Salinity is crucial for the survival and performance of aquatic organisms, particularly for species like the northern quahog, which is significant in US coastal aquaculture.
The study aimed to assess how northern quahogs respond at cellular and molecular levels to long-term salinity changes, including effects on survival, hemocyte function, amino acid concentrations, and gene expression.
Results indicated that quahogs survived well under varying salinity levels, showed significant changes in immune functions and amino acid concentrations correlated with salinity, and exhibited distinct gene expressions linked to salinity stress.
The Eastern oyster (Family Ostreidae) is one of the most important fishery and aquaculture species in the U.S. and is a keystone species for coastal reefs.
