Summary: Knowledge of the geographic genetic structure of exploited and endangered species is crucial for sustainable management. In this study, the genetic structure of lake sturgeon across their Canadian range was analyzed using microsatellite loci. The results revealed two ancestral groups that originated from different glacial refugia. The patterns of genetic relationships among contemporary populations largely reflect colonization histories and connections within primary and secondary watersheds.

Summary: Using mixed stock analysis, we estimated population-specific occupancy of lake sturgeon in open-water and nearshore regions of Lake Michigan, and found differences in the mixture composition between the eastern and western basins of the lake. Significant heterogeneity in habitat occupancy was observed at microgeographic scales in open-water regions of Green Bay, indicating a preference for regions proximal to natal streams. Estimates of relative recruitment levels indicated increasing recruitment trends for spawning populations associated with Wisconsin tributaries.

Summary: The study determined the necessary flow conditions, quantity, and duration for lake sturgeon to successfully spawn and disperse larvae. It also evaluated juvenile sturgeon recruitment in relation to flow, tracking spawning migrations using telemetry receivers. Results showed that fluctuating or delayed spawning flows could result in restricted or delayed access to the spawning site.

Summary: Knowledge about critical habitats, such as spawning sites, is crucial for the conservation of vulnerable fish species like sturgeons. This study reviewed various sources of information to synthesize the available knowledge on lake sturgeon spawning sites in the Lower St. Lawrence and Ottawa river systems. The findings suggest that lake sturgeon populations in these river systems rely on multiple spawning sites, and expanding natural spawning grounds may be more effective than creating new ones.

Summary: This study investigated the long-term effects of gravel additions at eight sites in three rivers in western Norway over a period of up to 18 years. Results showed that gravel additions significantly increased juvenile densities of Atlantic salmon and Brown trout, with egg survival rates remaining high. However, the areas covered with gravel were shrinking over time. Construction costs for the gravel augmentations were relatively low, with a cost-benefit ratio that indicated the measure was successful in enhancing salmonid fish reproduction.

Summary: This study examined the suitable habitat for lake sturgeon in the Maumee River, Ohio and developed a suitability index model to evaluate habitat quality and quantity. The model results indicated that the Maumee River has suitable habitat for spawning adults and age-0 fish, supporting the reintroduction efforts for lake sturgeon in the area for the first time.

Summary: The Lower Fox River, a tributary of Green Bay in Lake Michigan, hosts a remnant Lake Sturgeon population. While reproduction has been confirmed, concerns remain about the long-term viability of the population. The study aimed to identify impediments to population growth and recovery by describing spawning habitat, determining the size and structure of the spawning stock, and quantifying larval production.

Summary: Lake sturgeon are endangered in the Laurentian Great Lakes, prompting increased efforts to establish spawning grounds. Passive acoustic monitoring was used to quantify spawning sounds, with drums identified as a marker for spawning activity. The research shows promise for mapping sturgeon spawning activity and highlights the potential impact of human activities on communication in the species.

Summary: The study analyzed the ecological conditions of degraded and remnant reefs in Saginaw Bay, as well as the spawning patterns of walleye and lake whitefish at these sites. While spawning fish utilized multiple sites, low densities indicated that the study sites were not major spawning locations.

Summary: This study emphasizes the importance of identifying and maintaining spawning grounds for herring in Scotland, particularly on the west coast. The research highlights the lack of knowledge regarding the exact location and environmental status of historic and contemporary spawning grounds, and calls for including these essential habitats in herring management plans.

Summary: This study evaluates the impact of compensatory measures implemented during the construction of the Baixo Sabor Hydroelectric Scheme on the survival and reproduction of the Iberian barbel. The results show that increased flow velocity and the installation of weirs improved fish migration and spawning, highlighting the effectiveness of restoring fragmented tributaries as a compensatory procedure.

Summary: Extensive monitoring has been conducted in the St. Clair - Detroit River System over the past two decades to understand the spatial and temporal patterns of lake sturgeon. This study focused on the juvenile lake sturgeon and identified hot spots in the system, providing valuable information for conservation and restoration strategies.

Summary: Lake littoral zones with abundant submerged vegetation are important spawning grounds for fishery resources. However, human activities have led to a decline in submerged vegetation, causing a loss of spawning grounds. This study explores the construction of artificial spawning grounds in lakes using artificial substrates. The results show that complex and dense three-dimensional artificial substrates can enhance fish recruitment. The findings also provide guidance for the deployment of artificial spawning grounds in terms of time and space.

Summary: Rocky reef habitats in lacustrine systems are important for lithophilic-spawning fishes, but may lose benefits if interstitial spaces are filled or blocked. Cleaning devices can increase substrate hardness and egg deposition, but effectiveness may depend on the magnitude of site-specific degradation.

Summary: The Maumee River watershed in the Great Lakes Basin has been impacted by pollution and habitat modification, leading to the designation of the Maumee Area of Concern. Assessments of fish and invertebrate communities identified areas of high biodiversity and habitats in need of protection or rehabilitation. Results suggest that areas with large island complexes in shallow water habitats have the highest fish diversity.

Summary: Lake Erie walleye recruitment has been affected by changes in food web, with young walleye adapting their diet and size accordingly. Comparing the diets of young walleye in 2019, 2014, and 1994-1999, it was found that their prey preferences changed over time. They have also started consuming invasive species in recent years. While changes in diet and size could impact their survival, it may not be significant if alternative prey is available.
