Abstract
The 2014 Striped Bass juvenile abundance index was 11.30 and was not significantly higher than the historic average of 8.56. Abundance indices from individual rivers in 2014 varied compared with their respective historic averages, and significantly higher recruitment was observed in the York and Rappahannock rivers. Average recruitment occurred in the James River. Increased catches of young‐of‐the‐year Striped Bass at upriver and downriver auxiliary sites suggest an expansion of Striped Bass nursery grounds in 2014. Similar to Striped Bass, juvenile White Perch abundance indices in 2014 were above the historic average for this species. A weak year class for Atlantic Croaker appears to have occurred in 2014. Average to above‐average indices for forage fishes suggest adequate prey resources for populations of commercial and recreational piscivores in Virginia waters.
