Abstract
The 2018 Striped Bass juvenile abundance index was 10.72 and was not significantly different than the reference mean of 7.77 from 1980-2009. Abundance indices in the James and York river systems in 2018 were average compared to their individual reference means (1980-2009), whereas abundance was above average in the Rappahannock River. Relatively high catches of young‐of‐the‐year Striped Bass at downriver sites in 2018 suggested Striped Bass were displaced downstream of their typical core nursery areas, likely due to high volumes of freshwater discharge and low salinities before and during the sampling period. Juvenile White Perch abundance indices in 2018 were above historic averages in the James, York and Rappahannock river systems.
