Examining the Impact of Derelict Pots on Blue Crab (Callinectes sapidus) Catch and Harvest Within a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

Two-dimensional patterns with distinct differences; constructions, bounds, and maximal anticodes [PDF]

, 2010
A two-dimensional (2-D) grid with dots is called a configuration with distinct differences if any two lines which connect two dots are distinct either in their length or in their slope.

Delphi consensus: First‐line use of biologics and small molecules in hidradenitis suppurativa

Journal of the European Academy of Dermatology and Venereology, EarlyView.
This Delphi Consensus study identified upgrade criteria for the use of biologics and small molecules as first‐line therapy in hidradenitis suppurativa (HS). European HS experts evaluated 16 clinical scenarios, voting on eligibility for therapy escalation.

Rapid increase in abundance and distribution of invasive pink salmon (Oncorhynchus gorbuscha) within a diverse, large Barents Sea catchment

Journal of Fish Biology, EarlyView.
Abstract Pink salmon originate from the North Pacific area but were introduced into northwest Russia from the late 1950s onwards. Since 2017, the alien species has increased dramatically in abundance and rapidly invaded adjacent areas of the North Atlantic region.

Target discrimination in bubbly water

, 2012
A man-made sonar that can operate in bubbly water is relevant: decades of active sonar experience built up for deep water applications are insufficient for shallow water operations required of a changed maritime security landscape.

How man-made interference might cause gas bubble emboli in deep diving whales

, 2014
Recent cetacean mass strandings in close temporal and spatial association with sonar activity has raised the concern that anthropogenic sound may harm breath-hold diving marine mammals.

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
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 ...

Sonar-Based Simultaneous Localization and Mapping Using the Semi-Direct Method

Journal of Marine Science and Engineering
The SLAM problem is a common challenge faced by ROVs working underwater, with the key issue being the accurate estimation of pose. In this work, we make full use of the positional information of point clouds and the surrounding pixel data.
