Air bubble curtain improves the welfare of captive rainbow trout fry and fingerlings
Published in 2024
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.
