“…Multiple regression analysis of the influence of anthropogenic loads in basins on the taxonomic composition, abundance and age of ichthyofauna, LFI, in the water showed that the LFI values were influenced by the current percentage of organic farms in the basin, and such trends have been evaluated by other researchers [49]. It should be noted that this variable is also influenced by seasonality, water body structure [50] and anaerobic substances [51]. Research shows that organic farming can improve surface water quality [33].…”

Twenty-six water bodies and 10 ponds were selected for this research. Anthropogenic loads were assessed according to pollution sources in individual water catchment basins. It was determined that 50% of the tested water bodies had Ntotal values that did not correspond to the good and very good ecological status classes, and 20% of the tested water bodies had Ptotal values that did not correspond to the good and very good ecological status classes. The lake basins and ponds received the largest amounts of pollution from agricultural sources with total nitrogen at 1554.13 t/year and phosphorus at 1.94 t/year, and from meadows and pastures with total nitrogen at 9.50 t/year and phosphorus at 0.20 t/year. The highest annual load of total nitrogen for lake basins on average per year was from agricultural pollution from arable land (98.85%), and the highest total phosphorus load was also from agricultural pollution from arable land (60%).

“…Major activities in the catchments of both lakes include; intensive agriculture, habitat for birds, cattle and orchards. These lakes are subjected to culture based sheries management practices involving stocking of both indigenous and exotic carp seed to provide livelihood support to the 500 and 300 shers families, respectively (Meena et al, 2019). Both the lakes are located in the lower Gangetic deltaic regions that subjected to the in uence of runoff from agricultural land and domestic wastes, silt materials from the catchment due to jute retting, bathing, washing etc.…”

“…A number of wetland health assessment tools have been applied i.e. macrobenthos based multimetric indices (Meena et al 2019), phytoplankton indices (Roshith et al 2018), water quality index (WQI) (Sharma and Bora, 2020), biomonitoring and bioassessment (Sanyal et al, 2015), sh assemblage and sheries (Sandhya et al, 2016;Sandhya et al, 2019) etc. They have limitations in terms of real time application such as high uctuations due to climatic and water quality factors.…”

In recent years closed and seasonally open oxbow lakes and river floodplains are subjected to eutrophication due to disconnection from river that compromises the hydro-ecological functions. This requires systematic studies to assess the ecological health of the water bodies using different indices and suggest appropriate strategies to manage the resources. The zooplanktons are closely link with surrounding environment throughout their life cycles and change rapidly in their growth and population when changes occurs in the surrounding, hence act as potential indicator of eutrophication. The present study examined the assemblage pattern of zooplankton community and trophic state of two ecologically distinct oxbow lakes based on eco-hydrological characteristics and community structure of rotifers and planktonic crustaceans seasonally over a period of 2 years. Comprehensive trophic state index (mTSI), rotifer trophic state index (mTSIROT) and Crustacean based indices (TSICR) were used to assess the degree of eutrophication. The Kruskal-Wallis test confirmed the heterogeneity of the eco-hydrological factors between the oxbow lakes. A total of 68 zooplankton species were identified of which rotifers (69%), cladocerans (18%), copepods (3%), ostacods (3%) and protozoans (7%). Seasonal fluctuation of relative abundance and frequency of species in both lakes have been well presented. Both lakes showed transition from high meso-eutrophic to moderately eutrophic state with mTSI, mTSIrot and mTSIcr values of 54.90±11.71 and 56.95±15.64, 59.55±4.54 and 60.26±4.48, 55.79±4.76 and 60.00±4.03 in Khalsi (seasonally open) and Akaipur (closed) respectively. The Canonical Correspondence analysis (CCA) revealed water quality parameters comparison NO3-N, water temperature and pH have contributed more in enhancement of abundance of eutrophication indicator species Brachionus and Keratella. The TSIs values indicated a prompt aquaculture fisheries management measures like stocking of planktivorous fish (Labeo catla and Puntius sp.) for both the lakes before they reach in plunged state at which their restoration might become a challenge. An overview of worldwide use of rotifer and crustacean based indices in assessment of TSI has also been synthesized. The use of these zooplankton indices to evaluate the trophic status of the ecologically distinct lakes is highly recommended for water quality assessment and management. Based on this study strategies could be developed to plan and manage floodplain oxbow lakes for fisheries enhancement programme as well as as conservation of biodiversity.

With the rapid improvement of my country's industrialization process, the unreasonable use of water resources, deforestation, vegetation destruction and other phenomena frequently occur, especially the poor public awareness of environmental protection, lack of awareness of the protection of water resources in the Qinghe River, etc. Decline. Studying the Qinghe water environment based on the macrobenthos community biological index can provide a strong scientific basis for the management of the Qinghe water environment. The purpose of this paper is to comprehensively evaluate the water environment of Qinghe River based on the biometric index of macrobenthos community. During the experiment, samples were collected and analyzed for the sample collection method, namely direct hand net sampling in shallow rivers and foot manipulation in deeper water. Using the BI index method, the spatial distribution of macrobenthos species and the fuzzy comprehensive health assessment of the Qinghe water environment were investigated and analyzed.
