Unformatted text preview: s for blue marlin, the taxonomy of sailfish has been problematic: • Morrow & Harbo (1969) – single circumtropical species • Nakamura (1985) – two species based on morphology • RFLP of mtDNA from 56 Atlantic & 33 IndoPacific fish • Higher haplotype diversity in Atlantic fish • Accounted for by presence of two distinct groups of haplotypes, only one of which appeared in Indo-Pacific fish
– These two groups were separated by 3 restriction site differences, and had nucleotide divergence of 0.65% • In contrast to blue marlin, the ubiquitous sailfish haplotypes were not found in high number among Atlantic fish • Only two haplotypes were shared between oceans, accounting for 76% of Indo-Pacifi...
