N2  - Results of an ongoing Cooperative Shark Tagging Program conducted by the National  Marine Fisheries Service (USA) are described. In all, 2459 shortfin mako sharks  (Isurus oxyrinchus) were tagged off the Atlantic coast of North America and in the  Gulf of Mexico in the 28-year period between 1962 and 1989. The sharks were  tagged by volunteer fishers, scientists aboard research vessels, and US Foreign  Fisheries Observers on foreign vessels fishing in US waters. Altogether, 231 recaptures  (9.4% of releases) of these tagged sharks have been reported by fishers from 16 countries.  The maximum time at liberty is 8.2 years, and the maximum straight-line distance between  tag and recapture localities is 2452 nautical miles. One tag was recovered from the  European side of the Mid-Atlantic Ridge. Mako shark distribution and migratory patterns  in relation to water temperature are discussed for the western North Atlantic.
