Using Photographs in Fishers’ Ecological Knowledge Research: A Review and Field Study on Small‐Scale Fishers’ Knowledge of Coastal Habitats in the Central Mediterranean Sea

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Fishers interact daily with coastal environments, which generate a deep understanding of habitat characteristics, species associations and ecological change. Fishers’ ecological knowledge (FEK) is therefore a critical source of insight for marine science, offering observations that uniquely complement scientific data and, when incorporated ...

Landmark‐Based Morphometric Comparison of Juvenile Heteropneustes fossilis Reared in Pond and Recirculatory Aquaculture System

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Monitoring fish juvenile growth parameters is crucial for optimising aquaculture practices, ensuring high survival rates and improving overall productivity. For Heteropneustes fossilis (stinging catfish), a species of significant economic and nutritional value in Bangladesh, understanding larval growth dynamics is essential for hatchery ...

Preovulatory follicle growth dynamics indicates daily spawning synchronicity in wild-caught Atlantic horse mackerel off Portugal

Aquatic Living Resources, 2018
The Atlantic horse mackerel, Trachurus trachurus, is a commercially important species whose daily spawning dynamics are not yet fully understood. Existence of spawning synchronicity would facilitate application of the daily egg production method for ...

Assessment of Microplastic Ingestion in Commercial Marine Fish From Cities of Sibu and Kuching, Eastern Sarawak, Malaysia

Environmental Quality Management, Volume 36, Issue 2, August 2026.
ABSTRACT Microplastic (MP) pollution is an ever‐growing issue in the marine ecosystem around the world. However, the study on MP pollution in marine fish remains limited, particularly those conducted in Eastern Sarawak, Malaysia. Hence, this study investigated the occurrence of MP on the marine fish, collected from local fish market in the city of Sibu

Analysis of historical dark data shows multiple regime changes among pelagic migratory fishes around Japan over 120 years

Frontiers in Marine Science
An analysis of long-term (over-100-year) continuous catch data at local to regional scales (tens to hundreds of kilometres) is needed to deepen our understanding of the interaction between regime shifts of multiple fish species and marine environmental ...

A study on the mercury content in muscles in the fish family Carangidae from the fishing grounds off the coast of north-west Africa [PDF]

Acta Ichthyologica et Piscatoria, 1976
The mercury content in muscles was determined for 171 fishes belonging to three species of the family Carangidae. Significant differences in the content of this element were found between the species.

Contrasting Responses of Dissolved Oxygen in the Northern Benguela Upwelling System to Four Decades of Warming

Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The Northern Benguela Upwelling System (NBUS) is a highly productive yet low‐oxygen region, influenced by the combined effects of circulation and biogeochemical processes. Using data from a high‐resolution (∼7 km) coupled physical–biogeochemical model spanning 1980–2020, this study investigates long‐term dissolved oxygen (DO) variability in ...

Paralytic shellfish toxins in the Atlantic horse mackerel (Trachurus trachurus) over a bloom of Gymnodinium catenatum: the prevalence of decarbamoylsaxitoxin in the marine food web

Scientia Marina, 2013
This study reports the accumulation of paralytic shellfish toxins (PSTs) in Atlantic horse mackerel (Trachurus trachurus) over a bloom of the toxigenic dinoflagellate Gymnodinium catenatum. High levels of toxins, up to 4800 μg STXeq kg–1, were registered
