Abstract

Our riverine system, especially the torrential streams and rivers originating in the Western Ghats are known to have variety of ornamental fishes. Except for traditional taxonomic description we have little information on these species, their ecology, biology, life habits, life history and population structure. There is large scale depletion of habitats due to anthropogenic factors which affect the ecosystems of these streams. At the same time, a growing trade in ornamental fish resulting in the exploitation of the resources from the wild stock threatening their existence. On account of this, Government of Kerala State has promulgated a ban on the capture from wild of one of the species Puntius denisonii (Day) during its peek breeding season. The importance of learning more about the species such as P. denisonii and its associated species has motivated me to take-up the present study, the subject of this thesis entitled “Population genetic structure of indigenous ornamental teleosts, Puntius denisonii and Puntius chalakkudiensis from the Western Ghats, India.” My study has brought out some important findings on P. denisonii species complex which I am sure will help towards developing management strategies for conservation and well being of the species.
