Abstract

In order to reveal the acute toxicity and physiological changes of Babylonia areolata in response to stresses of low salinity and high salinity, the salinity of 30 was set up as the control group, and the salinity of 15, 20, 25, 35 and 40 were set up as test groups. The results showed that both the test dose and test time were found to have a significant effect on the activity of digestive enzymes (P < 0.05). Compared with the control group, subject to salinity stress: 1) after cultured for 96 h in both low and high salinity water, Babylonia areolata showed slow movement and turned its back up gradually. 2) With the extension of time, the activity of digestive enzymes in each salinity treatment increased first and then decreased. 3) Low salinity had higher influence on the activity of digestive enzymes than high salinity. 4) Among the three digestive enzymes, protease activity > amylase activity > lipase activity. It was observed that the salinity in water could cause a stress response on Babylonia areolata. This study provides a reference for the culture of Babylonia areolata and other shellfish salinity stress experiments.

Key words： Babylonia areolata; salinity; digestive enzymes
