Quantifying the effects of post-surgery recovery time on the migration dynamics and survival rates in the wild of acoustically tagged Atlantic Salmon Salmo salar smolts

Animal Biotelemetry, 2021
Background The experimental effects of surgically implanting fish with acoustic transmitters are likely to have negative effects on survival and behaviour.

Testing for broad-scale relationships between freshwater habitat pressure indicators and Pacific salmon population trends

Ecological Indicators, 2023
Global freshwater biodiversity is declining at rates greater than in terrestrial or marine environments, largely due to habitat alteration and loss. Pacific salmon are declining throughout much of their southern range due to a combination of pressures in

Feeding dynamics of the invasive calanoid copepod Pseudodiaptomus inopinus in two northeast Pacific estuaries

Aquatic Biology, 2022
The Asian calanoid copepod Pseudodiaptomus inopinus, first observed in the Columbia River Estuary in the early 1990s, has since become the dominant copepod species in many estuaries along the US Pacific coast, but its feeding behavior has not been ...

Deterministic Lateral Displacement (DLD) Analysis Tool Utilizing Machine Learning towards High-Throughput Separation

Micromachines, 2022
Deterministic lateral displacement (DLD) is a microfluidic method for the continuous separation of particles based on their size. There is growing interest in using DLD for harvesting circulating tumor cells from blood for further assays due to its low ...

Principles and Methods of Counteracting Harmful Salmon–Arthropod Interactions in Salmon Farming: Addressing Possibilities, Limitations, and Future Options

Frontiers in Marine Science, 2021
The arthropod salmon louse (Lepeophtheirus salmonis) is a major threat to Atlantic salmon aquaculture and wild salmonids. Essentially like in monoculture, very high concentrations of susceptible hosts may result in high reproduction and severe production

Jet Dynamics Associated with Drop Impact on Micropillared Substrate

Fluids, 2021
The jetting phenomenon associated with droplet impact upon a hydrophilic micropillared substrate was analyzed in detail using a high-speed camera. Viscosities of the fluids were varied using differing concentrations of glycerol in deionized water.
