Stomach project (1981, 1985-86, 1991) from the Greater North Sea and from data collated under the EU Tender MARE/2012/02 which focused on the Baltic Sea Region and specifically Cod.
