Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

open access: yesFisheries Management and Ecology, Volume 33, Issue 3, Page 463-478, June 2026.
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, fine-scale spatial partitioning and sexual segregation in Rajidae, determined using passive acoustic telemetry

open access: yes, 2021
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 ...

Predicting Historical Populations and Evaluating Shifting Baselines of Traditionally Exploited Fisheries

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 506-518, May 2026.
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 ...

Reproductive Dynamics of the Blonde Ray (Raja brachyura) in Portuguese Waters: Timing, Maturity and Fecundity

open access: yesFishes
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

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
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

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
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 ...

Discard Survival of Thornback Ray (Raja clavata), Undulate Ray (Raja undulata) and Small‐Eyed Ray (Raja microocellata) in Northeast Atlantic Inshore Fisheries

open access: yesFisheries Management and Ecology, Volume 33, Issue 2, Page 355-367, April 2026.
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 ...
