ICHTHYOFAUNA OF WASHIM DISTRICT MAHARASHTRA
The ichthyofauna of reservoirs of Washim district basically represents the fish faunal diversity. Indian reservoir preserve a rich variety of fish species, on the basis of studies conducted so far, large reservoirs on an average herbivore 60 species of fishes, of which 40 species contribute to the commercial fisheries. Indian major carps occupy a prominent place among the commercially important fishes. More recently, number of exotic species has contributed substantially to commercial fisheries. Being basically a carp country both the indigenous and exotic carps, catla, rohu, mrigal, silver carp, grass carp and common carp, account for a great bulk of the production. Catfishes dominate in some of reservoirs in India. During recent years there has been increasingly greater concern for inland fresh water resources, which are affected in different ways by all kinds of human activities. The man made lakes are but one such example of water resources, which form a part of a still larger system, the watersheds. Any human activity in the whole of the watershed is bound to influence the water in the reservoir and downstream. Deforestation, grazing and otherwise removal of vegetal in the watershed generally results in accelerated silting of the reservoir. The agricultural practices in the catchments area not only help increased silting but also responsible for addition of large quantities of nutrients, pesticides and organic matter, brought to the reservoir by the runoff through the stream. Not only the water quality in the reservoir is affected but its impact can also be left in the change in the biota, soil properties and physico-chemical status.
