DCF (Data Collection Framework): Collection of data of the German recreational fishery (angling) as part of the Data Collection Framework of the EU

Next to the commercial fishery the recreational fishery plays an important role concerning the removal of biomass from fish stocks. For certain species recreational fishery catches can have a significant share of the total landings. In addition to its importance for the scientific stock assessment recreational fishery has particular commercial relevance.

Background and Objective

Since 2003 the Institute of Baltic Sea Fisheries (OF) is collecting recreational fishery data in German marine waters of the North and Baltic Sea. This includes effort and catch per unit of effort (e.g. catch/day) in order to estimate total catch for selected species. The aims of the data collection are to obtain reliable, consistent and comparable catch and effort data of the recreational fishery. This data are to improve the current stock assessment, which up until now depends solely on data from the commercial fishery and fishery-independent research. In consequence, this will allow an improved management in particularly of the cod stock.
