October 23, 2020 — The Virginia Institute of Marine Science’s annual count of young striped bass once again yielded a number higher than the historic average.
But the significant increase — 13.89 fish per sample, compared to last year’s 9.54 and the historical average of 7.77 from 1980 to 2009 — may be a fluke of bad weather and the pandemic, VIMS cautioned.
The survey has yielded results above that historic average for eight years running. It counts juveniles — typically 1-1/2 to 4 inches long — that will grow to the size fishermen want to catch in three to four years.
The survey is based on what nets haul from 18 sites in the James, York and Rappahannock river watersheds. Its biologists usually draw samples from July to early September, but this year, Tropical Storm Isaias and COVID-19 precautions mean 19% of samples weren’t completed. Other indices suggest juvenile striped bass populations are fairly stable, VIMS said. The Maryland Department of Natural Resources, for instance, reported a below-average count in its 2020 survey, but the pattern of below average Maryland and above average Virginia counts has been seen in 2013, 2016 and 2019.
