This bulletin is the third of a series begun in 1948, presenting detailed data on the commercial fin-fishery of Maryland. A full description of the techniques of collection and tabulation were included in the first bulletin [Publication 69], and inasmuch as identical procedures have been employed throughout the program, further mention of methods is not made.As in past years, records were received on a voluntary basis from approximately 94% of all licensed fishermen. Most of the records were submitted in the form of weekly or monthly summaries.The statistics set forth were derived from records obtained only from licensed commercial fishermen and contain no data pertaining to small unlicensed units of fishing gear, or to the sport fishery.
