Analyses of fishery effort in German fishing fleets
Project
Analyses of fishery effort (log-book data and VMS) and its relationship with fishing mortality and population dynamics of fish stocks
The project aims at a better understanding of the relationship between fisheries and population dynamics of fish stocks in order to better predict and justify the necessity of fleet capacity adjustment measures.
Background and Objective
Fischeries are currently regulated via total allowable catches (TACs) and effort managment. It is hoped that effort managment can help to protect fish stocks from overfishing and illegal fishing. Another aim of this project is to evaluate whether there is a balance between sustainable fishing opportunities and the capacity of the German fishing fleets.

Policy, Science, Public
Approach
Each year, relevant information is extracted from German logbook data to conduct analyses on the effort management in European waters. The data are provided to international working groups. Data are also used to address specific questions from the German Ministry of Food and Agriculture regarding fishing activities of the German fleets.
Our Research Questions
- How much effort is utilised by the German fleets in various areas and which gears have been mainly used?
- Does the current effort level lead to overfishing of stocks in mixed fisheries under the assumption of constant catchability?
Preliminary Results
- Advice to BMEL and EU with regard to fishing effort
- Reports of STECF sub-groups on effort management
- ICES mixed fisheries advice
