Area of Science:

  • Fisheries Science
  • Marine Biology
  • Animal Welfare Science

Background:

  • High discard rates in commercial fisheries contribute to marine ecosystem waste.
  • The European Union's landing obligation incentivizes research into fish discard survival.
  • Existing guidance for discard survival studies lacks focus on animal welfare implementation.

Purpose of the Study:

  • To address the need for integrating animal welfare (AW) regulations into discard survival studies (DSSs).
  • To investigate experimental procedures in DSSs through relevant examples and output results.
  • To align DSS methodologies with current and future AW guidelines, emphasizing the 3R principles.

Main Methods:

  • Review of experimental procedures in discard survival studies.
  • Analysis of output results from DSSs.
  • Application of animal welfare guidelines and the 3R principles (Replacement, Reduction, Refinement) to DSSs.

Main Results:

  • Discard survival studies are at the forefront of fisheries research incorporating animal welfare requirements.
  • There is a recognized gap in the experimental implementation of AW regulations within DSSs.
  • The 3R principles offer a framework for ethically conducting DSSs.

Conclusions:

  • Integrating animal welfare principles into discard survival studies is essential for ethical and compliant research.
  • The 3R principles provide a practical approach to enhance the welfare of fish in experimental settings.
  • This research broadens the application of animal welfare considerations in fisheries science beyond DSSs.
