Abstract
This Atlas presents the key results from the Irish groundfish survey programme which is carried out annually in the waters around Ireland, and the Deepwater programme conducted between 2006 and 2009. The various groundfish surveys are described together with the gear used and the areas surveyed. A short note on the biology of each species is given together with their catch length profile and growth curve (size of 1 year olds; two year olds; etc.). The abundance and distribution of the main commercial and non commercial fish species caught on the surveys are mapped, and the catches over time are plotted. Two case studies are used to illustrate the application of survey data.
