Abstract: Abstract The direct impacts of fishing on chondrichthyans (sharks, rays and chimeras) are well established. Here we review a largely unreported, often misinterpreted and poorly understood indirect impact of fishing on these animals — capture-induced… read more here.

DOI: 10.1016/j.marpol.2018.10.033
Abstract: Abstract Unmanaged fishing mortality is considered the biggest threat to sharks and rays, which are commonly discarded after being captured in commercial and recreational fisheries directed at more economically valuable fishery resources. Quantifying mortality prior… read more here.

DOI: 10.1016/j.ydbio.2020.07.014
Abstract: Sharks and rays (elasmobranchs) have the remarkable capacity to continuously regenerate their teeth. The polyphyodont system is considered the ancestral condition of the gnathostome dentition. Despite this shared regenerative ability, sharks and rays exhibit dramatic… read more here.

DOI: 10.1073/pnas.2216891120
Abstract: Overfishing is the most significant threat facing sharks and rays. Given the growth in consumption of seafood, combined with the compounding effects of habitat loss, climate change, and pollution, there is a need to identify… read more here.

DOI: 10.1111/jfb.14665
Abstract: In southern Brazil, we investigated shark and ray capture records in an integral protection marine protection area (MPA), that allows fishing in your area. We found 10 sharks and nine rays species, of which 88.5%… read more here.

DOI: 10.3390/genes12030324
Abstract: Chondrichthyes occupy a key position in the phylogeny of vertebrates. The complete sequence of the mitochondrial genome (mitogenome) of four species of sharks and five species of rays was obtained by whole genome sequencing (DNA-seq)… read more here.

DOI: 10.7717/peerj.15396
Abstract: Considerable research exists on the life history traits, evolutionary history, and environmental factors that shape the population genetic structure of marine organisms, including sharks and rays. Conservation concerns are particularly strong for this group as… read more here.
