Abstract:
The Rajnandgaon reservoir, located in the Rajnandgaon district of Chhattisgarh, India, is a significant water body that supports a rich diversity of fish fauna. Several studies have been conducted to assess the fish diversity in this reservoir, revealing a variety of species belonging to different orders and families. The studies indicate that the Cypriniformes order, particularly the Cyprinidae family, is the most dominant group in the reservoir. This family includes various carp species, such as Labeo rohita, Catla catla, and others. These species are not only important for the ecosystem but also hold significant commercial value. Siluridae family comprises catfish species, which are also common in the reservoir. The Channidae family includes snakehead fish, known for their predatory nature. Cichlidae family includes cichlids, which are often brightly colored and popular in aquariums. The reservoir's varied habitats, such as open water, shoreline areas, and submerged vegetation, provide suitable niches for different fish species. The water quality parameters, such as temperature, oxygen levels, and nutrient availability, play a crucial role in determining the survival and distribution of fish species. Fishing pressure, introduction of exotic species, and pollution can impact the fish diversity in the reservoir.
