Preliminary study on the behavior of Mactra chinensis Philippi
摘要
Abstract
To investigate the ethology in the escaping mechanism of Mactra chinensis Philippi,the effects of size and temperature on their jumping behavior,as well as the effects of sediment,flow velocity,and periodic air expo-sure on their burrowing of M.chinensis Philippi,were examined.The results demonstrated that the movement abil-ity of M.chinensis was significantly correlated with its size and water temperature.Juvenile clams less than 3 mm in size could not jump,while those larger than 5 mm could,and the frequency and height of jumping escalated with the increase of water temperature.The juvenile burrowing ratio of M.chinensis increased over time,with the high-est ratio observed on the fine sand substrate,the lowest on the coarse sand substrate,and intermediate values ob-served on the medium sand substrate.The application of water flow significantly increased the burrowing speed and ratio of juvenile clams;however,a decreased ratio was observed when the water velocity exceeded a certain threshold because the clams failed to maintain stability.Juvenile clams crawled out of the substrate upon tidal ex-posure to air,with a longer exposure time leading to a higher crawling ratio.After exposure,some juveniles floated on the water surface for a period before sinking,and the proportion of floating juveniles advanced with exposure time.This study provides a preliminary understanding of the escaping mechanism of M.chinensis from an etho-logical perspective,providing ideas for solving the problem of proventing M.chinensis Philippi,from escaping.关键词
