Can pingers mitigate the bycatch of the endangered Black Sea Harbour Porpoise? [PDF]
Incidental catch in fishing gear, mainly in bottom-set gillnets targeting turbot, is a major mortality factor for the Black Sea harbour porpoise (Phocoena phocoena relicta), an endangered endemic subspecies of cetacean.

The influence of cutting height on arthropods in farm grassland
Mowing at a cutting height of 13 cm slightly reduced the immediate negative impact of mowing compared to mowing at a height of 7 cm. Medium‐term effects overrode this benefit: the number of vegetation‐dwelling arthropods remained strongly reduced two and four weeks after mowing, regardless of the cutting height.

Test of light emitting diodes (LED) as a possible bycatch mitigation measure in a gillnet fishery
Substantial seabird bycatch occurs in North Atlantic lumpfish fisheries, potentially impacting seabird populations and raising concerns about the fisheries’ sustainability. Despite increased efforts to address this issue, existing approaches have yielded

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 Macrourid species constitute the main bycatch in Southern Ocean toothfish longline fisheries. We report the first confirmed record of Whitson's grenadier, Macrourus whitsoni, in the South Georgia toothfish fishery. Mitochondrial cox1 DNA barcoding confirmed its presence in bycatch samples collected around South Georgia and the northern South ...

Here, we evaluated the ecological value of bird detections obtained opportunistically from camera traps by comparing them with standardized point count surveys conducted in 2023–2024, across the metropolitan area of Firenze, central Italy, and explored their potential to indicate broader urban biodiversity patterns through cross‐taxa relationships with

Kogia Records in Brazilian Equatorial and Southwestern Atlantic Oceans
ABSTRACT The pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales are cryptic cetaceans characterized by inconspicuous surfacing behavior, small group sizes, and deep‐diving habits, making visual detection particularly challenging. Here, we present the first broad‐scale passive acoustic monitoring (PAM) assessment of Kogia spp.

A depth model for informing Chinook salmon bycatch risk in the Gulf of Alaska
Background Bycatch of Chinook salmon (Oncorhynchus tshawytscha) in the Gulf of Alaska walleye pollock (Gadus chalcogrammus) fishery poses both conservation and management challenges. While fleet communication and excluder devices have improved mitigation

ABSTRACT Climate change poses an unprecedented risk to fisheries ecosystems and economies globally. Ocean warming has led to observed geographic shifts and changes in the productivity of fish stocks. Due to the rapid pace of change in many of the world's oceans, there is a critical need to develop and apply scientific knowledge and tools that can help ...

Satellite‐Based Fishing Fleet Tracking: A New Foundation for Fisheries Science and Management
ABSTRACT Satellite‐based vessel‐tracking technologies have ushered in a new era for monitoring fishing activity at scale. By combining artificial intelligence (AI) methods with remotely‐sensed data, researchers can now detect, classify and analyse fishing behaviour across vast and previously unobservable ocean regions.
