The present study deals with phytoplankton population of Navule pond in Shivamogga during September 2014 to August 2015. Blue-greens constituted the major group (41.75%) followed by Chlorococcalas (36.68%), Diatoms (13.36%), euglenoids (7.35%) and Desmids (0.86%). The phytoplankton community was composed of 11 species of Blue-greens, 20 species of Chlorococcales, 18 species of Diatoms, 11 species of Euglenoids and 08 species of Desmids. Each group of phytoplankton showed different peak periods, the summer season produces relatively more phytoplankton than rainy and winter season. The variations in physico-chemical parameters are responsible for the fluctuation of quantity of phytoplankton.  The dominant genera recorded on the pond were Anabaenopsis sp., Ocillatoria sp., Euglena sp., and Phacus. Some of the pollution tolerant species identified during the present study are Scenedesmusquadricauda, Coelastrum sp., Tetraedonmuticum, Ocillatoria sp., Phormidium sp., Microcystis sp., Anabaena sp., Navicula sp., Synedra ulna, Cyclotella sp., and Pinnularia sp. In the present study Microcystisaeroginosa was recorded indicates the civic pollution.

Abstract: Different Physico-chemical parameters of Kanekal tank water, Kanekal were estimated from October 2012 to September 2014 to assess its quality. The different parameters like Temperature, pH, TDS, conductivity, salinity, dissolved oxygen, turbidity, alkalinity, free carbon dioxide, chloride, total hardness, calcium, magnesium, phosphates, sulphates, silicates, nitrites, nitrates, BOD and COD were carried out by standard methods. These parameters showed either positive or negative correlation between each other. The analysis revels these parameters are interrelated with each other. From the data it can be said that water of this tank is partially contaminated with human faeces, domestic sewage etc. Hence it is not good quality for culture of fish as well as drinking for animals.Keywords –Kanekal Tank, water quality, Physico-chemical parameters, BOD, COD

A twelve-month study was conducted to examine the influence of physico-chemical parameters on the primary production of Nworie River to assess its suitability for fish culture. Water samples were collected from three stations along the river course and examined for various parameters. Data collected were analyzed using multivariate analysis, stepwise linear regression and spearman correlation while Tukey’s honestly significant difference was used to separate the means. Results showed that water temperature was significantly different (p<0.05) at all stations and were within normal range for fish culture. Similar observation was made in, the levels of conductivity, total dissolved solids (TDS), nitrogen-nitrate, free carbon dioxide, depth, chlorine, hardness and primary productivity. The levels of dissolved oxygen (DO) and phosphate-phosphorus were not significant (p>0.05) but within normal range for fish culture. Alkalinity and pH showed significant differences (p<0.05) in all stations during the study. In Station 1, alkalinity and pH levels were 8.06±1.9mg/l and 5.4±0.3mg/l respectively. Heavy metal concentrations recorded revealed that the levels of Chromium (Cr), Cadmium (Cd), and Zinc (Zn) were significantly different (p<0.05) in all stations and were within permissible limit for fish culture while the level of lead (6.72±0.78 – 7.540.36mg/l) was not. The regression analysis revealed that variables in DO, TDS, free CO2, Cd, and depth influenced primary productivity and were both positively and negatively correlated at 5% and 1% probability levels respectively. The authors thus concluded that Nworie River may not support aquaculture development until some ecological situations are remedied.

The aim of the study was to assess the effect of temperature on the occurrence of desmids on a lentic waterbody viz. Jawahar Bal Udhyan Pond situated in northern direction of the Bhopal district with reference to its seasonal variation in physico-chemical parameters. Water temperature of the lentic water body varied between 16.2°C to 31.9°C in winter and summer season respectively. During the present study period a total of 18 desmid taxa of 6 genera were encountered in which Cosmarium dominated in terms of species diversity. Desmids occurred maximum in winter season i.e., from December to February and minimum in post monsoon season i.e., from October and November. Different species of Closterium, Euastrum, Staurastrum, Pleurotaenium, and Sphaerozosma are considered as pollution tolerant species and the presence of all these species and result of physico-chemical parameters indicates the meso-eutrophic condition of the waterbody.

This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.

The Relationship

Diurnal vertical migration of four genera of cladocerans, namely Diaphanosoma sp., Daphnia sp., Moina sp. and Bosmina sp., during March to December, 2007 showed that the number of Diaphanosoma sp. was 501 units/1 in the surface layers, 172 units/l in the middle layers and 190 units/l in the bottom layers. The yearly number of Daphnia sp. in surface, middle and bottom layerss was 362 units/l, 46 units/l and 189 units/l respectively. In surface, bottom and middle layers, the number of Moina sp. was 159, 71 and 32 units/l, respectively. Bosmina sp. was 78 units/l in surface, 31 units/l in the middle and 33 units/l in the bottom layers. The number of Diaphanosoma sp., Daphnia sp., Moina sp., Bosmina sp., were 455, 149, 259 and 358 units/l, respectively in the morning, 63, 176, 142, 43 units/l at noon and 107, 55, 28, 59 units/l, respectively in the evening. Throughout the study period the cladocerans were always abundant near the surface during morning and evening. Among the factors responsible for the diurnal movement of cadoceran, light played the most important factor. The relationship between the physico-chemical factors and the cladoceran occurrence in the pond was also explored.
