Abstract

Budha Talab is the largest pond (30.25 ha.) among total 22 ponds present in the Raipur city. It receives domestic waste and sewage and also used for cloth washing, animal bathing and therefore water quality is fast deteriorating. Total 24 phytoplankton and 10 zooplankton species were identified. Among phytoplankton Scenedesmus sp., Microcystis sp., Oscillatoria sp., Anabaena sp., Melosira sp., Nitzchia sp., Chlorella sp. and among zooplankton Daphnia sp., Moina sp., Diaphanosoma sp. were found throughout the year. Microcystis sp., Oscillatoria sp., Melosira sp., Anabaena sp. (phytoplankton) and Brachionus sp. and Keratella sp. (zooplankton) indicate organic pollution and eutrophic nature of Budha Talab.

Abstract

Kumhari reservoir is one of the average productive small reservoir in Chhattisgarh. It is located near village Tilda and 22 kms from the block Kharora, in Raipur district. The small reservoir, Kumhari is situated between 21° 24' - 21° 96' N latitude and 81° 36' - 81° 52' E longitude. Agricultural lands surround this reservoir. The full surface level (FSL) is 986.58 ha and the Dead storage level (DSL) is 92.07 ha with an average water spread area, 539.23 ha. The depth is 12 m. However, as it has good water storage capacity, the reservoir is also used for stocking of cultivable fishes. Several native fishes also thrive in this reservoir along with stocked composite carp. The diversity of fish may be grouped in two categories like stocked Indian Major Carps and other native fishes. The fishes represent families like Cyprinidae, Channidae, Cichlidae, Siluridae, Percidae, Gobiidae, etc. The detailed taxonomic account of these fishes is documented in this paper.

Abstract

126 samples of C. catla, 129 samples of C. mrigala and 163 samples of L. rohita were sampled in Kumhari reservoir, Raipur, Chhattisgarh, India to study the growth parameters of length-weight. Log transformed regression were used to test the allometric growth. It was observed that the growth in weight is almost proportional to the cube of its length in L. rohita while C. catla and C. mrigala were slightly deviated from the cube of its length. The values of slope b = 2.8018, 3.4576 and 2.6275 were calculated for C. catla, L. rohita and C. mrigala respectively.
