Effects of Salinity on Growth and Expression of Candidate Genes in Lates calcarifer

A sustainable mariculture method is essential for the coastal regions of Bangladesh, given the growing demand and favorable economics of Lates calcarifer (Asian seabass). Hence, this study aims to explore the molecular processes involved in the salinity acclimation of this species, focusing on how these processes impact growth, immunity, and survivability. By examining gene expression in various tissues of Lates calcarifer under high salinity stress, this research will uncover the species' mechanisms of salt tolerance. These findings may enhance survival rates in different salinity conditions and offer practical recommendations for the sustainable production of Lates calcarifer as well as other salt-tolerant species in Bangladesh’s mariculture industry. In a broader sense, given the increasing challenges posed by climate change, including shifting salinity levels in coastal environments, understanding the role of specific candidate genes involved in salinity acclimation in Lates calcarifer is essential for optimizing mariculture practices. This study will address gaps in the understanding of immunity and osmoregulatory gene expression in response to salinity stress, providing a foundation for developing more resilient aquaculture systems in the face of environmental stressors, which could have broader implications for sustainable seafood production worldwide.
