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, EarlyView.
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 ...

Investigating Environmental DNA Variability and Species Detections Through Passive and Active Sampling Across Time: A Case Study From a Hyper‐Diverse Coastal System

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
This study compared the ability of active and passive eDNA filtration methods to capture environmental DNA in a marine environment with highly variable eDNA signals. Active sampling detected a greater proportion of fish biodiversity, whereas passive sampling detected a larger proportion of metazoa, with a trend of significant accumulation of numbers of

Proteomic Insights into Seminal Plasma and Spermatozoa Proteins of Small-Spotted Catsharks, Scyliorhinus canicula: Implications for Reproductive Conservation in Aquariums

open access: yesAnimals
In the ex situ conservation of chondrichthyan species, successful reproduction in aquaria is essential. However, these species often exhibit reduced reproductive success under human care.

New records of the lollipop catshark Cephalurus cephalus (Scyliorhinidae) from the Gulf of California, Mexico

open access: yesRevista Mexicana de Biodiversidad, 2012
On February 11th 2007, 13 neonates and 4 adults of Cephalurus cephalus were collected using a benthic sledge, during one oceanographic cruise (Talud X, St. 12) in the mid Gulf of California, Mexico (28º01’36” N, 111º51’50” W). The lollipop catsharks were

Barremian and Aptian (Cretaceous) sharks and rays from Speeton, Yorkshire, north-east England [PDF]

open access: yes, 2004
Bulk sampling of a number of horizons within the upper part of the Speeton Clay Type section has produced teeth and other remains of sharks and rays from several poorly studied horizons.

Effects of nasal parasite species in the small-spotted catshark Scyliorhinus canicula (Scyliorhinidae; Carcharhiniformes)

open access: yesFolia zoologica (Brno), 2020
. The presence of the parasitic copepod Neoalbionella globosa in the olfactory chamber of a specimen of the catshark Scyliorhinus canicula has been already reported in the literature, but this is the first record from the north-western Mediterranean Sea.

A new redescription of Galeus atlanticus (Vaillant, 1888) (Chondrichthyes: Scyliorhinidae) based on field marks [PDF]

open access: yes, 2006
The Atlantic sawtail catshark, Galeus atlanticus, has long been synonymous with the blackmouth catshark, Galeus melastomus, until the validity of G. atlanticus was resurrected by Muñoz-Chapuli and Ortega (1985).

Predictive habitat suitability models to aid conservation of elasmobranch diversity in the central Mediterranean Sea [PDF]

open access: yes, 2015
Commercial fisheries have dramatically impacted elasmobranch populations worldwide. With high capture and bycatch rates, the abundance of many species is rapidly declining and around a quarter of the world’s sharks and rays are threatened with extinction.

Contribution to the study of the morphology of the teeth of the nursehound Scyliorhinus stellaris (Chondrichthyes: Scyliorhinidae)

open access: yesScientia Marina, 2000
The first description of the dental formula and the number of teeth of Scyliorhinus stellaris are presented in this paper based on careful examination of teeth from 54 specimens (37 males and 17 females) collected in the eastern central Adriatic.
