Effects of common inorganic salts on the survival and behavioral characteristics of Limonperna fortunei
摘要
Abstract
Limnoperna fortunei is a large benthic animal.It adheres to the substrate surface by secreting byssus,gradually thickening in layers over the years,leading to biofouling.Therefore,a deep understanding of its environmental tolerance is essential for developing effective biofouling control strategies.Aiming to investigate the effects of different en-vironmental factors on the survival and physiological behaviors of L.fortunei,this study investigated the effects of com-mon inorganic salts on the survival rate,immune enzyme activity,and byssal adhesion characteristics of L.fortunei through controlled laboratory experiments.The results showed that:(1)0.17 mol/L NaCl significantly inhibited the sur-vival rate of L.fortunei,and after 24 h of action,the survival rate was all below 20%,remarkably lower than the control and other treatment groups(P<0.05).(2)In the 0.017 mol/L and 0.17 mol/L NaCl groups,superoxide dismutase(SOD)and catalase(CAT)activities exhibited an initial increase followed by a decrease within 24 hours,with the 0.17 mol/L NaCl group showing a more pronounced effect(P<0.05).The other lower concentration treatment groups showed an increasing trend.(3)When exposed to 0.12 mol/L and 0.17 mol/L NaCl,the byssal adhesion force of L.fortunei attached to natural stone substrates decreased significantly(P<0.05),dropping by approximately 40%after 24 hours.The results of this study can provide data support for the formulation of emergency removal plans for L.fortunei in specific scenarios of water conservancy projects.关键词
