The aim of the project is to increase the knowledge on the most important marine recreational fisheries for selected fish and crustacean species in Sweden, and provide information on recreational catches for the purpose of incorporation into stock assessments.
In 2017 & 2018, the SLU-MRFS (Marine Recreational Fisheries Survey) was carried out as an on-site survey in the Swedish coastal areas bordering ICES SD 23 & 24, corresponding to the southwest and south coast of Skåne.
Recreational catches of Western Baltic Cod by private boat and tourboat were estimated as a result of the SLU-MRFS, and due to the probabilistic survey design it is possible to calculate catches of other species encountered in the survey. The WBC catches have been implented in ICES analytical stock assessment.
The knowledge gained during the SLU-MRFS were used to inform an optimized survey with frequency dependent sampling of catches combined with camera for effort, The CAMS-CS (Camera assisted marina sampling – core sites), implemented in 2019.
In the project LOBSERVE, we explore the potential of citizen science in data collection of the European Lobster. Volunteer lobster fishers performed test fishing outside of the season to attain CPUE and length distributions from a large geographical area, in a survey methodology similar to that of SLUs own lobster survey.
