Ecological factors related to the distribution of Bankia gouldi Bartsch in Chesapeake Bay

Organisms were collected on test panels, six inch lengths of dressed two by four inch pine, suspended in the water in a vertical position as described by Turner (1947). The panels were usually located at some convenient structure such as a dock-piling or sea-wall. Except where otherwise indicated by the data, the samples were collected from each station once a month between May 1950 and May 1953. During the three year period, seven hundred and nineteen panels were submerged in Chesapeake Bay. Approximately 14,000 organisms were encountered on these panels of which 20% or approximately 3,000 organisms could be identified from the dried pallets. Preliminary notes on the extent of fouling were made in the field after which the samples were removed to the laboratory for further study.
