Genetic stock structure analysis of two seahorse species from the south east and south west coasts of India (37 samples of Hippocampus kuda and 39 samples of Hippocampus trimaculatus from Kollam (Kerala) and Mandapam (Tamil Nadu)) was carried out through sequence variation analysis of a 350 bp cytochrome b fragment of mitochondrial DNA. This was taken up to support the breeding and restocking programme of these species in natural habitats for conservation purpose. The occurrence of strong genetic subdivision among the samples, detected by the analysis of molecular variance (AMOVA), and significant I broken vertical bar(ST) values indicated that stocks of both the species in the two Indian coasts are distinct. The findings of the present study have important implications for conservation and management of these two species and we recommend stock-specific, breeding assisted sea-ranching programme for H. kuda and H. trimaculatus along the Indian coasts.
