“…The pH value for all the PWs except PW 13 ranged from neutral to slightly alkaline, which lies within the values preferred by the WHO (6.5-8.5) [31]. Neutral to alkaline pH was found to be very suitable for the growth of cyanobacteria [30].…”

Cyanobacteria notably called blue-green algae mostly inhabit moist soils and water. These species constitute a major part of the phytoplanktonic biomass in freshwater ponds. cyanobacteria serve as the significant resource in various applications like medicine, mariculture, feed, fuel, and in combating pollution. Cyanobacterial biodiversity provides various useful insights and is considered an important ecological parameter in freshwater aquaculture. The present research work aims to study the biodiversity of cyanobacteria among 20 different freshwater ponds in Pudukkottai district, Tamil Nadu, India. The samples were collected and pure culture was obtained, followed by maintenance in the BG-11 medium. The species were identified and classified based on the size, shape, and color (morphological features) of the blue-green algae using a trinocular microscope. The physicochemical characteristics such as pH, temperature, biological oxygen demand, chemical oxygen demand, etc., of the freshwater ponds were also studied as they greatly influence the cyanobacterial biodiversity. The abundance of cyanobacteria was seen in a low amount of dissolved oxygen, pH of 8.0 with high oxidizable organic content. About 42 distinct cyanobacterial species were isolated consisting of 25 versatile families of cyanobacteria. Chlorophyceae was found to be predominantly present in the fresh water ecosystem, followed by Cyanophyceae, Bacillariophyceae, Ulvophyceae, and Dinophyceae. The present study revealed the biodiversity of blue-green algae from the fresh water ponds of Pudukkottai District which holds as the baseline data for the more detailed studies in future.

“…The parameters that influence the growth of cyanobacteria in the fresh water ponds include oxidizable matter, nitrogenous content, light intensity, and dissolved oxygen [25][26][27][28][29][30]. Also, the water level fluctuations might lead to an increase or decrease in the cyanobacterial species diversity.…”

“…Wetlands near rivers, for example, control phytoplankton productivity, which is the foundation of the trophic chain and indicates water quality. These are typically influenced by nitrogen and phosphorus concentrations (Narchonai et al, 2019). Water quality monitoring is carried out by several environmental institutes (Adloff et al, 2018).…”

Limnology is the study of the aquatic system. The current research focuses on the physical, chemical, and biological properties of Bomani beel and Garjan beel in the Kampur district. The study looked into the existence of phytoplankton and compared it to two different beels. The community of plankton changes the water quality based on the parameters. The study looked at 12 water quality characteristics, as well as algae weight analysis and statistical analysis. There are no significant differences in temperature, pH, alkalinity, hardness, turbidity, or other chemical properties. The chlorophyll-a varies significantly; for example, in the winter, the Bomani beel has 10.232 and the Garjan beel has 7.312. Both beels have a Mesotrophic trophic state index. As a result, it is critical to raise public awareness and develop policy strategies for the conservation of these natural resources.

“…However, presently the importance of temple tanks is waning, and many of the temple ponds are been neglected, disused, or used as a garbage dump, and in some cases, children use the dry temple ponds as playgrounds. A brief survey of literature on phycological studies of this region revealed that only a single report is available on the microalgal diversity of two temple ponds in Puducherry [ 18 ]. The present study is an attempt to examine, record algal variety, and analyse the physicochemical composition of the pond water.…”
