A high level of genetic diversity was observed in Katsuwonus pelamis populations from India ( h = 0·952, ne = 14·3) and Japan ( h = 0·897, ne = 8·9). The log‐likelihood ( G )‐based exact test revealed significant heterogeneity in the distribution of haplotypes between the two populations ( P < 0·01, s . e . = 0·001). This result suggests that the two populations should now be treated as demographically independent and managed separately.
