(Mote Marine Laboratory has been conducting aerial surveys to estimate manatee populations and distribution since 1985.  This report presents the six years of data collected in these areas from 1985-1990.  The primary objectives were to determine the relative abundance, distribution, seasonality, and habitat requirements for manatees in the bays, gulf and rivers of this study area.  The continuous surveys also provide data necessary to monitor changes in level of use and to detect secondary manatee areas and possible migratory routes.)
