About the REKREA project

The purpose of the REKREA project is to improve the collection of data about the catches of some of the marine fish stocks which are caught by both recreational and commercial fishermen.

REKREA project—background

Some of the fish species that recreational fishermen fish for in Denmark are also important for the commercial fishing industry. In order to assess the state of a particular fish stock, it is important to know how many fish are being caught by both commercial and recreational fishermen. 

When significant numbers of a particular species of fish are being caught through recreational fishing, it is important to include these catches when assessing the stock size. The number of fish caught by commercial fishermen is known with considerable certainty, while the numbers caught by recreational fishermen is more uncertain. Thus, for some fish stocks today researchers do not have sufficient information at their disposal to assess the state of these stocks. Consequently, the basis for managing a particular stock is not as good as it could be.

Purpose of the REKREA project

All EU countries are required to gather information about catches of certain species of fish by recreational fishermen. In Denmark, we have been doing so since 2009, and today the survey covers cod, eel, salmon, and sea trout. The survey is carried out using online questionnaires. Through the REKREA project, DTU Aqua is collecting additional information from recreational fishermen to supplement and improve the quality of the data in the existing survey. 

The aim is to improve the basis for managing some of the stocks of marine fish which are caught by both recreational and commercial fishermen, and to ensure there will be sufficient fish for everyone in future.

Data collection

Data is collected for the REKREA project by employees from the research institution DTU Aqua who conduct interviews with recreational fishermen in the places where they fish—on board fishing tour boats, in harbours, on landing jetties, and along the coast.

The data primarily covers the following: 

  • coastal fishing, primarily for sea trout, around Funen
  • cod fishing in the Sound (Øresund) 
  • salmon fishing in the Baltic Sea. 

Recreational fishing for the three species is an important part of the combined Danish recreational fishing activities, while the three species are also caught by commercial fishermen.


In 2016-2018, the REKREA project is supported by the European Maritime and Fisheries Fund, which is administered by the Danish Fisheries Agency under Ministry of Foreign Affairs.
