Physico-chemical property of water, zooplanktons and Diversity of plankton Plankton refers to plants and animals that drift with the ocean currents and fresh river water .they habitants in the open waters of the sea and fresh river water. Zooplankton (from Greek zoon, or animal) are Small protozoans or metazoans (e.g. crustaceans and other animals) that feed on other plankton and telonemia. Some of the eggs and larvae of larger animals, such as fish, crustaceans and annelids, are included in Zooplankton. Physico-chemical parameters are very important factors that play a significant role in river zooplankton diversity and fluctuation. We evaluated impact of Abiotic factor on plankton diversity during pre, middle and post winter analysis of Singoda River Copy Right, IJAR, 2017,. All rights reserved.Plankton is organisms which live suspended in the water of seas, lakes, ponds, and rivers, and they are not able to swim against the currents of water. This latter feature distinguishes plankton from nekton, community of actively swimming organisms like fish, larger cephalopods and aquatic mammals. Plankton form complex biotic communities which are functionally as diverse and show the same richness of interaction as terrestrial communities. Plankton is defined by their ecological niche rather than their phylogenetic or taxonomic classification. They provide a crucial source of food to larger, more familiar aquatic organisms such as fish. The zooplankton is divided into two groups. Temporary plankton consists of planktonic eggs and larvae of members of the benthos and nekton, permanent plankton includes all animals that live their complete life cycles in a floating state and the temporary plankton particularly abundant in coastal areas, it is characteristically seasonal in occurrence, though variations in spawning time of different species ensure its presence in all seasons. They are absent in fresh water. The ciliate protozoans are represented mainly by the tintinnids, which are between 20 and 640 microns in size and sometimes occur in vast numbers. Oysters, mussels, other marine bivalves and snails begin life as planktonic larvae. The wing snails (Pteropoda) spend their entire life cycles as plankton. Crustaceans are the most important members of the zooplankton. They are the marine counterparts of insects on land as in the sea, the arthropods are the most diverse and numerous of all animal phyla. The copepod Calaanuslinmarchicus is important as food for the herring, and the euphausiid Euphausia superba, commonly known

Journal of entomology and zoology studies, 2017
The present study on river Sutlej deals with the seasonal variations in the diversity of phytoplankton and zooplankton population at two different sites of the river (one is River Sutlej before the confluence of the Buddha nallah (S-1) and second is River Sutlej after the confluence of the Buddha nallah (S-2)). Studies revealed that phytoplankton population was dominated by members of Bacillariophyceae, Chlorophycea, Cyanophycea and Euglenophycea and Zooplanktons population was dominated by Protozoan, Rotifer and Crustacea. Relative abundance of Bacillariophycea and Euglenophycea was higher at S-2 as compared to S-1 whereas that of Chlorophycea and Cyanophycea was higher at S-1 as compared to S-2. Relative abundance of Crustacea and Protozoa was higher at S-2 as compared to S-1 whereas that of Rotifera was higher at S-1 as compared to S-2 during the monsoon period.
Zooplankton Diversity of Godavari River at Mudgal Dam, Pathari Dist. Parbhani (M.S.), India
International Journal of Biological Innovations, 2024
Aquatic ecosystem has a vast diversity of micro-eukaryotes (rotifers, crustaceans and protists), and such diverse taxonomic groups play important roles in ecosystem functioning and services. Farming organisms such as fish receive nutrients other than minerals by taking food. In nature, most organisms survive by consuming live food such as plankton from the environment. Zooplankton are of great importance and basically essential in fish culture. The present work is carried out for the assessment of plankton diversity of Godavari river water in Mudgal dam area for a period of one year starting from March, 2019 to February, 2020. The zooplankton serves as a food for other higher organisms. During the exploration, authors recorded four groups of zooplankton namely Rotifera with 7 species, Cladocera with 5 species, Copepoda 3 species and Ostracoda 2 species.

Sundarban Estuarine System is influenced by periodic tidal input and fresh water inflow. It is surrounded by world’s largest mangrove ecosystem and harbour naturally grown fishery. The total system is intersected by a network of many rivers and creeks. Bidyadhari is one of the major rivers of Sundarbans that is surrounded by human habitation on both banks. The dynamic condition of the river due to tidal inflow and fresh water input which is further increased many folds due to human interventions. In the present study, 26 zooplankton taxa have been recorded where 16 taxa were found perennial in all three seasons. 19 species showed its highest density in the monsoon season, 4 in post-monsoon and 3 in pre-monsoon season. Considering all seasons, Pseudodiaptomus serricaudatus was found to be the most abundant species in monsoon when there was a marked increase in temperature, nitrate, phosphate, silicate and a decrease in salinity, DO, TDS, EC and chlorophyll-a concentration. On the other hand, Acrocalanus longicornis was most abundant during the post-monsoon season when pH, EC, DO, chlorophyll-a were found to be highest and temperature was lowest of all seasons. Only 3 of the 26 taxa were found in highest concentration during pre-monsoon season when salinity was found in highest concentration. The Shannon-Weiner Diversity Index, Simpson 1_D Index and Margalef Richness Index of zooplankton diversity were found highest in station 3 (nearest to the sea) during all the three seasons. Pearson Correlation Analysis showed some significant correlation between different hydrological parameters and zooplankton diversity indices. The result of the study indicates the presence of organic pollutants and eutrophication in Bidyadhari river that demands regular monitoring of water quality for maintenance of long-term sustainability of one the largest naturally grown fisheries in the world.
ENVIRONMENTAL INTERACTIONS OF ZOOPLANKTON IN THE CHAMBAL RIVER AT NAGDA (M.P.INDIA
The present study was aimed to examine the intra and interrelationships of zooplankton biodiversity with their environmental factors at Chambal River (23° 4561′ N and Long 75° 4227′ E), Nagda (M.P.India). Zooplankton diversity studies in the upstream and downstream of the river were performed in December 2019. Surface waters from the same locations were collected and analyzed for eight physico-chemical parameters like temperature, pH, dissolved oxygen, transparency, phosphate, nitrate, sulphate and chloride following the standard methods of APHA (2012) to assess the level of pollution load in the reservoir. Results revealed that the values of water quality parameters of upstream were slightly exceeded the ideal values but found to well within the standards of BIS and ICMR. However, the values of all water quality parameters of downstream were found to be significantly higher and exceeded the maximum permissible limits of BIS and ICMR. The species composition at the Chambal River during the winter months of 2019 at two study stations includes a total of 1453 individuals. Out of 1453, Rotifera comes out as a top group with 579 (40%) individuals followed by Cladocera 35% (514), Copepoda 22% (324), and Ostracoda 3% (36). The species abundance was more in station 2 with 1020 individuals followed by Station 1, (433). Five biodiversity indices like the number of species, Dominance index (D), Simpson (1-D), Shannon-Wiener diversity index (H), evenness index were calculated by using PAST software (version 326b). The site-wise diversity indices showed significantly lower values in downstream than upstream. The Pearson correlation coefficient matrix analysis describes the positive correlations between various diversity indices like Dominance (D), Simpson (1-D), Shannon-Wiener (H) and evenness with water temperature, pH, DO, chlorides and phosphorus and shown negative correlations with nitrates and sulphate values. The outcome has been argued from the point of view of interactions of zooplankton with water quality parameters. The study confirms that downstream of the Chambal River at Nagda is highly polluted and not suitable for human consumption. The study advocates implementing strict laws and guidelines to protect the water quality status.
