Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,

Distortion Performance of Underwater Acoustic Sensor Networks
The paper studies the distortion performance of multihop underwater acoustic sensor networks. The network is composed of bottom mounted sensor nodes and the sensor to sensor links experience Rician fading. The distortion is evaluated for the case when there is interference from other sensors in the network.

Fish welfare in a changing world: New developments and current challenges
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Abstract Introduction In response to the decline of eastern oyster (Crassostrea virginica) populations in Chesapeake Bay, a large‐scale restoration initiative was launched in Harris Creek, Maryland, in 2011. This effort marked a shift from fragmented projects toward a coordinated, sanctuary‐based approach to oyster restoration.

Efficient Message Delivery in Underwater Acoustic Networks
The ideal tool for making underwater applications viable is an Underwater Acoustic Network (UAN). Unique characteristics, such as long propagation delay of the acoustic signal and extreme volatility in the channel quality, make UANs different from terrestrial radio networks.

This study evaluated the efficacy of an ultrasound pre‐treatment applied to a complex cereal–milk infant formula prior to conventional spray drying to mitigate inherent stickiness and yield challenges. Acoustic cavitation (30–90 s) significantly reduced suspension viscosity and improved atomization efficiency, elevating powder recovery yield from 12 ...
