    "The Technical and Information Management Services (TIMS) of the Southeast Fisheries Center (SEFC), National Marine Fisheries Service (NMFS) designed and conducted a survey to estimate the number of billfish caught by the recreational fishery in the western North Atlantic Ocean during the 1 year period, May 1, 1977 to April 30, 1978. The Survey assumed that all fishing done in these waters by recreational fishermen would be done from boats 20-65 feet lon (except Florida where 18 and 19 foot boats were inclued) and registered in an Atlantic or Gulf of Mexico coastal state, Puerto Rico, the U.S. Virgin Islands, or with the Coast Guard as a documented vessel. Wherever possible, boats were eliminated from the population based on propulsion and use codes as reported in the boat registration files. A sample of 56, 241 boats was selected by systematic random sampling from a stratified population of 389,930 boats. Questionnaires requesting billfish and shark catch and effort information were sent to the selected 56,241 registered boat owners on June 8, 1978. Approximately 3 weeks after the first mailing, a second mailing of about 33,200 questionnaires was sent to those people not responding to the first mailing. In august, telephone interviews were conducted with a subsample of the nonrespondents to the mail questionnaire. A brief summary of the results of this survey follows"--Executive summary.
