Measuring burst movements of smallmouth bass（Micropterus dolomieu）in Lake Kizaki, Japan, usingmicro-acceleration data loggers

This study used micro-acceleration data loggers to measure burst movements, such as feeding behavior, of smallmouth bass（Micropterus dolomieu）. Data loggers were attached to the dorsal side of seven bass released into Lake Kizaki, Japan, during summer 2007Ȃ2008. From 220.7 total hours of data, the burst movement rate was 0.7 ± 0.3 events/hour（mean ± s.d.）（range: 0.4Ȃ1.1 events/hour）. All bass showed burst movements during both daytime and nighttime, but four fish had higher event rates during the day. For two individuals, the mean event depth was significantly deeper during the daytime than the nighttime. -- Keywords : Invasions ; Fish behavior ; Bio-logging ; Micro-acceleration data logger.
