In the present study efforts have been made to ascertain the seasonal abundance and population dynamics of zooplankton community and its relationship with physico-chemical factors of the water bodies of Santragachi Jheel in the District Howrah, W.B., INDIA. The zooplankton abundance showed distinct seasonal or temporal variation in the Jheels. A total of 18 species belonging to 12 families and 15 genera were recorded. The population density of total zooplankton showed summer maxima in the Jheel. Maximum abundance of rotifer fauna was recorded during summer season in sewage sites whereas Cladocera population showed maximum density at non-sewage sites. Copepods showed postmonsoon maxima in sewage sites in the Jheels. Some species i.e., Polyarthara vulgaris were quite abundant in the polluted water of the Santragachi Jheel. Out of 15 genera of Zooplankton, Brachionus, Keratella, Polyarthra, Diaphanosoma, Ceriodaphnia, Bosmina, Heliodiaptomus and Mesocyclops were found to be dominant in Santragachi Jheel. Highest percentage of similarity was recorded between S1 and S3 sites of the Jheel. Results of ANOVA (2 - way) indicated that zooplankton population differs significantly in relation to stations and seasons of the Jheel. Population of Rotifera, the most dominant group was found to be positively influenced by Biological Oxygen demand (BOD), Free Carbon-di-oxide FCO2), CaCO3 hardness (CaHa), Total suspended solid (TSS), Chloride(Cl) and Phosphate (PO4) in the Jheels. Total Cladocera showed positive correlation with PO4 in the Jheel. The Copepods expressed positive correlation with BOD and ammonia. Increment of population density of several zooplankton organisms (i.e., Keratella tropica, Polyarthra vulgaris) and low value of community indices especially species diversity and species richness indicated the rise of pollutional stress on the Santragachi Jheel.

Halda is an important river of Bangladesh, is now polluted in different ways through industrial, agricultural, domestic and sewage disposal. Increased anthropogenic activities have increased the potential pollution of the river and excessive pollutants may be toxic to humans and aquatic fauna. Presence of heavy metals in the river water causes perilous impact on the aquatic organisms. Hence, regular monitoring of pollution levels in the river is indispensable. In this study, we discuss about physico-chemical assessments of water quality parameters viz. pH, dissolve oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total solid (TS), total suspended solid (TSS), total dissolved substance (TDS), total alkalinity, turbidity, salinity, electrical conductivity (EC), hardness, chloride and heavy metals in the water of Halda river during rainy and winter seasons, at different points; sources of pollutants in water and their effects given starting from the early research until the current research.

AbstractThe community composition of zooplankton with an emphasis on copepods was assessed in the frontal zones of the Indian sector of the Southern Ocean (SO) during summer 2013. Copepods were the dominant group in both the bongo net and multiple plankton sampler across the entire region. High zooplankton abundance was recorded along each transect in the Polar Front (PF). Community structure in this front was dominated by common taxa, including Ctenocalanus citer, Clausocalanus spp., Calanoides acutus, Calanus propinquus, Calanus australis and Rhincalanus gigas, which together accounted for > 62% of the total abundance. Calocalanus spp., Neocalanus tonsus and C. propinquus were indicator species in the Sub-Tropical Front (STF), Sub-Antarctic Front and PF, respectively. A strong contrast in population structure and biovolume was observed between then PF and the STF. The community structure of smaller copepods was associated with the high-temperature region, whereas communities of larger copepods were associated with the low-temperature region. Thus, it seems probable that physical and biological characteristics of the SO frontal regions are controlling the abundance and distribution of zooplankton community structure by restricting some species to the warmer stratified zones and some species to the well-mixed zone.

The present study was carried out on the seasonal abundance and diversity of zooplankton in a semi- intensive shrimp farm of Bagerhat district from June to December, 2008. Plankton samples were collected by conical shaped monofilament nylon net (Plankton net) and Lugol’s solution was used for preservation. The zooplankton abundance was influenced by physico-chemical factors. In the present study 5 groups of zooplankton were observed namely rotifer, copepod, cladocera, ostracoda and crustacean larvae. Among the various groups of zooplankton, the percentages of copepod, rotifer, cladocera, ostracoda and crustacean larvae in the culture system were 52%, 39%, 7%, 1% and 1% respectively. The zooplankton was dominated by copepods (52%) which showed more or less two peaks in August (833 individuals/L) and in October (815 individuals/L). Rotifer and copepod were about r awhile one genus Cypris of ostracod was found only in August. Three genus of copepod namely Diaptomus,  Cyclops and Mesocyclops were identified in the study area of which Diaptomus and Mesocyclops were more or less dominant while four genus of which Brachionus and Filinia under rotifer and Daphnia and Diaphanosoma under cladocera were also found during the study period. The findings of the present study will help to improve the management strategies of shrimp culture system.DOI: http://dx.doi.org/10.3126/ijls.v5i1.5286 International Journal of Life Sciences Vol.5(1) 2011 1-11

Effluent discharged from the Karnali distillery Pvt. Ltd was analyzed to measure its effect on agricultural crops and environmental justice to the concerned people. Physico-chemical parameters like pH, temperature, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Particles (TSS), Nitrogen (N), Phosphorus (P), Potassium (K) and some heavy metals such as Iron (Fe), Manganese (Mn), Cadmium (Cd), Lead (Pb), Zinc (Zn), and Copper (Cu) were analyzed and found most of the physico-chemical parameters were above the toxic level set by Nepal Bureau Standard. The analysis of physico-chemical parameters of the soil irrigated with effluent polluted water revealed appreciable increase in the soil nutrients (Organic Matter, N, P, K) along with the increase of toxic heavy metals such as Fe, Cd, Mn and Pb in the soil which has decreased annual crop productivity by around 40 percent. Similarly the effect of the effluent on seed germination, seedling growth, fresh weight and dry weight of seedlings of two test crops (Oryza sativa and Triticum aestivum) were also analyzed and found the effect varied in different concentration of treatment. Higher concentrations (10%, 25%) were found completely inhibitory where as lower concentrations (1%, 5%) were found stimulatory and reached up to the level of control. The present study showed that the distillery effluent was highly loaded with organic pollutants along with harmful heavy metals which showed significant effect on soil quality and the crop productivity which caused environmental injustice to the local people in terms of loss of crop productivity and environmental hazards.

Abstract: This study focuses on assessment of zooplankton with special reference to seasonal variation and selected physicchemical variables of Kampli water tanks in Hosapete city, Karnataka state. A large quantity of manmade activities near the water tank. During the study period, 48 species of zooplankton - 14 species of Rotifera, 12 species of Cladocera, 6 species of Ostracoda and 4 species of Copepoda were observed. Among zooplankton, Rotifera was (645 no./Org) noticed as the dominant group in the entire the study period and the maximum count was identified in the summer period while less numbers were noticed during winter season. Zooplankton community is also significantly correlated with some physico-chemical variables. The analytical results during the study period indicate that the scattering and density of zooplankton species were encouraged by prevailing physical and chemical features of the aquatic ecological condition. Keywords: Kampli, water tank, zooplankton, diversity, seasonal and domestic activity.

Abstract Biological Oxygen Demand (BOD), Total Suspended Solid (TSS) and Dissolved Oxygen (DO) are indicators of water quality in water bodies. Non-polluted water has low BOD and TSS levels and high DO. Changes in these three parameters indicate a change in quality. This study aims to look at variations in the levels of BOD, TSS and DO spatially and temporarily in Batang Arau River, Padang City in 2018. The study was conducted by observing three stations, namely in the upstream, middle and downstream and in the morning and evening. The results showed that BOD and TSS levels tended to increase from upstream to downstream, while DO was the opposite. Temporar variation shows that BOD and TSS levels are low in the morning and increase during the day and evening, while DO is the opposite. Key word: Biological Oxygen Deman, Total Suspended Solid, Dissolved Oxygen Abstrak Kbutuhan Oksigen Biologis (BOD), Total Suspended Solid (TSS) dan Dissolved Oxygen (DO) adalah indikator kualitas air dalam badan air.

Few studies were made about zooplankton distribution in Jazan coastal area. The present study dealt with the identification of zooplankton at the sandy shore (AlSalwa coast) and mangrove muddy shore (Turfa peninsula) at the Almarjan coast. Species richness and population density at different seasons were determined for both study areas between May 2016-April 2017. Conductivity, pH, water temperature, and salinity were measured. The relationship between water characters and the seasonal abundance of zooplankton seasons was examined through regression analysis. Ciliates, Rotifers, Nauplius larva, Gammarus sp., Veliger larva, Nematodes, Planaria, Copepods, and Kinorhyncha were recorded for both study areas. The highest species richness and population density were recorded during the summer season for Almarjan sandy shore and Turfa peninsula mangrove. Ciliates were the most abundant zooplankton on the sandy shore, while Kinorhyncha was the least abundant. The zooplankton Nematode was the most abundant at the Turfa Peninsula mangrove, whereas Gnathostomulida was the least abundant. Conductivity, salinity, and water temperature showed a significant regression relationship (P<0.05) with zooplankton abundance. Data was discussed to highlight the role of zooplankton abundance in the mangrove and sandy shore ecosystem.

The present study was conducted on seasonal abundance of phytoplankton of prawn based carp polyculture system fishponds for a period of six months from September 2006 to February in the village Meherchandi of Boalia thana under Rajshahi district of Bangladesh. During the study period, it was found that water temperature varied from 16.59°C (T2) to 29.82 (T1), transparency 26.72 (T1) to 40.13cm (T2), pH 7.21 (T1) to 8.0 (T2) DO 2.13 (T2) to 3.6mg/l (T2), CO2 4.63 (T1) to 10.63mg/l (T2), NH3N 0.001 (T1) to 0.0197mg/l (T2) and total alkalinity fluctuated from 85.38 (T1) to 147.75mgl (T2). A total four groups of zooplankton were identified where 5 rotifera (38.41%) was dominant followed by 3 cladocera (31.49%), 2 copepoda (21.84%) and crustacean larvae (8.26%). It was also found that zooplankton showed abundance in February. The highest total average zooplankton (18390.79±2144.63 cells/l) was recorded in T1 than T2 which might be due to the effective uses by high stocking density of fishes. Zooplankton showed positive correlation with pH, DO, CO2 and alkalinity in T1. In case of T2, positive co-relationship was found with pH, DO, CO2 and NH3-N. The mean values of highest final weight of M. rosenbergii, H. molitrix and C. catla were 89.20±8.62g (T1), 682.70±44.20g (T2) and 428.00±4.50g (T1) respectively, highest survival rate was found 76.25±6.25% (T1) of prawn and highest total average yield was obtained 940.65±259.43 kg/ha in T2 due to high stocking densities of prawn.

Water is one of the most important natural resources which play an essential role in human life. Most of the Nigerian institutions stored water in either plastic or overhead tanks for different purposes. However, there has been a growing concern over the safety of the stored water for human consumption following reported cases of microbial occurrence in water stored in tanks. This study aimed at investigating the water quality stored in plastic tanks in Umaru Musa Yar’adua University Katsina. Water samples were collected from plastic tanks and analyzed for some physico-chemical and heavy metals parameters. The result of physico-chemical parameters obtained shows that only dissolved oxygen, biological oxygen demand and chemical oxygen demand were observed above the maximum permissible limit for drinking recommended by WHO and NSDWQ with the mean value of 55.18 mg/l, 38.86 mg/l and 38.08 mg/l respectively. While the remaining parameters such as pH, electrical conductivity, total dissolved solids, turbidity, total suspended solid, alkalinity, sulphate, nitrate, phosphate, chloride and total hardness were found within the acceptable limit. However, analyzed result of heavy metals parameters revealed that all parameters were observed within desirable limit by WHO and NSDWQ for drinking water and suggested that the quality of water stored in plastic tanks was very good. It is concluded that, the quality of water stored in plastic tanks is suitable for human consumption. It is therefore recommended that, continuous monitoring of the water should be maintain so as to ascertain the safety of the water
