Overview

Analysis shows salinity affects antioxidant and immune functions in Macrobrachium nipponense, highlighting cultivation potential.

Key Points

  • The 96-h LC50 of salinity for 'Taihu No. 3' was identified as 11.841 ppt, indicating specific salinity tolerance levels.
  • Acute and chronic stress elevated antioxidant enzyme activities significantly, confirming their key role in managing oxidative damage.
  • Structural damage occurred at salinity levels of 10 ppt or more, leading to impairments in gill and hepatopancreatic tissues.
  • Chronic exposure to salinity upregulated immune gene expression, demonstrating adaptive mechanisms for saline acclimation.
