ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Habitat selection is the process by which an individual makes an active decision to make use of a particular habitat when others are available. The ability to infer habitat selection therefore requires observations of movement through space and time ...

ABSTRACT Development of data‐intensive stock assessment and ecosystem‐based models has improved our understanding of shifting species abundance in response to fishing, ocean ecology, and species interactions. Along with this analytical progress is evidence that many stocks lack data required for complex models, resulting in data‐limited options for ...

Within the Rajidae family, the blonde ray (Raja brachyura) is considered one of the less resilient species to fishing pressure and other anthropogenic pressures, primarily due to its late maturity and large maximum size, which can exceed 120 cm total ...

Machine‐assisted image analysis facilitates conservation of iconic elasmobranchs
We present a case study involving a photo‐ID database of flapper skate (Dipturus intermedius) from Scotland, which was used to train a multistage, deep learning model, to enable automatic assessment of the similarity between flapper skate newly submitted to the database and those pre‐existing in the database.

The Unseen Crisis of Sharks and Rays in Senegal
This study presents a conservative quantitative assessment of shark and ray landings and trade in Senegal, revealing extensive exploitation of threatened species. Surveys at two major artisanal processing sites in the Casamance region recorded over 170,000 individuals, mostly rays, with nearly all biomass comprising species at risk of extinction, and ...

ABSTRACT Quantifying discard survival of species is crucial for effective fishery management. Electronic tags and visual health assessments were used to estimate postrelease survival of commercially caught thornback ray (Raja clavata), undulate ray (Raja undulata) and small‐eyed ray (Raja microocellata) from Northeast Atlantic inshore fisheries ...
