STUDY ON ICHTHYOFAUNAL DIVERSITY IN RELATION TO PHYSICO-CHEMICAL PARAMETERS OF MANAKONDUR FRESH WATER LAKE OF KARIMNAGAR DISTRICT, TELANGANA STATE, INDIA

Freshwater bodies are one of the most common and stable habitats of biosphere. The freshwater habitats have their own physico-chemical and biological characters which are subjected to modify by local conditions and physiographic features. The water quality parameters have a great influence on the growth and other factors of aquatic organisms. Therefore, the lentic water body gives a good source for fisheries. The present investigation deals with limnological and physico-chemical parameters and their influence on Ichthyofauna abundance in Manakondur fresh water Lake at Karimnagar District, Telangana State. The study was carried out for a period of one year i.e., from June, 2020 to May, 2021.The investigation was focused on the determination of hydro-chemical parameters such as Water temperature(19.0-31.0ÂºC),Transparency(18.50-44.30cm),TDS(200-350mg/l),PH(7.5-8.3),DO(5.2-12.0mg/l),Co2 (3.0-9.2mg/l),TH(110-210mg/l),TA(165-300mg/l),CL(35.00-50.20mg/l),Po4 (0.02-0.16mg/l),No3 (0.02-0.14mg/l) and BOD(2.5-7.0mg/l).The study was made to recorded fish fauna available. Total 33 species of fishes were collected and identified during the study period which belongs to 6 orders, 12 families and 18 genera. The order Cypriniformes was dominant with 15 species, followed by Siluriformes (8 species), Osteoglosiformes(2 species), Perciformes(4 species), Channiformes(3 species), Perciformes(4 species) and Antherniformes(1 species) were identified. Order wise percentage composition is Cypriniformes (17%), Siluroformes (34%), (Osteoglossiformes(8%), Perciformes (25%), Channiformes (8%), Anthrniformes (8%) In the light of recent literature, the data has been discussed and it is concluded that limnological and physico-chemical parameters in this reservoir are most comply with suitability of human consumption and favourable for fishery.

Fresh Water Lake

<p>Chilika a shallow brackish lagoon, India, is shrinking for sediment surplus budget. South Mahanadi deltaic branches <em>i.e.</em> Daya and Bhargavi terminate at the southwest swamps of the Lagoon. The annual average salinity of the lake was depleted from 22.31ppt (1957-58) to 8.5 ppt. (1999-2000) as the mixing process of saline and fresh water was influenced from 1995. Trepidation of conversion of Chilika to a atrophied fresh water lake due to blooming population and their hydrologic interventions like Kolleru lake in (India), Aral Lake (Uzbekistan) was apprehended by 1950’s and was alarming by 1999 when the shallow inlet(s) shifted extreme north. The shallow mud flats of lean salinity were reclaimed further for agriculture. The ecology and biodiversity degraded with substantial pecuniary loss to the lagoon dependents. Anthropogenic interventions like, Hirakud dam (1956), dredging of Sipakuda Inlet (2000), Naraj barrage at delta head (2004), Gobardhanpur barrages (1998) and Gabkund cut with weir (2014) were made to the hydraulic system. The deteriorating health, perturbed biodiversity and declined ecosystem of the lagoon has forced to have a comparative study of the various morphologic changes passed over the Chilika with time. The meteorological, hydrologic and the salinity study of the lagoon area for the period 1990 to 2016 have shown changes. Topographic study using GIS is developed by collecting data from Glovis Classic (Google) and the interpretation is done using ERDAS 9.2 software for various geomorphic features (1984 and 2017) before and after the current anthropogenic interventions and compared with previous studies.</p>

Quality Status

In this paper, a study on the development of water quality index of ex-mining ponds was carried out for proper assessment and utilization of the abundant ex-mining ponds in Malaysia. Heavy metals were analyzed using inductively coupled plasma mass spectrophotometer (ICPMS), and physico chemical parameters were analyzed in-situ. Chemometric analysis was successfully applied for the parameter selection process. The water quality index of existing Malaysian river did not accommodate the toxic metal pollutants that dominanted in ex-mining water. The acceptable index should therefore incorporate the metal pollutants in order to evaluate the quality status of ex-mining water for human consumption which is the major point of consideration. Two water quality indices were developed to assess the water quality status of ex-mining ponds with reference to Malaysia’s water quality standard (INWQS). The heavy metal index was comprised of contribution from Pb, As, and Cd as the selected metals, while the physico-chemical parameter index has BOD, pH, DO, and AN. Chemometric analysis revealed the dominance of the selected heavy metals in ex-mining water, and physico-chemical parameters were important in water quality monitoring. Heavy metal water quality index revealed that most ex-mining ponds in Klang Valley were classified to be very poor hence could not be used for human consumption. Due to domestic input in some of the lakes in Klang Valley, the physico-chemical water quality index was in very poor status as well. In Melaka and Negeri Sembilan, ex-mining ponds and lakes were classified as excellent in both indices.
