The present study was conducted from April 2016 to March 2017 in a freshwater-dominated coastal wetland of the Indian Sundarban ecoregion to illustrate the fish diversity, and abundance and the predictor variables determining fish assemblage structure in the wetland. A total of 27 fish species belonging to 13 orders, 16 families, and 23 genera with Cyprinidae (18.5%) as the most dominant family were recorded from the wetland.

Article Synopsis
- Fish are key indicators of ecological health, and a study monitored their habitat in the Ganga River between July 2021 and July 2022 to assess environmental restoration.
- The research focused on the fish Gudusia chapra, tracking their food sources and physiochemical conditions using various pollution indices, revealing a significant increase in fish catch and a decrease in pollution levels.
- Analyses showed that factors like water velocity, transparency, and oxygen levels critically influence the fish species, highlighting the importance of these environmental variables for their habitat quality.
Article Synopsis
- Growing human populations and climate change are significantly harming water quality, particularly in vulnerable ecosystems like freshwater wetlands, which are increasingly polluted with heavy metals.
- A study evaluated the impact of natural floating islands designed as fish aggregating devices (FADs) using native weed mass on heavy metal distribution in these wetlands, finding significant reductions in heavy metal concentrations in the water and fish within the FADs.
- The research highlights the potential of natural floating islands to improve water quality and reduce health risks associated with metal pollution, thereby supporting the sustainability of freshwater ecosystems and benefiting human health and livelihoods.
Anthropogenic activities impacted the ecological health of rivers by altering the physical habitat and water flow as well as by pollution. Monitoring of biotic groups for gauging the river health is a prerequisite for assessing the extent of degradation and formulating management guidelines for river restoration. An assessment using fish-based index of biotic integrity (IBI) was carried out in the Central Indian river, Tapti, for probing its health status.

This study aims to identify Aeromonas species harbouring virulence genes aerolysin, flagellin, and lipase from diseased fishes of Assam wetlands with association with antibiotic resistance and in vivo pathogenicity.
