Recreational Fisheries in Türkiye: Socio‐Economic Profiles, Technological Trends and Governance Challenges

Fisheries Management and Ecology, Volume 33, Issue 5, Page 1057-1070, October 2026.
ABSTRACT Recreational fisheries in Türkiye constitute an understudied socio‐economic sector spanning marine and freshwater ecosystems across the Mediterranean and Black Sea basins, yet robust national participation estimates remain constrained by the absence of a comprehensive registry or probability‐based sampling frame.

Linking species distribution models with population abundance to support adaptive fisheries management

Ecography, Volume 2026, Issue 9, September 2026.
Understanding how environmental variability structures essential fish habitat (EFH) is central to managing keystone populations in dynamic marine ecosystems. Using nearly three decades of standardized survey data (1994–2021) from the Adriatic Sea, we present the first basin‐scale, process‐based framework linking estimated habitat suitability and ...

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 ...

Ocean sediments and shifting baselines—A call to revise European habitat classifications

Journal of Applied Ecology, Volume 63, Issue 9, September 2026.
Shifting baselines affect the appropriateness of existing habitat classification frameworks, potentially reducing MPA integrity and efficacy. To enable representative mapping, accurate sensitivity assessments and appropriate management of marine habitats, EUNIS classifications require more flexibility.

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.

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

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
