Physiological response to capture stress in endemic Southern African catsharks (family
Journal of Fish Biology, 2021 AbstractFishing is the major threat to marine fish populations, particularly to higher trophic‐level predators such as sharks. Many sharks, and other fish, are caught as commercial by‐catch or for recreational purposes and then released; therefore, it is important to understand the effects of capture stress on their physiology and subsequent survival ...

Frontiers in Marine Science, 2020 Fishers “local ecological knowledge” (LEK) can be used to reconstruct long-term trends of species that are at very low biomass due to overfishing. In this study, we used historical memories of Sicilian fishers to understand their perception of change in ...

New biogeographic data and DNA barcodes for the Indian swellshark, Cephaloscyllium silasi (Talwar, 1974) (Elasmobranchii: Carcharhiniformes: Scyliorhinidae), from Andaman waters [PDF]
Acta Ichthyologica et Piscatoria, 2016 Indian swellshark, Cephaloscyllium silasi (Talwar, 1974), is reported for the first time in Andaman waters, India which is a considerable extension of its known distribution range with more than 1000 km toward eastern Indian EEZ.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.ABSTRACT Elasmobranchs in the Mediterranean Sea face intense human‐induced pressures, with nearly half of their populations at risk of extinction. Overexploitation, limited data availability, lack of international cooperation and uneven public awareness hinder effective management.

Fisheries Management and Ecology, Volume 33, Issue 3, Page 463-478, June 2026.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 ...

Environmental 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

Complete mitochondrial genome and the phylogenetic position of the blackspotted catshark Halaelurus burgeri (Carcharhiniformes: Scyliorhinidae). [PDF]
Mitochondrial DNA B Resour, 2016 In this study, the mitogenome of the blackspotted catshark Halaelurus burgeri was first determined. This circle molecular was rich in A (30.7%)+T (30.4%), poor in C (25.0%)+G (13.8%) and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a longest control region (3481 bp with lots of repeated motifs) in sharks. Two start codons (ATG and
