Abstract
    Genetic diversity of seahorse species was studied using 12 polymorphic microsatellite DNA loci in the yellow seahorse Hippocampus kuda and the three-spotted seahorse H. trimaculatus from samples collected along the east and west coasts of India. Cross-species microsatellite loci amplification in populations of Indian seahorses showed significant numbers of private alleles associated with site-specific populations, which could be used for population genetic studies and management of species for conservation. Significant genotype heterogeneity indicated that the samples are not from the same gene pool, and that physical barriers exist which inhibit breeding between populations. The identified microsatellite loci can be further utilized in fine-scale population structure analysis of seahorses.
