Fewer devil rays in the sea: Evidence of declining mobulid populations off India's coast
Manta and devil rays are declining globally due to targeted and incidental capture, but species‐specific assessments are limited by unmonitored fisheries. Using morphometric, demographic, and fishery metrics, we show for the first time in India long‐term (2013–2023) declines in Mobula mobular, Mobula tarapacana, Mobula birostris, and Mobula thurstoni ...

ABSTRACT Estuaries provide essential habitats for many fish species, but their confined and accessible nature may increase fish vulnerability to capture, and few empirical studies have quantified the value of restricting net fisheries in such areas.

ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

Prioritizing Shark, Ray, and Chimaera Conservation in Rapidly Changing Polar Waters
Polar sharks, rays, and chimaeras face growing pressures from changing sea‐ice conditions, expanding fisheries, and limited protection. Our assessment highlights where critical habitats occur and how Important Shark and Ray Areas (ISRAs) can support more targeted conservation and fisheries management across the Arctic and Antarctic.

A Process‐Based Theory of Fishing
ABSTRACT The processes that lead to the capture of marine organisms in fishing gear are inherently complex, arising from interactions between the deployment of fishing effort, gear efficiency, and species‐specific demography and behaviour. A mechanistic understanding of these processes provides a principled basis for developing management approaches ...

IntroductionFor 87 years, gillnets have been deployed off up to 51 beaches in New South Wales, Australia, to reduce bites on humans by white (Carcharodon carcharias), bull (Carcharhinus leucas), and tiger (Galeocerdo cuvier) sharks. Recently, to minimise

Discards monitoring in the gillnet fishery for sole
Approximately 2-3% of the Dutch fishing quota for sole (Solea solea) is caught by a 60-vessel strong inshore fleet of gillnetters. From their home ports in IJmuiden, Scheveningen and Den Helder, these vessels fish typically with bottom-set gillnets for sole during 1 day trips between March and October.
