水流速对福寿螺生长及摄食率的影响
Effects of flow velocity on growth and feeding of Pomacea canaliculata
摘要
Abstract
[Aim]To investigate the growth and feeding behavior of Pomacea canaliculata under different flow velocity conditions and provide guidance for P.canaliculata control in flowing water.[Method]Indoor simulation experiments were conducted to meas-ure and analyze the shell height,body weight,specific growth rate,and maximum ration level of P.canaliculata under flow veloci-ties of 3.8 cm·s-1,7.7 cm·s-1and no flow velocity.[Result]The average shell height of P.canaliculata showed significant differ-ences under different flow velocity conditions(P<0.05),while the average body weight of P.canaliculata did not show significant difference(P>0.05).Under a flow velocity of 3.8 cm/s,the shell height growth rate,body weight growth rate,and specific growth rate were higher than those under 7.7 cm·s-1and no flow velocity conditions.However,the shell height growth rate did not show a significant difference(P>0.05),while the body weight growth rate and specific growth rate showed significant difference(P<0.05).The total mortality rate of P.canaliculate under the three flow velocities was 25.6%.Specifically,the mortality rate under a flow ve-locity of 3.8 cm·s-1 was 30.0%,while the mortality rates under 7.7 cm·s-1 and no flow velocity conditions were both 23.3%.The mortality rates under different flow velocity conditions did not show significant differences(P>0.05).The maximum ration level of P.canaliculata under the flow velocity of 7.7 cm·s-1 was significantly higher than that under 3.8 cm·s-1(P<0.05),while the maxi-mum ration level under no flow velocity condition was between the two and did not show significant differences with either of them(P>0.05).[Conclusion]Appropriate flow velocities promote the growth of P.canaliculata,but when the flow velocity continues to in-crease,it restricts the growth of P.canaliculata and significantly increases the maximum ration level.关键词
