A 575lb blue marlin tagged in Puerto Rico covered nearly 5,000 nautical miles, crossing the Atlantic, satellite statistics have shown. The fish, tagged during the Club Nautico de San Juan’s annual billfish tournament in September 2011, has recorded the longest diatance for an electronic tag in a marlin. Its long journey won its captors and taggers top place in the first year of the International Game Fish Association’s Great Marlin Race, which saw six tagging events helping to set 23 satellite tags in blue and black marlin in three oceans. “These fish are covering incredible distances,” said Stanford University marine biologist Dr Randy Kochevar. “The data we are collecting through the Great Marlin Race is giving us a new level of insight about where these fish are traveling, and how they are using their open ocean habitat.” Full story here.
