“…Considering these aspects extensive studies have been carried out in India on the microalgae occurring as phytoplankton. These include seasonal distribution (2)(3)(4), diversity of fresh water algae (4,(5)(6)(7)(8)(9)(10)(11)(12)(13)(14) physico-chemical parameters of aquatic system (3,4,(15)(16)(17) and algal blooms (4,18). These works have been carried out with respect to both lotic and lentic ecosystems.…”

A study on diversity, seasonal occurrence, distribution percentage of microalgal taxa and physico-chemical parameters of five community ponds, located in Chinsurah town, Hooghly district of West Bengal, has been carried out. Correlation between occurrence of microalgal genera and some parameters of environment, physico-chemical nature of natural water bodies were explored by Canonical Correspondence Analysis (CCA). Diversity indices have been calculated using PAST software program. A total of 23 microalgal taxa belonging to four algal classes were recorded and the study indicated that the microalgal diversity vary with variation in physico-chemical parameters of water and light intensity. Out of these genera, occurrence of Chodatella sp. in late summer and Tetrallantos sp. and Synechocystis sp. in winter season were specific. In CCA, multiple variables (dissolved oxygen, water temperature, electrical conductivity, pH, light intensity and inorganic phosphorous) played a significant role in occurrence of microalgal taxa. Observation concluded that the Chlorophycean members were dominant throughout the study period and the Shannon–Wiener diversity index was highest for a site with large number of Chlorophycean member. This study will help in future to assess water quality.

“…Many species of algae are involved in algal blooms and these species change over time based on temperature, light, nutrients, and other factors [2]. According to [3] attached algae may also live as epiphytes on other living organisms including larger attached algae, large planktonic colonial algae and higher plants. Fresh algae, frozen or heat killed algae, algae powder and baker's yeast are some of the food sources that have been exploited for the culture of rotifers [4].…”

In the current research work algal collection was made at different sites of River Naguman near its joining point with Sardaryab. Various sites expected to have rich algal flora across an area of 10 Km 2 were selected to obtain algal samples. A total of 38 species belonging to 16 genera of freshwater algae were collected and identified. Keys were constructed both at generic and specific levels for identifications and description. Out of these 16 genera Chlorophyta contributed 50%, Bacillariophyta 25%, Charophyta 6.25%, Xanthophyta 12.5% and Cyanophyta contributed 6.25% genera. Chlorophyceae were the most common represented by 60.53% species, Bacillariophyceae were next with 18.42% species, Charophyceae by 5.26%, Xanthophyceae by 5.26% and Cyanophyceae were represented by 10.53% species. The most dominant genus in terms of species was Spirogyra with eight species 21.1%. Cladophora and Oscillatoria were next dominants with 10.5% species. Rhizoclonium, Zygnema and Nitzschia were each represented by 7.9%. Closterium, Diatoma and Chara each contributed 5.3% species. All the remaining genera including Ulothrix, Mougeotia, Desmidium, Cyclotella, Tabellaria, Ophiocytium and Vaucheria each contributed 2.6% species.

“…Fresh water ecosystems are differentiated into various types of planktons (free floating), benthoms (attached to sediments) and epiphytic algae attached to hydrophytes, stones, mud, sand, reservoir rocks and lakes [3,4]. Various studies have been carried out in the Indian context related various aspects of phytoplankton such as seasonal distribution [5,6], diversity of fresh water algae [1,7,8,9,10,11,12,13,14,15], seasonal variations and physical-chemical aspects [6,16,17,18] and algal blooms [19].…”

ABSTRACT:The present study was conducted in a semi arid region of Karnataka. The study discusses the phytoplankton diversity of the Gogi lake ecosystem. A standard methodology was followed in conducting to complete this study and samples were collected at different points from the lake ecosystem located at the core area of the proposed uranium mining site. Through a field survey, twenty one species of phytoplankton were recorded coming under four classes viz.,
