Comparison of conservation strategies for unionids threatened by zebra mussels (Dreissena polymorpha): periodic cleaning vs quarantine and translocation

摘要: AbstractNative unionid mussel populations have recently declined throughout North America as a result of zebra (Dreissena polymorpha) fouling. Periodic cleaning fouled unionids and followed by translocation been suggested methods for reducing mortality. Leptodea fragilis Potamilus alatus were used to determine survival, recovery energetic stores, accumulation newly settled mussels after replacement in situ. Both species had high L. increased stores cleaning. Elliptio complanata Lampsilis radiata compare conservation strategies mussels. Survival glycogen content evaluate stress induced situ, translocation, cleaning, quarantine, relative the control (never fouled) unionids. New settlement was assessed estimate frequency cleanin...
