Why does turbidity decrease in wetland water after post-monsoon? 


Best insight from top research papers

Turbidity in wetland water decreases after the post-monsoon season. This decrease in turbidity can be attributed to several factors. One factor is the reduction in sediment influx due to decreased rainfall and runoff during the post-monsoon season . Another factor is the absence of large-bodied fishes in the wetlands, which can induce a shift from a turbid- to a clear-water state . The elimination of fishes during a drought can lead to a decrease in turbidity and an increase in plant cover in wetland ponds . These changes in wetland condition, such as decreased turbidity and increased plant cover, contribute to the overall decrease in turbidity in wetland water after the post-monsoon season .

What is the standard level of turbidity in fish pond?5 answersThe standard level of turbidity in fish ponds can vary based on the specific requirements of the aquatic species present. Research indicates that turbidity levels can significantly impact aquatic life. Studies have shown that high turbidity levels can reduce feeding rates in various fish species, while in ponds with naturally turbid conditions, the net weight of fish harvested per hectare per year varied depending on the turbidity levels. Additionally, the use of alum was found to effectively reduce clay turbidity in ponds, with specific application rates determined by an alum-requirement test. Therefore, maintaining an optimal turbidity level that supports the feeding behavior and growth of fish species is crucial for successful aquaculture management.
Standard level of turbidity in fish pond?5 answersThe standard level of turbidity in fish ponds can vary based on the specific requirements of the aquatic species and the management objectives. Research indicates that turbidity levels can impact various factors in fish ponds. Studies have shown that high turbidity can affect feeding rates of fish species, while in aquaculture and biofuel microalgae pond management, turbidity measurements can be correlated with parameters like chemical oxygen demand (COD). Additionally, the use of alum has been found effective in removing clay turbidity from pond water, with alum-requirement values ranging from 10 to 30 mg/liter in ponds containing clay turbidity. Therefore, the ideal turbidity level in a fish pond should be determined based on the specific needs of the aquatic species and the management goals.
Why does water quality index improves during post monsoon?5 answersThe improvement in water quality index during the post-monsoon period can be attributed to reduced pollution levels due to factors like decreased industrial activities and limited human movement, as observed during the COVID-19 pandemic. Additionally, the post-monsoon period typically sees better water quality grades compared to pre-monsoon and monsoon periods, as evidenced by studies on various physicochemical parameters like pH, electrical conductivity, total dissolved solids, dissolved oxygen, fluoride, sulphate, and total hardness. Furthermore, the weighted mean water quality index for both surface water and groundwater tends to be higher during the post-monsoon period, indicating an overall improvement in water quality. This improvement is also reflected in thematic maps showing a higher percentage of excellent water quality categories during the post-monsoon season compared to other seasons.
What is water turbidity?5 answersWater turbidity refers to the lack of clarity in water caused by suspended particles and microalgae that scatter light. It is an important characteristic of surface waters and wastewater treatment plant effluents, serving as a key indicator of water quality. Turbidity is measured by the amount of light scattered by the materials present in the water, with higher turbidity values indicating a higher concentration of suspended particles. While turbidity itself does not directly pose a health hazard, it can be an indication of poor water quality and can mask the presence of parasites such as Cryptosporidium. Therefore, it is recommended by the World Health Organisation (WHO) that turbidity should not exceed a certain level before chlorination. Efforts are being made to develop tools and methods to measure and reduce turbidity in water treatment processes.
Why do estuaries have high turbidity?4 answersEstuaries have high turbidity due to various factors. Turbidity is influenced by sediment transport and resuspension, which can be caused by multiple biogeochemical processes and sedimentation from rivers. Human activities and natural changes can also contribute to changes in estuarine water quality, including turbidity. Additionally, the presence of mud pools on the estuary bed and time-varying river discharge can affect the trapping of fine sediment and the formation of estuarine turbidity maxima (ETMs). In the availability-limited state, the SSC is limited by the amount of erodible sediment at the bed, while in the erosion-limited state, an abundant amount of sediment at the bed leads to sediment pickup at the maximum possible rate. These factors can result in the movement and distribution of sediment, leading to high turbidity in estuaries.
How does turbidity affect fish in rivers?4 answersTurbidity affects fish in rivers by reducing their ability to detect food, predators, and conspecifics. It can lead to risk-averse behavior, as fish take longer to leave a refuge, locate food, and consume less food in turbid conditions. Turbidity also affects predator-prey interactions, as prey survival, particularly of invasive species, is lower in turbid water in the presence of predators. Decreased water clarity caused by turbidity can affect the predation efficiency of native piscivores and increase the abundance of alien fish. Turbidity alters collective movement in fishes, leading to decreased collective behavior, increased interfish distances, and changes in group structure. Turbidity is strongly correlated with fish biomass, with salinity and turbidity being important seasonal drivers of fish abundance in certain communities. Turbidity levels up to 160 NTU do not affect the feeding rates of certain fish species, indicating their lower sensitivity to turbidity.
