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

Figure 6

The number of larval lake sturgeon captured while drifting from upstream spawning sites in the Oconto River during the spring of 2013. Box plots illustrate the median and interquartile ranges with all catch data within the 4 vertical nets set in 4 different locations presented as jittered dots. The y-axis is presented in the log scale adhering to the statistical analysis used and the non-normal distribution of catch. Larvae were collected using 4 nets specifically designed to sample the entire water column (Figure 2). Nets were deployed equally across the rivers’ cross section with nets 2 and 3 sampled the center of the river channel. Net section 1 was the net bottom, and net section 4 was at the water surface.
