“…Several previous studies in Bangladesh have reported similar zooplankton groups such as Cladocera, Rotifera, and Copepoda in pond water. 17,18,[32][33][34] The Lakshadweep Archipelago in India (56 species, 7 groups) and a man-made lake in Malaysia (27 species, 3 groups) had higher zooplankton communities than those in the present study, which can be attributed to diverse habitats. 35,36 The variation in zooplankton genera in the present study compared to other studies could arise from differences in the nutrient status, pond bottom, and embankment soil quality, meteorological factors, and the massive growth of phytoplankton in pond water.…”

“…Zooplankton community distribution within water bodies varies with time due to their proficiency in quick response to even slight environmental changes and vertical migration, which is an almost universal phenomenon. 17,40 Previous research findings claimed that zooplankton distribution is non-homogenous in limnetic waters and probably related to food availability and avoidance of predators. 2…”

“…The zooplankton communities in a pond determine aquaculture's productivity. 17 In eutrophic freshwater fish ponds in Bangladesh, zooplankton is particularly prevalent and highly sensitive to environmental changes in water bodies. The physicochemical variables such as temperature, pH, DO, total alkalinity, free CO 2 , water depth, light, and nutrient status 18 are the principal parameters affecting the presence, composition, and abundance of particular zooplankton in fish ponds.…”

“…19 Aquatic nitrogenous and phosphorus nutrients also regulate the diversity and distribution of zooplankton. 20 Some scientific research has been done in different ponds and lakes in Bangladesh, 2,17,18 although none of these investigations has thoroughly explained the existence, quantity, and seasonal dynamics of zooplankton. To make the fisheries sector sustainable and safe, extensive research is required on the aquaculture inputs used in ponds, influential environmental factors, and their effects on zooplankton.…”

Zooplankton is crucial for transmitting energy from primary producers to higher trophic levels. A study was done in a Bangladesh eutrophic fish pond to know zooplankton's seasonal dynamics in relation to environmental factors. There were 11 different zooplankton genera, which belong to three major classes: Copepoda, Rotifera, and Cladocera. Peak abundance of zooplankton was found in the spring and winter, respectively. Cluster analysis clearly indicated zooplankton abundance during the spring and winter. Rotifera was the main dominant group in the total zooplankton population. Copepoda and Cladocera had a lower abundance than those of Rotifera. During the study period, environmental factors were observed monthly. The total zooplankton abundance showed a positive correlation only with pH and a negative correlation with transparency, dissolved oxygen, phosphates, nitrates, and temperature during Pearson’s correlation coefficient analysis. The canonical correspondence analysis also indicated that pH, transparency, and temperature significantly affect the abundance of zooplankton groups. Therefore, further research on the influence of environmental factors on different species of zooplankton is strongly suggested for achieving sustainable fish production from eutrophic fish ponds.

“…Since the first time spread in the pond, samples were taken every 10 days for 8 weeks based on the day of culture (DOC) of Pacific white shrimp. Plankton was collected on the pond water surface using a plankton net (mesh size: 25 µm) and preserved in 5% buffered formalin at 250 mL of sterile plastic [24].…”

This study aimed to evaluate plankton in Pacific white shrimp (Litopenaeus vannamei) cultivation in Bulukumba Regency, South Sulawesi. The study was conducted in six intensive ponds for 84 days from November 2019 to February 2020. Plankton samples were collected every 10 days for 8 weeks based on the day of culture (DOC) of Pacific white shrimp since the first rearing in the pond using plankton net (mesh size of 25 μm). Then, planktons were preserved to 5% formalin buffer in 250 mL of sterile plastic. Next, the plankton densities and compositions were analyzed quantitatively and qualitatively. The results showed that plankton dominance in Chlorophyta species and the presence was evenly distributed across all shrimp ponds in the field. The number was relatively stable in all shrimp DOCs and was the highest proportion as well; Chlorophyta (73 to 83%), Diatom group (7.75 to 15.63%), and blue-green algae (BGA) group (7.13 to 13.50%). Plankton can be used as a biomonitor of pollution and shrimp health in dominance and the percentage proportion of each species. Regular monitoring is highly recommended to minimize plankton growth, especially the BGA type that can harm shrimp health in the intensive system.

Abstract. Khan NS, Islam MS, Bari JBA, Uddin M, Mashkova I, Kostryukova A, Trofimenko V. 2023. Deterministic assessment of the ecological vulnerability of coastal freshwater canals: A perspective on social awareness and conservation. Biodiversitas 24: 5179-5188. Inland freshwater canals are formed by geomorphological evolutions or artificially for communal welfare. The freshwater canal ecology differs mainly from rivers, estuaries, and the ocean for salinity variables, nutrient concentrations, morphological structure, and unique flora and fauna distribution. These canals and their aquatic organisms are very sensitive to surface runoff and direct sewage pollution. Thus, these freshwater canals become threats to society in case of contamination. The current study focused on the water quality, microalgae, and zooplankton communities in two renowned canals: Basurhat (BH) canal and Dotterhat (DH) canal in coastal Noakhali, Bangladesh. The study attempted to demonstrate these canals' aquatic and ecological status by evaluating plankton distribution and some important water quality parameters. Furthermore, a classic Palmer's algal organic pollution Index and wetland zooplankton Index were applied to determine the water quality according to species assemblages of freshwater algae and zooplankton, respectively. The present study identified 27 phytoplankton genera from Bashurhat Canal and 21 from Datterhat Canal. At the same time, 16 genera of zooplankton were observed with 2,269.09±52.12 ind/L and 4,588.54±40.79 ind/L from Bashurhat Canal and Datterhat Canal, respectively. The water quality differed from Bashurhat Canal and Datterhat Canal, where the highest temperature was found at Bashurhat Canal at 23.55±0.15°C and the lowest was 22.6±0.1°C. Moreover, the highest and lowest temperature was found from Datterhat Canal as 29.8±0.9°C and 29.67±0.78°C respectively. The highest transparency (cm), Dissolve Oxygen (mg/L), alkalinity (mg/L), free carbon dioxide (mg/L), ammonia (mg/L) and TSS (mg/L) were found as 29±1.0, 1.25±0.25, 58.76±0.26, 59.25±0.66, 8.25±0.25, 2.25±0.05 and the lowest were found 20.5± 0.5, 0.75±0.25, 27.73±0.49, 11.28±0.69, 8.15±0.15, 2.2±0.1 in Bashurhat Canal. Additionally, the highest transparency (cm), Dissolve oxygen (mg/L), alkalinity (mg/L), free carbon dioxide (mg/L), ammonia (mg/L), and TSS (mg/L) were found as 15.75±0.25, 1.85±0.50, 53.96±0.5, 55.09±0.8, 8.1±0.1, 4.0±0.1 and the lowest were identified 14.5± 0.5, 1.25±0.25, 23.1±0.4, 49.23±0.38, 7.65±0.50, 2.54±0.75 in Datterhat Canal. The study results indicate the deterioration of water quality in urbanized canals and that aquatic ecosystems face many long-term anthropogenic pressures. The current canal state requires measures to restore them. In addition, there is a need for strict control over the discharge of waste and pollutants from residential areas, fish markets, and hospitals.
