Summary

Researchers investigated how rainbow trout adapt their scales at the molecular level when moved from freshwater to saltwater, identifying specific small RNA molecules (microRNAs) that regulate bone metabolism during the transition. This foundational biology work helps explain how fish adapt to changing environments, relevant to aquaculture and to understanding how fish physiology responds to environmental stressors like microplastic exposure.

The DE miRNAs and DE target genes identified in this study might play an important role in regulation of bone metabolism during salinity acclimation, relative genes or pathways could serve as key candidates for further studies to elucidate molecular mechanism of teleost bone metabolism, and help performing salinity acclimation and developing marine culture of salmonid species.
