摘要：
All Trachurus japonicus, Caranx equula, C. sexfasciatus and Alectis cialis all had a diploid chromosome number of 48. The karotype consisted of all acrocentric chromosomes (no. 1-24) in A. cilialis, but the largest chromosome pair no. 1 was subtelocentric in C. equula and C. sexfasciatus. In T. japonicus the karyotype was different from the other species by consisting of 15 biarmed chromosome pairs (no. 1-15) and 9 acrocentric pairs (no. 16-24). The sex chromosomes cannot be identified in any of the 4 spp. studied. The relationship between karyotype differentiation and species diversity of carangid fishes was discussed.
