Background: Some environmental enrichment methods, such as occupational enrichment (OE), can improve fish growth, but little is known about its effects on fillet quality. In this study, we evaluated the effects of OE using underwater currents on different aspects of fillet quality and muscle metabolism in rainbow trout (Oncorhynchus mykiss), before and after a handling procedure (fasting). The trout were placed in groups of 30 in separate tanks in three treatments for 30 days: no artificial currents (CON), randomly fired underwater currents (RFC), and continuous underwater currents (CUC).

- The study looked at how underwater currents affect stress in rainbow trout.
- Fish were divided into three groups: no currents, random currents, and constant currents, and were tested for 30 days.
- The group with random currents showed less stress and better energy levels compared to the others, suggesting that currents can help trout feel better when they're being raised.
