“…It may be attributed to the effect of post‐monsoon season's lower mean water temperature on gas solubility and retention and the mixing of monsoon rainfall during the monsoon and post‐monsoon seasons. Similar results were found by Singh and Rai (1999) in the Ganga River; Hiware and Jadhav (2001) in the Manjar River; Rafeeq and Khan (2002) in the Godavari River; Tamot and Mishra (2008) and Johnson et al (2021) in the Halali Reservoir; and Koushlesh et al (2022) in the Sardar Sarovar reservoir. Winter dissolved oxygen saturation in Finland boreal rivers has affected the fish assemblages as reported by Sutela et al (2010).…”

“…In addition, Koushlesh et al (2022) found that the total alkalinity (96 mg/L) and total hardness (128 mg/L) levels of the Sardar Sarovar reservoir (portion inside the territory of Madhya Pradesh) were lower in the post‐monsoon and higher in the monsoon (127 mg/l and 134.45 mg/L) season. On the contrary, Johnson et al (2021) observed higher total alkalinity levels in the post‐monsoon period (134.66 and 118.0 mg/L) and the lower levels in the pre‐monsoon period (87.33 mg/L) in Halali reservoir, while Saha et al (2021) reported lower values in the monsoon period (33.2 mg/l) in Mettur reservoir. Sulphates and chlorides cause permanent hardness, while carbonates and bicarbonates cause transitory hardness (Kumari et al, 2019; Saha et al, 2021).…”

“…While Das and Nandi (2001) in the oxbow lake of the Ichhamati river basin and Kumari et al (2019) in the Motia Lake had detected that pH levels were higher in the post‐monsoon season, these findings are similar to those of the current study. However, Tamot and Mishra (2008), Yousuf et al (2012) and Johnson et al (2021) noticed that high levels of pH during pre‐monsoon season in the Halali reservoir of Madhya Pradesh, India.…”

“…According to Negi and Mamgain (2013), the water and air temperatures have a significant impact on the fish aggregation and dispersal pattern, which was showing to be the greatest predictor of total abundance (Pombo et al, 2005). Environmental parameters such as DO, pH, nitrate and phosphate have an impact on fish distributions and assemblage composition in Halali reservoir and Bishalakhi Canal and the Bhetkimari Canal (Gogoi et al, 2022; Johnson et al, 2021), respectively.…”

“…However, the dominant changes found in five water quality indicators, such as water transparency (0.83–2.69), dissolved oxygen (4.43–6.83), total hardness (64.11–70.33), conductivity (188.25–261), phosphate (0.08–0.12) and chlorophyll‐a (2.84–4.24), were used to assess the intra‐annual comparison of environmental variables (Table 5). Total hardness, transparency, dissolved oxygen, chlorophyll‐a, phosphate and conductivity are all indicators of the state of the water and can be used to assess water quality and production (Johnson et al, 2021; Paul et al, 2017; Ramya et al, 2021; Saha et al, 2021).…”

Influence of seasonal variations in environmental parameters on fish assemblage and species diversity patterns was studied in a tropical reservoir of Central India during March 2021 to February 2022. A total of 41 species belonging to 7 orders, 15 families and 29 genera were recorded with highest diversity during post‐monsoon season compared to the pre‐monsoon season and monsoon season. The fish abundance similarity between the monsoon and post‐monsoon reached a maximum of 89%. Seasonal variations in the mean species abundance, Simpson dominance index, Shannon diversity index, Pielou's evenness index and Margalef's richness index were determined. One‐way ANOVA revealed a significant difference (P < 0.05) at the temporal scale. There was a significant seasonal difference in species abundance (P = 0.0006) and evenness index (P = 0.02) among the diversity indices. During the study period, three ‘vulnerable’ species, three ‘near threatened’ species and two ‘endangered’ species were caught. Carnivore dominance was evident throughout the year in the trophic guild of fishes. The Pearson correlation test revealed that water pH, dissolved oxygen, sediment organic carbon and clay percentage were positively correlated to all four diversity indices. Simpson and Margalef species richness diversity indices were positively correlated to sediment pH. Fish abundance was positively associated with sediment pH, silt, phosphorus and nitrogen content. Canonical correspondence analysis was used to investigate the relationships between fish assemblages and environmental conditions. Among the 19 physicochemical parameters, nine (dissolved oxygen, total dissolved solids, conductivity, transparency, hardness, phosphate and chlorophyll‐a, sediment nitrogen and phosphorus) characteristics were shown to be statistically significant (P < 0.05) in determining fish diversity. Dissolved oxygen, total dissolved solids, conductivity, transparency, hardness, phosphate and chlorophyll‐a of water and sediment nitrogen and phosphorus qualities were the key factors for the species abundance. The reservoir boasts a diverse fish population that allows multi‐species fishing and generates revenue for numerous local fishers. Fish habitats should be protected in order to maintain diversity and long‐term ecological benefits.
