Records of white marlin, Makaira albida (Poey), from long-line stations of the Fish and Wildlife Service M/V OREGON indicate a concentration of this species in the Mississippi delta region in midsummer, followed by a gradual dispersal to other parts of the Gulf of Mexico. In
April and May the marlin again move northward. The northward distribution and migration appears limited by the 75° surface isotherm. There is no evidence of correlation of either presence or abundance with depth of water. Some distributional similarities between white marlin and yellowfin
tuna are noted, and a few pertinent literature references mentioned. The need for further study is emphasized.
