Abstract

To investigate the present geographical distribution and artificial breeding success of Puntius sarana data were collected from the fishermen of four selected open waterbodies (the Old Brahmaputra river of Mymensingh, the Kangsha river of Netrokona, the Sukhair Haor of Sunamganj and the Boira haor of Kishorganj district), fish consumers of four selected markets adjacent to the four selected open waterbodies and from the ten fish hatcheries of Mymensingh district region. The result of annual catches from four selected sites showed that the highest number of P. sarana were caught from the Sukhair haor followed by Boira haor, the .Kangsha and the Old Brahmaputra river. The fish market survey showed that the mean number of observation per person was highest in the Sukhair haor followed by the Boira haor, the Kangsha and the Old Brahmaputra river. To know the occurrences of artificial propagation, the survey was conducted among ten hatcheries and found that four hatcheries practiced artificial propagation but their average P. sarana fry production was very negligible (8.75%) compared to the production of fry of other species. The reported data from hatchery owners in response to inducing agent, fertilization rate, the hatching rate and survival rate of P. sarana were approximately 75, 67, 58 and 62%, respectively which was satisfactory indication for mass production of the species. The results suggested that the haor region of Sunamganj and Kishorganj district are the main resource of existing brood stocks. Necessary attempt should be taken for mass production of the species as well as conservation of its gene pool in Bangladesh.
