The relationship between the annual catch of bigeye tuna and climate factors and its prediction

open access: yesFrontiers in Marine Science
IntroductionIn order to explore the impact of climate factors on bigeye tuna catch, monthly data of nine climate factors, including El Niño-related indices (Niño1 + 2, Niño3, Niño4, and Niño3.4), Southern Oscillation Index (SOI), North Atlantic ...

Evaluating effectiveness of biological reference points for bigeye tuna (Thunnus obesus) and yellowfin tuna (Thunnus albacares) fisheries in the Indian Ocean

open access: yesAquaculture and Fisheries, 2017
Biological reference point (BRP) is one of the essential components in the management strategy evaluation that is used to determine the status of fishery stock and set management regulations. However, as BRPs can be derived from different models and many

Ecological Niche Changes of Two Sympatric Species (Pennahia argentata and Larimichthys polyactis) Revealed by Bulk and Compound Specific Isotope Analyses

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
We investigated trophic interactions between two sympatric fish species, Pennahia argentata and Larimichthys polyactis, using bulk and compound‐specific stable isotope analyses. CSIA of amino acids revealed similar trophic positions but distinct δ15N baselines, indicating ontogenetic niche shifts and offshore migration patterns.

Dynamic Interactions and Governance Capabilities of State and Non‐State Actors in Small‐Scale Tuna Fishery Certification in Indonesia

open access: yesEnvironmental Policy and Governance, Volume 35, Issue 6, Page 1012-1027, December 2025.
ABSTRACT Private sustainability fisheries certification has become increasingly popular over the past years as a new form of governance for fisheries in developing countries. The certification scheme is very promising because it offers benefits through market‐based incentives, including market access, social benefits by empowering fishers, and ...

Genetic evidence for inter-oceanic subdivision of bigeye tuna ( Thunnus obesus ) populations

open access: yesMarine Biology, 1998
Bigeye tuna (Thunnus obesus Lowe, 1839) are a commercially important species of tuna found in the Atlantic, Indian, and Pacific oceans. To initiate an analysis of bigeye tuna population-structure, three PCR–RFLP assays were developed based on the published mtDNA control-region sequences of four bigeye tuna.
