Fish Monitoring in the Wadden Sea
A number of long-term (> 10 years) fish monitoring programmes are being conducted in the Wadden Sea. These include stow net and fyke programmes, as well as well as trawls.
The trilateral Expert Group Swimway (EG-Swimway) has proposed a common fish monitoring programme in the trilateral World Heritage Area Wadden Sea under the umbrella of the Trilateral Monitoring and Assessment Programme (TMAP).
Eight well-established and proven monitoring programmes of the three countries were selected as candidates for TMAP fish monitoring.
Candidate monitoring programmes selected for Trilateral Monitoring and Assessment Programme (TMAP) fish monitoring. Data from Alfred Wegener Institute for Polar and Marine Research are protected by a temporary moratorium and therefore comparability discussions are pending. A Lower Saxon stow net fishery 2005 – 2017 is not an ongoing monitoring programme, but the data set is valuable as a baseline (Source: EG-Swimway, 2022).
