Acoustic telemetry reveals high site fidelity of yellow‐phase American eels Anguilla rostrata in a large river

Journal of Fish Biology, EarlyView.
Abstract Movement patterns and habitat use of yellow‐phase American eels Anguilla rostrata in the Wolastoq/Saint John River were examined using acoustic telemetry. Tracking 72 tagged yellow‐phase eels from late summer 2021 to autumn 2023 revealed overall restricted longitudinal movements (mean linear range ± standard deviation [SD] 6.4 ± 10.9 km) and ...

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea

Journal of Fish Biology, EarlyView.
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

The theory of island biogeography and the stability of oceanic reef fish communities

Journal of Fish Biology, EarlyView.
Abstract Reef fish assemblages on oceanic islands offer valuable insights into ecological and evolutionary processes, yet their temporal dynamics remain poorly understood. This study evaluates the theory of island biogeography (TIB) with long‐term ecological monitoring to assess how island area, isolation from nearest reef and distance from mainland ...

The emergence of pathogens on fish in an impacted estuary and the role of non‐native piranhas in a potential bacterial infectious outbreak

Journal of Fish Biology, EarlyView.
Abstract As many tropical aquatic ecosystems worldwide, the Doce River estuary (DRE, southeastern Brazil) has increasingly faced multiple anthropogenic threats, including deforestation, mining, species introduction and water management. The 2015 collapse of the Fundão iron ore tailings dam severely changed water properties and increased heavy metal ...

Low-Income Fish Consumers’ Subsidies to the Fish Reduction Industry: The Case of Forage Fish

World
Forage fish, a crucial source of nutrition in developing countries, are, unfortunately, primarily used for fishmeal and aquafeed production for aquaculture, which mainly serves consumers in developed countries. Industrial fish use leaves a meager portion

Constructing Eco‐Responsible National Identities Through Collective Memory: Settler and Māori Histories of Environmental Change in Aotearoa New Zealand

Nations and Nationalism, EarlyView.
ABSTRACT A growing body of scholarship argues that collective memories of historical environmental change—formed and transmitted through museums, movies, novels, activist performances and other cultural texts and practices—can help nurture proenvironmentalism.
