Abstract

Kutum (Rutilus frisii kutum) is regarded as one of the valuable aquatic species in Southern Caspian Sea. Previous reports have indicated that there are two different forms of this fish in the Caspian Sea, the spring-run and the autumn-run. Despite high importance of availability of knowledge around the subject, there is yet no genetic study carried out on the fish’s population structure. A number of nine MICROSATELLITE loci were employed in the present study to investigate the genetic variation and differentiation between spring- and autumn-run of the species in Anzali Lagoon. For the purpose, genomic DNA from 105 specimens from springand autumn-run kutum from Anzali Lagoon and as well from Khoshkrud spring-run fish were extracted, and PCR amplification performed. A total of 149 alleles were detected at the 9 loci across the 3 populations (Anzali spring- and autumn-runs as well as Khoshkrud springrun). Khoshkrud population exhibited a lower allelic and genetic variation (A=5, Ho=0.406 and He=0.612) than the populations at Anzali Lagoon, and in spite of the higher number of alleles per locus (5.8) as well as higher observed heterozygosities (0.606) in the autumn-run in comparison with the spring-run (5.7, 0.571) in Anzali Lagoon, the differences weren’t found as significant (P³0.05). Both F is value and significant deviation from Hardy–Weinberg Equilibrium (HWE) in all the cases (9 loci× 3 populations) indicated a deficit in HETEROZYGOSITY. The highest population differentiation was found between Anzali spring-run and Khoshkrud run (Fst=0.119, P£0.01) and the lowest (Fst=0.07, P£0.01) between Anzali spring-vs. autumn-run. The highest genetic distance (D=0.337) was observed between Anzali autumn-run and Khoshkrud whereas it was found to be the lowest (D=0.25) between the spring- and the autumn-runs in Anzali. The obtained data suggested that the spring and autumn-runs of kutum in Anzali Lagoon should be considered in the studies and enhancement programmes of this species in the Caspian sea.
