Caught and released: an overview of fishes’ sensitivity to being discarded as a tool to aid pursuing ecosystem-based management (COPE) (39416)

Project Details


One main goal of the project is to provide a catalogue of the survival rates of different species subject to the landing obligation under the Common Fisheries Policy (CFP) regulation seen in relation to the discard ratios of different fisheries.
Another main goal is to obtain survival rates for selected important species and fishing gear.

This information can, in the cause of high survival rates, be used in proposals for exemptions from the landing obligation. Species exempted from the landing obligation can be returned to the ecosystem as discards, and contribute to reproduction and recruitment, and thus productivity of the stock. Landings of unwanted catch may cause unintentionally increase in fishing mortality and unsustainable fishery.

Exemptions from the landing obligation may facilitate the implementation of the CFP, especially for small vessels in the mixed fishery for which there is a mismatch between the size of the deck area and the number of species and size groups in a catch that needs to be kept separately during sorting. Also, exemptions from the landing obligation can improve the economic viability of fisheries as the CFP does not allow landed catch below the minimum conservation reference size to be used directly for human consumption, which mostly limits the utility to low value products.

The project is coordinated by DTU Aqua and is funded by the European Maritime and Fisheries Fund (EMFF) and the Ministry of Environment and Food of Denmark.
