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

Aquaculture, 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.

Interactions of Mucus Monosaccharides and the Epidermal Microbiome in Four Benthic Elasmobranchs

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Here we collected mucus and microbes from the skin of Elasmobranchs to identify interactions between mucus and the microbial community. We identified key microbial genes involved in the metabolism of mucus carbohydrates in Elasmobranchs. ABSTRACT Epidermal mucus is a complicated mixture of macromolecules which acts as the first line of defence for ...

Dwarf False Catshark Planonasus parini [PDF]

, 2017
The Dwarf False Catshark (Planonasus parini) is endemic to the Arabian Seas region, where it is known from only three specimens taken off Socotra Island, Yemen. It occurs at depths beyond any current fisheries (560-1,120 m). The only known specimens of

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

Physiological 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.

Mechanisms of endoderm formation in a cartilaginous fish reveal ancestral and homoplastic traits in jawed vertebrates

Biology Open, 2014
In order to gain insight into the impact of yolk increase on endoderm development, we have analyzed the mechanisms of endoderm formation in the catshark S. canicula, a species exhibiting telolecithal eggs and a distinct yolk sac.

Histochemical Study of Enzyme Activity in the Digestive Tract of the Small-Spotted Catshark (Scyliorhinus canicula) and the Smooth-Hound (Mustelus mustelus)

Fishes
The small-spotted catshark and the smooth-hound are cartilaginous, carnivorous fish with similar depth ranges in their habitats. These two species are among the most abundant elasmobranchs in the Adriatic Sea and are frequently caught by local fishermen ...

¿ES POSIBLE CRIAR TIBURONES?: EL CASO DE LA PINTARROJA COMUN, SCHROEDERICHTHYS CHILENSIS (CHONDRICHTHYES, SCYLIORHINIDAE) IS IT POSSIBLE TO BREED SHARKS IN CAPTIVITY?: THE CASE OF THE DOGFISH, SCHROEDERICHTHYS CHILENSIS (CHONDRICHTHYES, SCYLIORHINIDAE)

Gayana, 2005
La crianza de animales es un fenómeno asociado a los orígenes del hombre moderno. Sin embargo, la crianza de especies marinas está relacionada con la producción intensiva en cultivo con fines comerciales.
