摘要

Total genomic DNA from 30 different specimens of Indian mackerel Rastrelliger kanagurta (Cuvier) and 5 king seer Scomberomorus commerson (Lacepede) was extracted by a simple modified phenol-chloroform protocol. PCR amplification conditions using 10-mer arbitrary primers were optimized. Primers with the same nucleotide sequences produced varying Random amplified polymorphic DNA (RAPD) patterns and those with different sequences generated different banding patterns for the same template in the two commercially important scombroid fishes. Primer OPA 07 (GAAACGGGTG) yielded more polymorphic loci with high reproducibility. Better performance of the primers from Kit A (Operon Technologies, Inc) is attributed to their high G+C content, RAPDs were highly sensitive to the concentrations of primer, MgCl2 and the brand of Taq DNA polymerase enzyme, Random amplified hybridization microsatellites (RAHM) can overcome the inherent shortcomings of RAPDs.
