Growth and age composition of northern bluefin tuna, Thunnus thynnus, caught in the Eastern Pacific Ocean, as estimated from length-frequency data, with comments on trans-Pacific migrations [PDF]

open access: yes, 1993
ENGLISH: The spawning of Pacific northern bluefin tuna, Thunnus thynnus, takes place only in the western Pacific Ocean (WPO), but substantial numbers of the juveniles migrate to the eastern Pacific Ocean (EPO), where they remain for several months, or ...

Larval Genomics as a Viable, Fisheries‐Independent Tool for Investigating Population Structure in Tropical Pacific Tunas

open access: yesMolecular Ecology, Volume 35, Issue 8, April 2026.
ABSTRACT Understanding how dispersal, life history, and environmental variability shape genetic connectivity in the open ocean remains a central challenge in evolutionary biology. Highly migratory marine predators like tunas have traditionally been considered genetically homogeneous across ocean basins, yet emerging genomic evidence suggests that ...

Culturable microbiota associated with farmed Atlantic bluefin tuna (Thunnus thynnus)

open access: yesAquatic Living Resources, 2017
This study examined culturable microbiota associated with farming of Atlantic bluefin tuna (Thunnus thynnus), an economically significant aquacultured fish species, in autumn and late spring. While sea water gave higher heterotroph plate counts than tuna

A representative sampling of tuna muscle for mercury control

open access: yesItalian Journal of Food Safety, 2020
The mechanisms of mercury accumulation and distribution in fish tissues are related to its high affinity for sulfhydryl groups in proteins. There is evidence that mercury is distributed unevenly based on the different reactivity of these groups in the ...

Spatial capture–recapture reveals resource use and declining skipper numbers in Baltic Sea salmon trolling fisheries

open access: yesEcosphere, Volume 17, Issue 3, March 2026.
Abstract Many populations of Atlantic salmon (Salmo salar) native to the Baltic Sea are endangered. A significant group targeting salmon in this region is the recreational trolling fishery. Due to frequent changes in fisheries regulations and conditions, both salmon conservation and fishers are affected.

Typology of the Albanian Small-Scale Fisheries

open access: yesCroatian Journal of Fisheries, 2022
The lack of reliable fisheries statistics hampers full assessment of the status of marine resources. Central to this problem are data-poor fisheries such as the Albanian seas and in particular the SSF sector.

Evaluating the Potential for Citizen Science Divers to Monitor Fish Biodiversity Through Passive eDNA Collection

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Passive capture of eDNA can be used as a tool for citizen scientist SCUBA divers to supplement visual surveys for marine species detection and is particularly useful for species that are rare or visually inaccessible to divers. ABSTRACT Environmental DNA (eDNA) marker gene sequencing, or metabarcoding, can be a powerful tool for monitoring marine ...

Multiresidue Analysis of Organic UV Filters and UV Stabilizers in Fish of Common Consumption

open access: yesFoods, 2020
Fish species can bioaccumulate different pollutants present in the marine environments and incorporate them into the trophic chain. In this work, the occurrence of organic ultraviolet (UV) stabilizers and filters in different species of fishes of high ...
