Summary: The study found that the success rate of Atlantic salmon migration through standing waters is generally low, possibly due to a lack of navigational cues. The impact of impounded lakes on Atlantic salmon migration is not significantly different from that of naturally draining lakes, and may depend more on factors such as lake basin shape, exit route, and navigational cues available to the fish.

Summary: This study evaluated the impacts of barriers, including dams, on aquatic diversity, finding that downstream areas of dams had higher mussel diversity than dam removal sites. Mussel assemblages were influenced by dam type and downstream gradient. Substrate classes and total suspended solids were identified as important predictors of mussel assemblages.

Summary: The study investigates the effectiveness of using wedges on the proposed stepped design in reducing drowning risk at the Salmon Dam in Ontario, Canada, which controls the immigrant sea lamprey population in the Great Lake of Ontario. It was found that optimal wedge placement reduces the dangerous vertical roller area from 27 to 83% of the tailwater depth area.

Summary: American eels passing through hydropower dams in the Penobscot River in Maine, USA face lower survival rates and higher mortality risks compared to undammed river sections. The fish also experience long delays at dams, especially under low flow conditions which exacerbate the risks of mortality and delay.

Summary: The study found that the existing fish weir had varying levels of survival and passage proportions for Chinook salmon, while being consistently effective for steelhead. Therefore, different passage solutions need to be developed for different fish species based on their specific needs.

Summary: A combined method of imaging sonar and underwater cameras was used to assess the population of adult Atlantic Salmon and Striped Bass in a tributary of the Miramichi River in Canada. The method estimated the number of fish based on the species ratio obtained from the underwater camera data. The results showed that the combined method provided accurate and timely information on the fish population in the river.

Summary: The study compared the prevalence of trypanosomosis in cattle between two districts, showing significantly higher infection rate in Kindodidaye compared to Loma. Various factors were considered, with season, district, Kebele, and body condition score showing significant differences in infection rates.

Summary: The study showed that Atlantic Salmon faced challenges in their spawning migrations due to obstacles in the form of hydropower generation stations and reservoirs. Migration rates were slower in the reservoir compared to upriver, with a significant portion of the tagged salmon experiencing delays in their journey. Further research is needed to determine the most effective management strategy for maximizing survival and spawning success in similar reservoirs.

Summary: Observations on the migration of Atlantic salmon in a river regulated by hydropower showed varying survival rates for kelts in winter and spring, with higher mortality among males. After passing through the dam, survival rates decreased significantly. Migration delays likely stemmed from searching behavior due to low water flow, impacting migration success.

Summary: The Striped Bass fishery in Miramichi River has been reopened for 13 years with new concerns raised about mercury levels in fish for human consumption. Mercury levels in some individuals are close to or exceed consumption guidelines. Angler surveys show that only a small percentage of anglers retain their legal catch limit, with some catching oversized fish.

Summary: Research shows that Atlantic salmon exhibit distinct habitat use patterns under different temperature conditions, with key parameters including boulder proximity, depth, velocity, and Froude number during normal temperatures, and proximity to cool thermal plumes and Froude number during thermoregulation events. Additionally, a unique geometric formation called a thermal-peloton was observed during behavior thermoregulation, reducing hydraulic drag and individuals' energetic expenditure. These findings provide valuable insights for Atlantic salmon restoration work and highlight the potential for UAV-based sensors to revolutionize river sciences.

Summary: The study found that the complexity of hydrogeological settings can affect river temperature prediction, and the Random Forest model can better cope with these complexities, providing higher accuracy in predicting river temperatures. During the study, thermal habitat changes for Atlantic salmon and brook trout were observed, indicating that some areas are unsuitable for these fish based on different temperature thresholds.

Summary: Coastal lagoons are important nursery habitats for marine fishes, but human activities can impact their water quality and the fish species that reside there. This study investigated the nutrient uptake and mercury levels in three common fish species in two lagoons on the central Mexican coast. The results showed that the lagoon with high wastewater inputs had higher mercury levels in fish, indicating the impact of human activities on these lagoons.

Summary: Continuity and discontinuity are fundamental concepts in ecosystem science. Different hydrological domains, such as surface water, soil moisture, rock moisture, and groundwater, can expand and contract, affecting connectivity. In order to reconcile these concepts, we propose a view of water-connected ecosystems and introduce the waterscape continuum template (WCT) to guide ecosystem research.

Summary: The presence of built structures in rivers can have significant ecological consequences, particularly in terms of fish passage. A holistic and adaptive approach is needed to address these barriers and develop successful fish passage management plans that consider the entire river ecosystem.

Summary: Damming of a river can alter the accumulation of sediment-bound elements, food web dynamics, and the chemical composition of fish. This study found that the dam altered the uptake of contaminants and nutrients by fish, indicating the importance of location and species when considering the risks and benefits of consuming wild fish from an impacted system.
