“…Zooplankton and finfish consume phytoplankton as food and form a part of the marine ecosystem (Kumari et al, 2023). Any change in the environment causes a change in the presence, absence, abundance, and distribution of the phytoplankton species of a particular environment (Piranti & Wibowo, 2021), and the species respond quickly to any change in the environment (Thakur et al, 2013).…”

“…The presence of planktonic organisms in their natural environments is dependent both on abiotic environmental factors (temperature, dissolved oxygen [DO], and pH) and biotic interactions among the organisms themselves. Tolerance ranges, also known as ecological optimums, are related to the presence of planktonic organisms (Kumari et al, 2023). The presence or absence of species in a multidimensional space known as an ecological niche is influenced by a large number of environmental factors, including both non-human and anthropogenic influences.…”

Bioindicators have become increasingly popular and have contributed significant amounts of useful information to the process of managing water resources. The ability of a species (or species assemblage) to adapt to a certain range of chemical, physical, and biological conditions is one criterion that can be used to assess the quality of its surrounding environment. Planktons that react quickly to changes in their environment have proven to be particularly valuable, and the identification of certain indicator species has become increasingly common in the process of determining the quality of the water. The “health” of an aquatic system can be inferred from the presence or absence of plankton, which act as early warning signals. When compared with the expense of assessing harmful contaminants, the overall cost of conducting routine monitoring of biological communities is far lower and has a higher degree of reliability. The ability of bioindicators to identify indirect biotic effects of pollutants, which is something that many physical or chemical tests are unable to do, is another advantage of using bioindicators. Different aquatic species as bioindicators tolerate different environmental conditions, and their different tolerances to particular environments help in identifying a particular environmental condition. Phytoplankton species like Euglena viridis, Oscillatoria limosa, Nitzschia palea, and Scenedesmus quadricauda, and zooplankton species like Branchionus sp., Molina sp., Keratella cochlearis, Daphnia sp., and Cyclopus sp. indicate water pollution. This review's objective is to highlight some recent research on planktons, focusing on their capabilities and opportunities for application as bioindicators of water quality.

“…The aim of water policy in India is to effectively manage and utilize water resources to ensure sustainable development, equitable distribution, and improved water security for all citizens (Kamboj et al, 2022a(Kamboj et al, , 2022b. The overarching goal is to address the complex challenges related to water scarcity, pollution, and inefficient water management practices (Kumari et al, 2023;Thakur et al, 2022). The specific objectives of water policy in India can vary over time as they are influenced by the prevailing socioeconomic and environmental conditions.…”

Several natural and anthropogenic activities, as well as rapid urbanization and industrialization, have caused freshwater bodies and their water quality to deteriorate rapidly over the past two decades. This study utilizes ArcGIS to map water quality parameters in the Baner and Gaj rivulets, tributaries of the river Beas in Himachal Pradesh, with the objective of gaining insights into their potential impact on the main river. So, the main aim of the present research was to assess the impact of anthropogenic actions on the ecology and the fitness of the rivulets basin to perpetuate freshwater diversity. A total of six sampling zones were selected; three sampling zones on Baner and three sampling zones on Gaj rivulets, in order to assess the water quality during the period of one year, from January 2022 to December 2022. During the present study, the Water Quality Index (WQI) was used to assess the status of water quality in both rivulets. Fourteen physicochemical parameters were examined using appropriate techniques and then compared to international standards. A slight upsurge was observed in some physicochemical parameters, such as pH, hardness, TDS, nitrate, and phosphate, at sampling zone 3 (S3) of the Baner rivulet. The results of WQI ranged from 45.5 at S1 to 50.2 at S3 in Gaj and 48.5 at S1 to 55.2 at S3 in Baner, which reflected a slight impact of natural and anthropogenic activities. The status of the water quality in both rivulets confirmed the abundance of aquatic species. Human activities, such as riverbed mining, also negatively impacted the water quality at some sample zones. There is, however, a need to monitor and evaluate these types of activities. However, further research and monitoring are necessary to validate the study's findings and extend its scope to other regions.

Poison in the water: Arsenic's silent assault on fish health

Arsenic occurs across the world in freshwater and marine environments, menacing the survival of aquatic organisms. Organic and inorganic forms of this substance can be found, in which the inorganic form is more hazardous than the organic form. Most aquatic bodies contain inorganic arsenic species, but organic species are believed to be the dominant form of arsenic in the majority of fish. Natural and anthropogenic both are the sources of water contamination with arsenic. Its bioaccumulation and transfer from one trophic level to another in the aquatic food chain make arsenic a vital environmental issue. Continuous exposure to low concentrations of arsenic in aquatic organisms including fish leads to its bioaccumulation, which may affect organisms of higher trophic levels including large fishes or humans. Humans can be exposed to arsenic through the consumption of fish contaminated with arsenic. Hence, the present review facilitates our understanding about sources of arsenic, its bioaccumulation, food chain transfer, and its effect on the fish health. Also, “Poison in the Water: Arsenic's Silent Assault on Fish Health” serves as a wake‐up call to recognize the pressing need to address arsenic contamination in water bodies. By understanding its devastating impact on fish health, we can strive to implement sustainable practices and policies that safeguard our precious aquatic environments and ensure the well‐being of both wildlife and human communities that depend on them.
