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.

Intermediate filaments spatially organize intracellular nanostructures to produce the bright structural blue of ribbontail stingrays across ontogeny

Frontiers in Cell and Developmental Biology
In animals, pigments but also nanostructures determine skin coloration, and many shades are produced by combining both mechanisms. Recently, we discovered a new mechanism for blue coloration in the ribbontail stingray Taeniura lymma, a species with ...

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 ...

Occurrence of the hemoparasite Cyrilia spp. in the Amazonian stingray Potamotrygon wallacei [PDF]

Anais da Academia Brasileira de Ciências
Freshwater stingrays play a crucial ecological role in the Amazon; however, studies on their parasitic fauna still need to be made available. This study aimed to investigate the occurrence of hemoparasites, specifically Cyrilia spp., in specimens of ...

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Assessing Risk for Bycatch and Byproduct Species Using a Modified Sustainability Assessment for Fishing Effects (SAFE) Approach

Fish and Fisheries, Volume 27, Issue 4, Page 831-849, July 2026.
ABSTRACT Central to ecosystem‐based fisheries management is ensuring the sustainability of bycatch and byproduct species. However, the sustainability of these species is difficult to assess as the lack of information limits the use of traditional stock assessment methods.

Implications of Maternal Toxicant Effects on Size‐Dependent Fisheries' Management: A Meta‐Analysis

Fish and Fisheries, Volume 27, Issue 4, Page 895-911, July 2026.
Larger, older fish transfer higher mercury and PCB concentrations to their eggs, significantly reducing offspring hatching success, survival and growth rates in contaminated aquatic ecosystems. These findings suggest that the reproductive benefits of big old fat fecund female fish may be compromised by maternal toxicant transfer in polluted waters ...

Use of Pristis spp. (Elasmobranchii: Pristidae) by Hunter-Gatherers on the Coast of São Paulo, Brazil

Neotropical Ichthyology
Artifacts made from rays (rostral teeth and spine) are very common in shell mounds on the coast of São Paulo, Brazil. The presence of the genus Pristis among the studied species of elasmobranch fishes in this shell mounds reinforces the hypothesis these ...

Offspring Size Resolves a Population Growth Paradox in Rays and Skates

Fish and Fisheries, Volume 27, Issue 4, Page 927-941, July 2026.
ABSTRACT The maximum intrinsic population growth rate, rmax, is a key determinant of sustainable fishing limits and is increasingly used in risk assessments. We previously showed how the rmax of rays and skates (subclass Batoidea) scales with adult body size, temperature (and hence depth) such that smaller‐bodied species and those in warmer, shallower ...

High Diversity of Killer Whale Populations Revealed by Passive Acoustic Monitoring in Gwaii Haanas, Haida Gwaii, Northern British Columbia, Canada, With Insights Into Seasonal Occurrence

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Marine waters of Gwaii Haanas National Park Reserve, National Marine Conservation Area Reserve, and Haida Heritage Site (Gwaii Haanas) in southern Haida Gwaii, Canada, provide habitat for several killer whale (Orcinus orca) populations that are culturally important to the indigenous Haida Nation and listed under Canada's Species at Risk Act ...
