Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Stranded cetaceans

open access: yesAnimal Welfare, 1994
The RSPCA (Royal Society for the Prevention of Cruelty to Animals) has produced a second edition of its stranded whales booklet. The first version was published out of the RSPCA's 1983 Stranded Whale Workshop and this 1994 edition incorporates additional information from a follow-up seminar run by the Society in November 1992.

DNA‐based identification of anadromous fishes (Alosa spp., Family Clupeidae) in stomach contents of marine groundfish

open access: yesJournal of Fish Biology, EarlyView.
Abstract Using DNA techniques for prey identification is an emerging approach for enhancing the precision and accuracy of trophic information. We evaluated the effectiveness of DNA‐based prey identification in conjunction with visual stomach content analysis of commercially important groundfish in the nearshore Gulf of Maine, with a focus on ...

Candida spp. in Cetaceans: Neglected Emerging Challenges in Marine Ecosystems

open access: yesMicroorganisms
Cetaceans, which are crucial in marine ecosystems, act as sentinels for ecosystem and human–environmental health. However, emerging fungal infections, particularly by Candida spp., pose a growing concern in these marine mammals.

Postcranial anatomy of the Miocene hippopotamoids of Toros‐Menalla, Chad

open access: yesJournal of Anatomy, EarlyView.
We establish a framework for the identification of postcranial remains in hippopotamoids by describing and comparing for the first time two late Miocene hippopotamoids from Toros‐Menalla, Chad (Hexaprotodon garyam, an early hippopotamid, and Libycosaurus bahri, the last African anthracothere) with the common hippopotamus.

Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

Establishing death in stranded Odontocetes (toothed whales) using other mammals : a pilot study : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Zoology at Massey University [PDF]

open access: yes, 2003
The aim of this study was to investigate and evaluate a new method for determining death in stranded odontocetes (toothed whales). The new method was using the pulsations seen in the retinal blood vessels in the place of the heart rate. The retinal blood

The Franciscana (Pontoporia blainvillei) in the Northern Limit of the FMA II: Strandings and Habitat Use in Ilha Grande Bay

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The presence of the franciscana (Pontoporia blainvillei) at the northern limit of the FMA II was investigated using a range of methods, including monitoring of strandings, boat surveys, and passive acoustic monitoring (PAM). Franciscana strandings were recorded within the distributional gap between Macaé (22°55′ S) and Ilha Grande (23°09′ S ...

Advancing Marine Bioacoustics With Deep Generative Models: A Hybrid Augmentation Strategy for Southern Resident Killer Whale Detection

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Automated detection and classification of marine mammal vocalizations is critical for conservation and management efforts but is hindered by limited annotated datasets and the acoustic complexity of real‐world marine environments. Data augmentation has proven to be an effective strategy to address this limitation by increasing dataset ...
