Swimming Upriver? Exploring the Sources of Freshwater and Marine Fish in Military Diet in Sixteenth‐ to Nineteenth‐Century Northeastern North America

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Atlantic cod were caught in large numbers and shipped from fishing stations in North America to Europe and the Caribbean, and this has been frequently studied zooarchaeologically; however, the exchange of cod and other fish into interior North America has received less study.

Hybrid Modeling for In Situ Artificial Fish Spawning Ground Stabilization

River Research and Applications
ABSTRACTErosion generally reduces the resilience of replenished gravel in rivers. As a result, structures are sometimes added to modify the upstream flow and stabilize artificial spawning grounds. In particular, rows of boulders can be placed around the replenishment area to limit the transport of replenished gravel during flood events. This study aims

Chinese Sturgeon (Acipenser sinensis) in the Yangtze River: a hydroacoustic assessment of fish location and abundance on the last spawning ground

, 2006
Chinese sturgeon ( Acipenser sinensis), was once widely dispersed in almost all watersheds draining towards the western coasts of the Pacific Ocean. Today, the species is one of the highly endangered fish species in China and can be found only in the ...

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel

River Research and Applications, EarlyView.
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...

Development and Improvement of Habitat Suitability Criteria for Instream Habitat Assessments Conducted in Support of Environmental Flows in Florida

River Research and Applications, EarlyView.
ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...
