The effects of playbacks of anthropogenic noise on the anti‐predator behaviour of Pacific sand lance, Ammodytes personatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Noise from human activities has increased and been shown to negatively impact marine animals. Marine mammals and fish are vulnerable to anthropogenic noise because they rely on sound to communicate, find food, avoid predators and sense their environment. Forage fish are small schooling pelagic fish, important to many predators and instrumental

The habitat use of ariid catfishes in coral reefs in northeastern Brazil

open access: yesJournal of Fish Biology, EarlyView.
Abstract Ariidae species occur across a wide range of habitats from freshwater to fully marine environments and are typically associated with soft‐bottom substrates. However, they are sometimes associated with hard‐bottom substrates such as coral reefs, but such association is poorly documented.

Impact of light pollution on fishes: Mechanisms and ecological consequences

open access: yesJournal of Fish Biology, EarlyView.
Abstract The increasing prevalence of artificial light at night (ALAN) is of growing ecological concern. By altering natural light regimes, ALAN affects the behaviour, physiology and life‐history of organisms. While research has largely focused on terrestrial ecosystems, aquatic ecosystems are increasingly exposed.

Winter feeding during the spawning migration of capelin north of Iceland

open access: yesJournal of Fish Biology, EarlyView.
Abstract Winter feeding during the spawning migration of capelin is often assumed to be minimal, because energy is allocated to reproduction. However, January–February surveys north of Iceland in 2018 and 2019 showed that prey occurred in 64% and 62% of 423 stomachs examined, respectively. Copepods (Calanus spp.) and euphausiids dominated the diet, and

Modulation of fatty acid profiles and turnover dynamics in jellyfish polyps through copepod diets: Insights into trophic interactions and nutrient flux

open access: yesEcology and Evolution
Fatty acids (FAs) are vital biomolecules crucial for determining food quality for higher trophic levels. To investigate FA transfer and turnover time in predators, we conducted a diet switch experiment using jellyfish polyps.

Introduction to trophology of walleye pollock

open access: yesИзвестия ТИНРО, 2015
Various aspects of walleye pollock feeding at different stages of its ontogenesis are reviewed and discussed. Structure and functional features of its mouth organs are considered with meristic and quantitative description of the filter one.

Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change

open access: yesJournal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.

The First Report of Cod Gill Poxvirus in Gills of Atlantic Cod (Gadus morhua L.) Suffering From Cardiorespiratory Disease

open access: yesJournal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Atlantic cod farming experiences renewed growth in Norway, and increased awareness is essential to address emerging diseases in this species. There are few reports on gill diseases in cod, and to date, no viral gill infections of cod have been documented. In this study, we collected samples from three sequential time points in summer 2023 from

Ontogenetic Development of Hyperostosis in the Crevalle Jack Caranx hippos (Linnaeus, 1766) and New Records of Affected Bone Regions

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Hyperostosis is a non‐pathological condition widely reported in marine teleosts, yet its developmental dynamics and underlying drivers remain poorly understood. This study investigates the ontogenetic progression and anatomical distribution of hyperostosis in Caranx hippos based on a growth series of 39 specimens collected along the Brazilian ...
