...nvironmental factors and phytoplankton biomass are investigated in Lake Nansihu. A total of 76 zooplankton species were identified in the lake, including 17 protozoa, 36 rotifera, 12 cladocera and 11 copepods species, respectively. Zooplankton species richness changed slightly in the four seasons but varied a lot in different positions. Protozoa was absolutely dominated in zooplankton abundance and its mean value ranged from 2710.2 ind./L in winter to 4259.5 i...

The high salinity zone in the estuary downstream was dominated by the calanoid paracalanidae and the harpacticoid Euterpina acutifrons. In the lower salinity transects, the tintinnid Favella serrata dominated the estuary midstream, together with several rotifer species in the estuary upstream. The juvenile copepods and the c...

Ponds water sample (50 liters) was filtered through plankton net of 20 µm pore size and preserved in 4% formaldehyde for the analysis of phytoplankton. Subsequently, the phytoplankton were counted un...

Our research showed that the cultured ponds had high abundance of phytoplankton but low species diversity. Meanwhile, the water inlet and outlet of the shrimp farming which served at mangrove area had higher phytoplankton diversity. The composition of

Water samples were collected monthly (Jan-Dec, 2019) from different sites of the ponds and studied the total abundance of plankton in each month. During the study, physicochemical parameters of the pond water like temperature, pH, dissolved oxygen, salinity, transparency, ammonia, phosphates, nitrates, potassium, calcium, total alkalinity...

In total, 37 fish species were found in the study area, with species richness rising from zone one (n =10) to zone five (n =33). Altogether, the fish diversity represents 25 genera and 13 families. To analyze the data, principal component analysis (PCA) was done by using XLSTAT and excel 2019 to study the factors affecting the water quality. The eigenvalues obtained afte...

For the qualitative and computable examination of planktons, the 50 liters of bay water was strained and residue fixed with 5% formalin in sampling bottles. The 99 genera of both the planktons were recorded, which included 52 zoo- and 47 for phytoplankton from the experimental area. Among the zooplankton, Copepods were found to be ric...

Collected Species were scrutinized taxonomically by using light microscope. In all studied sites genus Scenedesmus was dominant with fifteen species in both seasons, while all other micro-algal species were dominant at site E1, Salarzai Thali Dam in March spring session. ...

EPSs produced by bacteria include a broad range of chemical structures and may either be heteropolymeric or homopolymeric. Their molecular weights vary from 10 to 1000 kDa. Exopolysaccharides have multifarious applications in different fields of life. These EPSs are used as anticoagulant, immunomodulator, emulsifiers, anticancer and bioflocculants. They are wid...
