Scientific article showing that the effects of social enrichment on fish stress responses vary according to the species studied.

Article following on from the FRCAW report on the slaughter of farmed fish. Ifremer reviews the capacity of fish to feel pain, their legal status, and appropriate slaughter methods. Making pre-slaughter stunning compulsory in France would require investment and an overhaul of the way businesses organize their work, but other countries such as Norway have already done so.

Synthesis of concepts and methods for assessing animal welfare through the study of behavior, illustrated by work on certain "neglected" species (buffalo, camels, donkeys, mules and lumpfish). The authors conclude that there is an extreme lack of balance in the species generally studied in research on animal welfare.

Scientific article showing that the repeated diffusion of bubbles in a tank improved the welfare of rainbow trout. The short-term (~7 weeks) and long-term (~21 weeks) enrichment effects were similar to those observed with more conventional environmental enrichment (provision of plants and shelter). The fish were less aggressive, less fearful and showed enhanced learning abilities.

Report on a survey carried out in Denmark in 2023 to gather information on the national fish welfare system for aquaculture. The Danish authorities take the view that current scientific knowledge is not sufficient to serve as a basis for the creation of a legislative framework for the welfare of farmed fish.

Answer to a question on how long it has taken the Commission and EFSA to prepare the revision of European legislation concerning the "End the Cage Age", a revision which was not fully completed in the end.

Article describing the environmental challenges of livestock farming, along with its impact on animal welfare and global health. The article underlines the need for farming practices to evolve, with animal health and welfare as key contributors to the sustainability of livestock farming.

Article exploring the origins of the concept of animal welfare in European law, starting with the Maastricht Treaty (1992). The scope of the cross-cutting clause in art. 13 of the TFEU (Lisbon Treaty, 2007) codifying respect for animal welfare in Europe may vary from one member state to another.

Scientific article explaining the risks of conflating the concept of animal welfare with that of sustainable farming.Linking them can blur their differences and may result in misguided agricultural political decision-making.

Scientific article showing that the feeding predictability contributes to cognitive enrichment, offering a way to improve the welfare and immune status of rainbow trout.
