Shark‐dust: Application of high‐throughput DNA sequencing of processing residues for trade monitoring of threatened sharks and rays

Conservation Letters, 2023
Illegal fishing, unregulated bycatch, and market demand for certain products (e.g., fins) are largely responsible for the rapid global decline of shark and ray populations. Controlling trade of endangered species remains difficult due to product variety,

Listening to tuna: Acoustic characterization of captive juvenile yellowfin tuna (Thunnus albacares)

Journal of Fish Biology, EarlyView.
Abstract The effectiveness of passive acoustic monitoring (PAM) for studying marine biodiversity highly relies on comprehensive libraries of species‐specific sounds. While sound production is well‐documented in reef and freshwater fishes, the acoustic behaviour of ecologically and economically vital pelagic species like tunas still remains largely ...

Elasmobranchs small-scale fishery in Guatemala: Socioeconomic aspects and value chain structure

Social Sciences and Humanities Open
Small-scale fishing (SSF) stands as a cornerstone of economic activity along Guatemala's coastlines. Fisheries products, including those derived from elasmobranchs, serve as vital sources of income for fishers and dealers.

Tooth morphology of deep‐water catsharks of the genus Apristurus (Chondrichthyes: Pentanchidae) in the North Atlantic Ocean

Journal of Fish Biology, EarlyView.
Abstract The deep‐water catshark family (Pentanchidae) is the most species‐rich family among extant shark lineages. Within this family, the genus Apristurus is the largest, comprising small, deep‐sea species characterised by elongated bodies and dorso‐ventrally compressed snouts. Five Apristurus species are currently recognised from the North Atlantic,

Quantifying post‐release behaviour of a critically endangered elasmobranch over two capture events using high‐resolution archival tag data

Journal of Fish Biology, EarlyView.
Abstract During catch‐and‐release angling, highly resident species are susceptible to multiple recapture events. Biologging offers the opportunity to study post‐release behaviour in detail; however, most studies have focused on a single capture‐release event.

Comparative transcriptomics of elasmobranchs and teleosts highlight important processes in adaptive immunity and regional endothermy

BMC Genomics, 2017
Comparative genomic and/or transcriptomic analyses involving elasmobranchs remain limited, with genome level comparisons of the elasmobranch immune system to that of higher vertebrates, non-existent.

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

Journal 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 ...

Anchoring from shipping as a disturbance agent to temperate rocky reef fish: marked shifts observed in trophic and taxonomic guilds

Frontiers in Conservation Science
Anchoring impacts to marine environments from large, ocean-going ships is increasingly recognized as a global threat to marine biota. To date, no replicated assessment examining anchor disturbance to fish assemblages exists at the scale of ocean-going ...

Insights into diet and niche separation in the context of prey availability between two sympatric whiprays in a tropical intertidal estuary

Journal of Fish Biology, EarlyView.
Abstract Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary‐associated species in Australia, we cannot reliably assess the functional importance of these areas

A Review of Nonsteroidal Anti‐Inflammatory Drugs for Food‐Producing Animals With a Focus on Potential Applications for Farmed Finfish

Journal of Fish Diseases, EarlyView.
ABSTRACT In finfish aquaculture, there are several inflammatory diseases impacting productivity and animal welfare, however there are limited options available to veterinarians to treat inflammation and pain in fish. Nonsteroidal anti‐inflammatory drugs (NSAIDs) are widely used in terrestrial animals raised for human consumption to treat a range of ...
