Atlantic Bluefin Tuna (Thunnus thynnus) Biometrics and Condition. [PDF]

PLoS One, 2015
The compiled data for this study represents the first Atlantic and Mediterranean-wide effort to pool all available biometric data for Atlantic bluefin tuna (Thunnus thynnus) with the collaboration of many countries and scientific groups. Biometric relationships were based on an extensive sampling (over 140,000 fish sampled), covering most of the ...

Sexual maturity in western Atlantic bluefin tuna. [PDF]

Sci Rep, 2014
We introduce a novel endocrine approach for assessing the unresolved matter of the timing of sexual maturation in western Atlantic bluefin tuna (ABFT), a highly migratory population whose status remains uncertain. Ratios of follicle stimulating hormone to luteinizing hormone, a sexual maturity indicator, in all ABFT ≥ 134 cm curved fork length (CFL ...

Atlantic bluefin tuna: population dynamics, ecology, fisheries and management [PDF]

Fish and Fisheries, 2005
AbstractBoth old and new information on the biology and ecology of Atlantic bluefin tuna have confronted scientists with research challenges: research needs to be connected to current stock‐assessment and management issues. We review recent studies on habitat, migrations and population structure, stressing the importance of electronic tagging results ...

Estimating Natural Mortality of Atlantic Bluefin Tuna Using Acoustic Telemetry. [PDF]

Sci Rep, 2019
AbstractAtlantic bluefin tuna (Thunnus thynnus) are highly migratory fish with a contemporary range spanning the North Atlantic Ocean. Bluefin tuna populations have undergone severe decline and the status of the fish within each population remains uncertain.

Atlantic bluefin tuna spawn at suboptimal temperatures for their offspring. [PDF]

Proc Biol Sci, 2018
Life-history traits such as spawning migrations and timing of reproduction are adaptations to specific environmental constraints and seasonal cycles in many organisms' annual routines. In this study we analyse how offspring fitness constrains spawning phenology in a large migratory apex predator, the Atlantic bluefin tuna.

The Fate of Atlantic Bluefin Tuna [PDF]

Science, 2010
For several years, nongovernmental organizations (NGOs) have made Atlantic bluefin tuna (BFT) the archetype of overfishing and general mismanagement of the world fisheries. There are good reasons for this, as BFT crystallizes most of the problems of many fisheries: severe overcapacity, open access in international waters, high market value, and ...

First estimates of metabolic rate in Atlantic bluefin tuna larvae [PDF]

Journal of Fish Biology, 2020
AbstractAtlantic bluefin tuna is an iconic scombrid species with a high commercial and ecological value. Despite their importance, many physiological aspects, especially during the larval stages, are still unknown. Metabolic rates are one of the understudied aspects in scombrid larvae, likely due to challenges associated to larval handling before and ...

Reproduction of Atlantic bluefin tuna

Fish and Fisheries, 2020
AbstractThe reproductive success of fish populations depends on their reproductive potential and offspring survival to maturity. The reproductive potential affects recruitment and hence populations’ resilience and productivity. Extensive research carried out throughout the current century has improved our understanding of the reproductive biology of ...
