2005. Dynamics and extent of larval lake sturgeon (Acipenser fulvescens) drift

Lake sturgeon larval drift is not uniform in time or space and subsequent efforts to determine the relative abundance have suffered because of the lack of information during this early life history period. The purpose of this study was to obtain information about the early life history of lake sturgeon, determine the extent and duration of lake sturgeon larval drift, and examine this relationship to water flow and temperature in the Upper Black River, Michigan. This study also compares the results of other studies to further evaluate the dispersion of larvae. Larval production was quantified using drift nets anchored to the stream bottom from May to June in 2000
