Vertical Patterns in Lake Sturgeon (Acipenser fulvescens) Larval Drift within Two Rivers Directly Connected to Green Bay, Lake Michigan

Figure 7

Number of drifting larval lake sturgeon collected during sampling by net type in the Oconto River in 2013. Box plots illustrate the median and interquartile ranges with jittered grey dots showing the observed larval lake sturgeon catch within each net type. Vertical nets were designed to sample different sections of the vertical water column (Figure 2). D-frame nets represent “traditional” sampling gear designed to sample at the river bottom. Both net types were interspersed across the cross section of the river. Days 3, 4, and 5 were peak drift and occurred from May 24 to May 26, 2013.
