Trawling-Induced Sedimentary Dynamics in Submarine Canyons of the Gulf of Palermo (SW Mediterranean Sea)

Journal of Marine Science and Engineering
Bottom trawling in submarine canyons can affect their sedimentary dynamics, but studies addressing this topic are still scarce. In the Gulf of Palermo (NW Sicily, SW Mediterranean Sea), bottom trawling occurs on the continental slope, but principally ...

Improving selection in south eastern Australian whiting (Sillago spp.) trawls: effects of modifying the body, extension and codend

Scientia Marina, 2005
In response to a shift towards directed targeting of whiting, Sillago spp. by some penaeid trawlers in coastal waters off New South Wales, Australia, 3 experiments were done to examine the effects on the size and species selectivity of trawls associated ...

Assessing Loggerhead Turtle Exposure to Fisheries in Northwest Africa: Predicted Risk and Management Gaps. [PDF]

Ecol Evol
Biologging and Global Fishing Watch data reveal extensive spatial and vertical overlap between loggerhead turtles from the Cabo Verde population and fisheries across the Northeast Atlantic, highlighting areas of high predicted bycatch risk and gaps in current protections. ABSTRACT Bycatch is the accidental capture of non‐target animals in fishing gear,

Modeling Skin Mark Temporal Variations to Estimate the Sex of Delphinids with Low Sexual Dimorphism: Implications for Management and Conservation

Integrative Zoology, EarlyView.
This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation

Morphometric characteristics of Antarctic krill (Euphausia superba) and finfish bycatch in the krill fishery in the waters of South Orkney Islands during the 2022/23 fishing season

Frontiers in Marine Science
Determination of bar spacing of bycatch reduction devices (BRDs) should consider species composition and morphometric characteristics (particularly width) of target species krill and bycatch. This study conducted a scientific investigation of the finfish

Trawling disturbance on benthic ecosystems and consequences on commercial species: a northwestern Mediterranean case study

Scientia Marina, 2014
Trawling is known to disturb benthic communities and habitats, which may in turn indirectly affect populations of commercial species that live in close association with the seabed.

Impacts of Bottom Trawling and Litter on the Seabed in Norwegian Waters

Frontiers in Marine Science, 2018
Bottom trawling and seabed littering are two serious threats to seabed integrity. We present an overview of the distribution of seabed litter and bottom trawling in Norwegian waters (the Norwegian Sea and the southern Barents Sea).

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

Integrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Écrire au pouvoir pour participer au gouvernement des ressources. L’usage des mémoires dans la controverse sur le chalut (Normandie, premier XIXe siècle)

L'Atelier du CRH, 2015
The conflict about trawling, which started during the French Restauration between Chambers of Commerce from different fishing harbours in Normandy, is an ideal field to study both practical and legal uses of petitions.

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...
