Abstract: The cultivation of largemouth bass (Micropterus salmoides) fry is a crucial phase for successful aquaculture. Tradi-
tional rearing methods often face challenges such as slow growth rates, weak disease resistance, and low survival rates. With
the development of facility-based fisheries, controlled aquaculture environments have significantly enhanced production effi-
ciency. However, research remains insufficient regarding the impacts of environmental factors on the growth and health of M.
salmoides juveniles in industrialized seedling rearing systems. To improve survival rates and growth performance during fry
cultivation, this study investigates the effects of different flow velocities and photoperiods on the growth performance, digest-
ive enzyme function, and antioxidant capacity of M. salmoides fry. In the present study, healthy M. salmoides (0.53±0.08) g
