Opioid system may flag poor acceptance of plant-based feed in farmed trout

KeAi Communications Co., Ltd.
Peer-Reviewed Publication

Rainbow trout fed a fish-free, plant-based diet from first feeding showed lower food intake and reduced growth compared with fish fed a conventional fishmeal and fish oil diet. Brain responses linked to hedonic control were time-dependent: opioid-system gene expression changes were limited in early fry but became pronounced after long-term exposure (8 months), alongside higher serotonin turnover. The results suggest that plant-based feeds may reduce palatability and that opioid markers could help assess feed acceptance and welfare.
