The 2022 juvenile Striped Bass abundance index was 7.95 and was not significantly different than the reference mean of 7.77 for the period 1980 to 2009. Abundance indices were average in the York and Rappahannock rivers and below average in the James River in 2022 compared with the river-specific reference means (1980-2009). Relatively low catches of young‐of‐the‐year Striped Bass from sites upriver and downriver of core nursery areas suggest juvenile Striped Bass largely remained within core nursery areas in 2022.
Indices of abundance were also calculated for three additional economically and recreationally important fishes in Virginia waters. Juvenile White Perch abundance indices in 2022 were above historic averages in the York and Rappahannock river systems, but similar to the historic average in the James River. Atlantic Croaker abundance in 2022 was similar to the historic average observed in Virginia waters. In contrast, the abundance index for Spot in 2022 was generally below the historic average in Virginia waters.
