Abstract
The Virginia Institute of Marine Science (VIMS) currently conducts a monthly trawl survey in the three major Virginia rivers and the lower Chesapeake Bay to estimate the abundance of economically important finfish species, particularly at the juvenile stage .. VIM:S has conducted similar trawl surveys in various forms since 1955. Although this represents a 40 year period, variations in sampling design and gear have confounded efforts to produce a meaningful, continuous time series. Such variations include changes in stations occupied, sampling frequency, _vessels, and trawl gears. Much of the trawl survey sampling has been documented (Wojcik and Van Engel 1988a, 1988b, 1988c, 1988d, 1989), although some changes have not.
