“…It further discusses how to develop and manage river ecological restoration measures to more comprehensively maintain river fish habitat quality at a high level in small and medium mountainous rivers. Compared with our previous research results in the Heishui River [ 23 , 40 ], this study is a continuation and extension of the research on the impact of external environmental changes on fish. The research results can provide theoretical support for the environmental impact assessment and adaptive management of subsequent river restoration projects.…”

“…The replenishment of fish populations is highly dependent on habitat availability and habitat quality [ 19 , 20 , 21 , 22 ]. Only when external environmental conditions such as water temperature, hydrology and hydraulic power are met and sufficient energy is accumulated can fish complete the corresponding life activities [ 23 , 24 ]. Spawning activity, which bonds parents and offspring and is believed to be key to boosting stocks, has been well discussed by scholars [ 25 , 26 , 27 , 28 ].…”

Dam removal is considered an effective measure to solve the adverse ecological effects caused by dam construction and has started to be considered in China. The sediment migration and habitat restoration of river ecosystems after dam removal have been extensively studied abroad but are still in the exploratory stage in China. However, there are few studies on the ecological response of fishes at different growth stages. Considering the different habitat preferences of Schizothorax prenanti (S. prenanti) in the spawning and juvenile periods, this study coupled field survey data and a two-dimensional hydrodynamic model to explore the changes in river morphology at different scales and the impact of changes in hydrodynamic conditions on fish habitat suitability in the short term. The results show that after the dam is removed, in the upstream of the dam, the riverbed is eroded and cut down and the riverbed material coarsens. With the increase in flow velocity and the decrease in flow area, the weighted usable area (WUA) in the spawning and juvenile periods decreases by 5.52% and 16.36%, respectively. In the downstream of the dam, the riverbed is markedly silted and the bottom material becomes fine. With the increase in water depth and flow velocity, the WUA increases by 79.91% in the spawning period and decreases by 67.90% in the juvenile period, which is conducive to adult fish spawning but not to juvenile fish growth. The changes in physical habitat structure over a short time period caused by dam removal have different effects on different fish development periods, which are not all positive. The restoration of stream continuity increases adult fish spawning potential while limiting juvenile growth. Thus, although fish can spawn successfully, self-recruitment of fish stocks can still be affected if juvenile fish do not grow successfully. This study provides a research basis for habitat assessment after dam removal and a new perspective for the subsequent adaptive management strategy of the project.

“…Prior research has indicated that various factors, such as alterations in hydrological conditions and habitat fragmentation induced by hydropower development in the middle and lower reaches of the Jinsha River, have significantly impacted the fishery resources in numerous sections of the river. This impact is notably observed in certain species, including the Coreius guichenoti, Rhinogobio ventralis, and Schizothorax prenanti, all of which held a dominant position in the pre-reservoir fish community structure of the Jinsha River [33]. Coreius guichenoti was selected as the target fish in this study due to its high sensitivity to flow and important economic value.…”

Hydropower operations significantly alter the natural hydrological conditions of rivers, exerting adverse effects on riverine ecosystems. Accurate identification of fish habitats under hydropower operation and maintaining suitable ecological flow are crucial for riverine ecological conservation and water resource management. Coreius guichenoti was selected as the target species and the Yibin reach of the downstream Jinsha River was selected as the studied river reach. Subsequently, Weighted Usable Area (WUA) and Habitat Connectivity Index (HCI) were employed to comparatively analyze the habitat quantity and quality before and after the construction and operation of the Xiangjiaba hydropower station, namely the natural period (1991–2005), construction period (2006–2014), and operation period (2015–2020). Finally, correlations between WUA, HCI, and flow were established to determine the optimal ecological flow corresponding to optimal fish habitats. The results indicate that the average WUA and HCI during the construction period are similar to the natural period. In comparison to the natural period, the average WUA decreases by 9.2%, and the average HCI decreases by 0.05 during the operation period. It is determined that the habitat conditions are optimal when the flow is between 3000 and 5000 m3/s. After further refining the flow scenarios, the suitable ecological flow is determined to be 3500 m3/s. This study can provide a scientific basis for the water resources management in the Jinsha River and contribute to the field of riverine ecological conservation and restoration.

“…Few studies have systematically quanti ed the ecosystem service potential of whole river ecosystems. A number have targeted only single services, such as nitrogen retention (Basak et al, 2021;Burgin et al, 2013;Vermaat et al, 2016); water quality (Gilvear et al, 2019;Keele et al, 2019;Stammel et al, 2021); water provision (Notter et al, 2012) and ood regulation (Asbjornsen et al, 2022;Hill et al, 2023;Liu et al, 2021). There remains a paucity of tools to assess and quantify the ecosystem services generated by often complex river reaches and stream networks (Palmer & Ruhi, 2019).…”

Riverine ecosystems supply humans with a variety of ecosystem services (ESs), but anthropogenic activities endanger their availability worldwide. Understanding the spatiotemporal characteristics of riverine ESs and identifying the primary driving forces behind various ESs are crucial for preserving regional ecological security and achieving ecosystem sustainability. The study examines the spatio-temporal changes from 2000 to 2022 in the Danro River Basin in Jharkhand in four essential Ecosystem Services (ES): Sediment Delivery Ratio (SDR), Nutrient Delivery Ratio (NDR), Habitat Quality Monitoring (HQM) and Carbon Storage (CS), using InVEST model, Land Use Dynamics Index and Correspondence analysis. Danro River is a tributary of the Ganges River basin affected by sand mining. Key results were: (1) A rise in soil erosion was observed due to the transformation of agricultural land into urban areas; (2) The phosphorous and nitrogen retention was higher in agricultural land as compared to forest areas; (3) The habitat quality of the Danro River body showed degradation during 2000 to 2020; (4) The study area can sequester 2128304.92 Mg of Carbon; (5) The land use dynamic index (K) indicated that bare ground experienced the greatest impact, with a value of -0.021. The study uncovered complex relationships between ecosystem services and land use changes, emphasizing tradeoffs and synergies and laying stress on the holistic management strategies to balance tradeoffs and leverage synergies. The findings provide valuable insights for decision-making in socio-environmental processes. Other regions missing meteorological, hydrological, and geological data may also benefit from applying the InVEST model with localized parameters.
