Multi‐Seasonal eDNA Metabarcoding Highlights a Resurgence in Fish Diversity Across a Severely Impacted Estuarine Ecosystem

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Aquatic ecosystems have been in an alarming state of decline for decades. In particular, estuarine ecosystems have experienced long‐term declines in fish diversity due to factors such as habitat degradation, pollution and altered hydrology. Monitoring these systems is often limited by the difficulty and cost of conventional survey methods.

Air Exposure in Catshark (Scyliorhinus canicula) Modify Muscle Texture Properties: A Pilot Study

open access: yesFishes, 2018
Sharks are captured by tons for human consumption. Improving the quality of their meat will produce fillets that may have a higher economic value in the market, and thus be beneficial for the management of this fishery.

Genome‐wide identification and solute selectivity of aquaporins in the sharpnose sevengill shark, Heptranchias perlo

open access: yesPhysiological Reports, Volume 14, Issue 8, April 2026.
Abstract The aquaporin genes (aqps) are widely distributed among vertebrates. In cartilaginous fish, aqp3 and aqp10 are duplicated, whereas many species have lost aqp8. While the solute permeability of aquaglyceroporins and Aqp8 exhibits significant diversity, systematic evaluations of their activity within species are limited.

Inventory and comparison of abundance of parasitic copepods on fish hosts in the western Wadden Sea (North Sea) between 1968 and 2010 [PDF]

open access: yes, 2014
A conspicuous part of the parasite fauna of marine fish are ectoparasites, which attach mainly to the fins or gills. The abundant copepods have received much interest due to their negative effects on hosts.

Evolutionary history of the T cell receptor complex as revealed by small-spotted catshark ( Scyliorhinus canicula )

open access: yesDevelopmental & Comparative Immunology, 2017
In every jawed vertebrate species studied so far, the T cell receptor (TCR) complex is composed of two different TCR chains (α/β or γ/δ) and a number of CD3 subunits responsible for transmitting signals into the T cell. In this study, we characterised all of the TCR and CD3 genes of small-spotted catshark (Scyliorhinus canicula) and analysed their ...

Only One Percent of Important Shark and Ray Areas in the Western Indian Ocean Are Fully Protected From Fishing Pressure

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Delineation of Important Shark and Ray Areas (ISRAs) In the Western Indian Ocean was enhanced by the verification and incorporation of unpublished records. Even with this expanded dataset, ~99% of ISRA coverage fell outside of fully protected, no‐take MPAs.

Retinal histogenesis and cell differentiation in an elasmobranch species, the small‐spotted catshark Scyliorhinus canicula

open access: yesJournal of Anatomy, 2012
AbstractHere we present a detailed study of the major events in the retinal histogenesis in a slow‐developing elasmobranch species, the small‐spotted catshark, during embryonic, postnatal and adult stages using classical histological and immunohistological methods, providing a complete neurochemical characterization of retinal cells.
