Assessing the effect of temperate MPAs on elasmobranch communities [PDF]

open access: yes, 2023
Global chondrichthyan (sharks, skates, rays and chimaeras) populations are experiencing alarming declines, driven by intense targeted and incidental extraction.

Specific setup and methodology for computer-assisted sperm analysis (CASA) in evaluating elasmobranch sperm

open access: yesTheriogenology Wild
1. One-third of elasmobranch species are threatened with extinction, and the precise assessment of their sperm parameters and quality is one stage in the development of reproductive technology for animal conservation. 2. Computer-Assisted Sperm Analysis (

Metacestodes of Elasmobranch Tapeworms in Octopus vulgaris (Mollusca, Cephalopoda) from Central Mediterranean—SEM and Molecular Data

open access: yesAnimals, 2020
Cephalopods are intermediate/paratenic hosts in the life cycle of elasmobranch tapeworms, nevertheless most records of infection in this group of mollusks are outdated and fragmentary. The present work aimed to investigate the cestode fauna of the common

To release or not to release? Understanding sawfish release behavior in a global south complex fishery

open access: yesConservation Science and Practice, EarlyView.
This demonstrates the gap between existing top‐down laws and strategies (Current Approach) and the barriers fishers face while proposing an alternative pathway (Proposed Approach) based on collaboration, capacity building, and addressing socio‐economic factors.

Stable Isotope Analyses of Yellowfin and Blackfin Tuna Eye Lenses Reveal Life History Patterns

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Spatial geography, ontogenetic movement, and trophic patterns of mobile species are key elements of species life history, and knowledge of them is critical for effective marine resource management. For yellowfin tuna (Thunnus albacares; YFT) and blackfin tuna (Thunnus atlanticus; BLFT), residency durations and ontogenetic movements in the Gulf

Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Shark preferences: Only subtle effects of electromagnetic field exposure and substrate type on small‐spotted catshark (Scyliorhinus canicula) behaviour

open access: yesJournal of Fish Biology, EarlyView.
Abstract Offshore wind energy plays a crucial role in the transition to low‐carbon power generation. The expansion of offshore wind farms (OWFs) introduces anthropogenic electromagnetic fields (EMFs) from subsea power cables. Elasmobranchs, including sharks and rays, are sensitive to natural electric and magnetic fields used for navigation and prey ...

The oldest shark face—anatomy of the Devonian elasmobranch Phoebodus

open access: yesActa Palaeontologica Polonica
Phoebodus was recognized as the earliest elasmobranch known from articulated remains, a group which constitutes most modern cartilaginous fish comprising sharks, skates and rays. Its elongate body, the presence of two dorsal fins with fin spines, and the

Fishing profile and commercial landings of shark and batoids in a global elasmobranchs conservation hotspot [PDF]

open access: yesAnais da Academia Brasileira de Ciências
This paper describes the fishing profile and the temporal variation in the commercial landings of elasmobranchs in a global hotspot for their conservation and investigates the variables that influenced the landings. Census data on commercial catches were
