Description :
India is one of the mega biodiversity country in the world and occupies the 9th position in terms of freshwater mega biodiversity. Fishes are rich source of food and nutrition. In India, there are 2,500 species of fishes, of which 930 live in freshwater and remaining 1,570 are marine. The Dongar Haldi (Mal) lake is situated in Dongar Haldi (Mal) village in Pombhurna Tahsil of Chandrapur District of Maharashtra. This lake is surrounded by natural forest and hilly terrain. It is 39 Km from Chandrapur. The aquatic weeds of the lake were classified into five different types as free floating, submerged floating, rooted submerged, marginal and emergent weeds. Aquatic weeds are present in places of marshy land and water logged areas throughout the world. The weeds are disturbing to the production of aquatic weeds, is of primary importance for their control and management. Species of macrophytes are of great importance today as far as natural food supply to fish species is concerned. These weeds provide the nutrients and foods to fishes and some weeds are the harmful for the fishes. In this lake, total 5 species of fishes were found at the time of fishing, viz., Catla, Rohu, Mrigal, Cyprinus and Giant Freshwater prawn Macrobrachium rosenbergii. Total collection of fishes and prawns is 10 to 15 tons per year. The Dongar Haldi (Mal) lake is suitable for the aquaculture practices. From the present study, it may be concluded that - The Dongar Haldi (Mal) lake exhibit a good fish diversity represented by 5 species of fishes and prawn species. In this lake, aquatic weeds are present in large quantity. They restrict fish movement and interfere with fishing operations.
