The aquatic proteome refers to the full set of proteins expressed by aquatic organisms, offering a snapshot of their physiological processes. Proteomic research helps understand how aquatic species respond to environmental stresses, such as changes in temperature, salinity, or pollutants. By analyzing protein expression, scientists can identify biomarkers for health, growth, and disease resistance. This knowledge is critical for improving aquaculture management practices, including breeding programs, nutrition strategies, and disease control. A deeper understanding of the aquatic proteome can contribute to more efficient and sustainable aquaculture, enhancing both productivity and the welfare of farmed species.
