random amplified polymorphic DNA (RAPD) variations were carried out. Five primers produced 102 scorable bands 38 (37.25%)
were polymorphic and 64 (62.74%) were monomorphic. The percentage of polymorphic loci was higher in pond (41.18%) than
that of Cages (35.29%) and river Narmada (32.35%).The gene diversity and Shannon’s Information Index values of the pond
(0.16, 0.24) was higher followed by Cages (0.15, 0.22) at Kerwa Dam and then from Narmada (0.12, 0.18).The observed number
of alleles was higher in pond (1.41) than in Cages (1.35) and Narmada (1.32) however, the effective number of allele were more
or less similar in all the three populations. Genetic Identity observed between Pond and Narmada is 0.9235(92.35%) whereas
between Cages and river Narmada is 0.9602(96.02%) and between Cages and Pond was 0.9592 (95.92%). The dendrogram
separated the accessions collected from three different locations into two major groups based on the Genetic Diversity (GD). No
significant difference was observed between the genetic distances of T.tor populations from the three sampling sites. The
genetic difference of accessions of T. tor from three populations might be due to the result of abiotic and biotic factors. It can be
predicated that every finite populations may not experience genetic drift, but the effect will become more pronounced as
population size and geographical distribution increases and in due course there might be low genetic variation.

in fisheries and livelihood security of the local community. With the increase in population growth reservoirs are
becoming important provider of animal protein and for generation of employment in particular to poorer sectors of the
people. Reservoirs have many uses from generation of electricity to irrigation purpose and also providing habitat to
fishes and other aquatic life and in turn also help to provide feed and create revenue for fish communities. In India,
reservoirs are playing a crucial role in the fisheries. Fish communities are often used as indicators of environmental
quality. In terms of fish diversity altogether 117 fish species were recorded from Indian reservoirs exhibiting rich
fish diversity. These reservoirs have both positive and negative impacts on fishes and other aquatic environment.
Therefore, present study is emphasized on synthesizing the available information on fish diversity and community
structure of the potential Indian reservoirs and its effects on fisheries and other aquatic environment in reservoirs in
India. Some strategies have been suggested for sustaining river and reservoir fish biodiversity.

'Fish Karyome' database was the preliminary attempt to compile and digitize the available karyological information on finfishes belonging to the Indian subcontinent. But the database had limitations since it covered data only on Indian finfishes with limited search options. Perceiving the feedbacks from the users and its utility in fish cytogenetic studies, the Fish Karyome database was upgraded by applying Linux, Apache, MySQL and PHP (pre hypertext processor) (LAMP) technologies. In the present version, the scope of the system was increased by compiling and curating the available chromosomal information over the globe on fishes and other aquatic organisms, such as echinoderms, molluscs and arthropods, especially of aquaculture importance. Thus, Fish Karyome version 2.1 presently covers 866 chromosomal records for 726 species supported with 253 published articles and the information is being updated regularly. The database provides information on chromosome number and morphology, sex chromosomes, chromosome banding, molecular cytogenetic markers, etc. supported by fish and karyotype images through interactive tools. It also enables the users to browse and view chromosomal information based on habitat, family, conservation status and chromosome number. The system also displays chromosome number in model organisms, protocol for chromosome preparation and allied techniques and glossary of cytogenetic terms. A data submission facility has also been provided through data submission panel. The database can serve as a unique and useful resource for cytogenetic characterization, sex determination, chromosomal mapping, cytotaxonomy, karyo-evolution and systematics of fishes.

rivers flow in state but river Narmada originating from Amarkantak Hill (Madhya Pradesh) is referred
as “Life line of Madhya Pradesh”. This river is the natural abode of wide variety of fish diversity. Tor
tor (the deep-bodied mahseer), locally known as “Badas” is one of the largest freshwater cyprinid
and a native of river Narmada. This fish is famous for its fighting character during angling and because
of its exclusive good taste, it is ranked on the top of all commercial catches of river Narmada. T. tor
is a potential candidate for the development of open water fishery as well as aquaculture. Recently,
due to wide-spread anthropogenic activities, the natural population of T. tor is getting depleted
rapidly in river Narmada and has been declared as Near-Threatened (IUCN, 2015). Hence, there is an
urgent need for further research and species diversity study for conservation of mahseer. This study
reviews information on mahseer species with special emphasis on T. tor of river Narmada. Disciplines
that are covered in this study ranges from the taxonomy and systematic to its biological, reproductive
and conservation aspects. More studies are suggested on different aspects of domestication,
propagation u

Plankton abundance in culture pond depend on the factors such as ambient nutrient concentration, the physical state of the water. Mahseer (T.tor) known as the state fish of Madhya
Pradesh is one of the most important game and food fish that have an endangered status so its conservation is very important for its feeder protection. It is
an omnivorous feeder. By liming and fertilizing with manures and fertilizers the production of plankton is undertaken which are the fish food organisms. On monthly sampling 15 species of phytoplankton, of which chlorophyceae are recorded as the highest. They are followed by zooplankton in which Rotifers
are recorded as the dominant group. The gut analysis revealed the existence of highest range of zooplankton followed by phytoplankton. The importance of natural food is reflected properly in its relative contribution to the gut content.
