Abstract
Summary Objective: Improve our understanding of population biology and ecology for key species of commercial (e.g. cod, plaice, sole), recreational (e.g. bass) and conservation (e.g. skates and rays) interest. Specifically, relationships between fish population sub-units in spawning areas, on nursery grounds and on feeding grounds, how these vary year-on-year, and the contribution of the environment to such variation. Key Customer Purpose: Provide the biological knowledge necessary to improve the management of fish populations into the future against a broad range of policy objectives.
