Salinity stress responses in Slipper cupped oyster Crassostrea iredalei from Setiu Wetlands, Terengganu, Malaysia

Aim: The present study investigated some important functional responses to salinity stress in Slipper cupped oyster Crassostrea iredalei from Setiu Wetlands, Terengganu, Malaysia. Methodology: Slipper cupped oysters were subjected to different salinities of 7,14, 28 and 35 ppt for 2 weeks. Total hae...

Description
Summary:Aim: The present study investigated some important functional responses to salinity stress in Slipper cupped oyster Crassostrea iredalei from Setiu Wetlands, Terengganu, Malaysia. Methodology: Slipper cupped oysters were subjected to different salinities of 7,14, 28 and 35 ppt for 2 weeks. Total haemocyte count (THC), phagocytic activity, ionic absorption, total protein concentration (TPC), superoxide dismutase activity (SOD) and histological changes of the oyster tissues were determined after 2 weeks of experiment. Results: THC significantly decreased at 7 ppt but increased at 35 ppt (p
