Few Signals Displayed Although the recent London Fisheries Po- licing Conference agreed to have pair trawl- ers use the international code signal "T," a red, white, and blue vertically striped flag during daylight, and crossed search lights focused ahead of the vessels at night, few if any pair trawlers display these signals.
