New Molecular Tools for the Identification of 2 Endangered Smooth-Hound Sharks, Mustelus mustelus and Mustelus punctulatus [PDF]

open access: yesJournal of Heredity, 2014
The smooth-hounds represent a significant proportion of the elasmobranch catch in the Adriatic basin of the Mediterranean Sea, where the common (Mustelus mustelus) and blackspotted (Mustelus punctulatus) smooth-hounds co-occur. The 2 species share several morphological and morphometric characters that lead to frequent misidentification.

Two thirds of species in a global shark fin trade hub are threatened with extinction: Conservation potential of international trade regulations for coastal sharks

open access: yesConservation Letters, Volume 15, Issue 5, September/October 2022., 2022
Abstract One third of chondrichthyan species (sharks, rays, and chimeras) are threatened with extinction, mainly due to unsustainable fishing. Large accessible international markets for meat and luxury products like dried fins can help drive overfishing by encouraging targeted capture or retention of high‐value export species.

Weight–length relations for 103 fish species from the southern Aegean Sea, Turkey [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2014
Using a traditional, commercial, crustacean bottom trawl net we collected fish samples from the southern Aegean Sea, from Dec 2009 to Nov 2010, at depths of 30–225 m.

First fossil record of Mustelus aff. punctulatus Risso, 1826: new evidence for a smooth-hound shark population in the Late Miocene North Sea Basin

open access: yesGeologica Belgica, 2022
Mustelus is a problematic genus in palaeoichthyology. Due to the scarcity of fossil teeth, relative homogeneity in tooth morphology and the lack of published extant dentitions, the early history of smooth-hound sharks remains poorly understood. Recently, two teeth were collected in the Tortonian Deurne Member (Diest Formation) near Antwerp (Belgium ...

Observations on the diet of the Starry skate, Raja asterias Delaroche, 1809 (Elasmobranchii: Rajidae) in the Adriatic Sea [PDF]

open access: yes, 2019
Diet of im­mature specimens of the Starry skate (Raja asterias) was investigated in three different parts of the northern Adriatic Sea. Decapod crabs were found to be the skate’s primary food source, followed by teleost fish and cephalopods.

Assessing the Stock Dynamics of Elasmobranchii off the Southern Coast of Sicily by Using Trawl Survey Data [PDF]

open access: yes, 2022
Elasmobranchii (sharks and rays), which have peculiar and vulnerable life-history traits, are highly threatened by fishing activities. Indeed, between 53% and 71% of Mediterranean elasmobranch species are at risk of extinction. In this context, using the

open access: yes, 2018
Hrskavičnjače (Chondrichtyes) su evolucijski stari razred koji se dijeli na dva podrazreda: prečnouste (Elasmobranchii) u koje spadaju morski psi (Selachii) i raže (Batoidea) te cjeloglavke (Holocephali).

Maximising MEDITS: using data collected from trawl surveys to characterise the benthic and demersal assemblages of the circalittoral and deeper waters around the Maltese Islands [PDF]

open access: yes, 2016
Data from MEDITS trawl surveys in the waters surrounding the Maltese Islands were analysed to characterise the benthic and demersal assemblages of the central Mediterranean, which are only poorly known, hampering Maltese authorities in meeting ...

DNA barcoding as a tool to explore elasmobranch diversity in environmental DNA off the Banc d´Arguin (Mauritania) [PDF]

open access: yes, 2021
Sharks and rays are the most threatened group of marine vertebrates. Extinction risk is highest for species in tropical and subtropical areas, often associated with developing nations that generally lack baseline data on species diversity.
