"Ornamental fisheries, especially rearing and breeding of freshwater aquarium fish have gained popularity in India over the last two decades or so. North-Eastern India being one of the mega-diversity regions in South Asia, the aquarium fish traders obviously identified the region, especially the floodplains of the Brahmaputra River as a hunting ground for exploitation of endemic and colourful fish species and their export to the far eastern countries. But what is surprising that we do not have a proper documentation or baseline information about the exact number of species currently available in the Brahmaputra Basin and their ornamental features, rating and compatibility. After all, one requires comprehensive biological informations of the fish and their habitats in order to rearing, feeding and breeds them in captive condition. This handbook on ornamental fishes of the Brahmaputra basin will serve as a baseline data not only for the naturalist but also for the aquarist who would like to venture the world of ornamental fishes.".

Apart from dealing the basic fish behaviour and ecological relations, population studies, genetics and hybridization etc. Where-ever necessary, references are cited for authentication of the subject matter. For the benefit of our students more emphasis has been given on tropical freshwater species. Inclusion of over 400 technical terms should be an added attraction of the book."No. 24598 392 pp.

Hardcover. Condizione: New. Although in the global context, emphasis of research is given more on molecular biology and biotechnology; the importance of basic research cannot be overestimated. This is more so in the case of India's northeast region. The region is ell known for its rich biodiversity and a good number of research papers in plant and animal sciences were published in the last few decades. However, it is also a fact that documentation of bioresources of the region is far from complete. Little is known about the distribution and current status of many of the endemic and rare species of the region. It is also necessary to have a scientific information on the traditional usage and active ingredients available in the edible/medicinal plants, animals and microbes, and also how to maintain habitat ecology and formulation of strategies for sustainable utilization of bioresources of the region. The book given an overview of the present trend of research in biological sciences in the north-east India.
