Evaluating Atlantic bluefin tuna harvest strategies that use conventional genetic tagging data

Frontiers in Marine Science, 2023
An individual tagging model was implemented within the spatial, seasonal, multi-stock, multi-fleet operating models of the peer-reviewed Management Strategy Evaluation (MSE) framework for Atlantic bluefin tuna to evaluate the benefits of a harvest ...

The Northern Atlantic Bluefin Tuna Fisheries: Management and Policy Implications [PDF]

SSRN Electronic Journal, 2004
In this paper, a discrete time, multi-gear and age structured bio-economic model is developed for the Northern Atlantic Bluefin Tuna, which is a paradigmatic example of the difficulties faced in managing highly migratory fish stocks. The 1995 U.N.

Pacific bluefin tuna (Thunnus orientalis) bycatch in the Atlantic Ocean

Journal of Fish Biology, EarlyView.
Abstract A large tuna was hooked by a Japanese longline fishery in the high seas near the Republic of Namibia. This fishing ground is mainly utilized for Thunnus albacares, Thunnus obesus and Thunnus alalunga by Japanese tuna longliners. Because the tuna was larger than the common size of these species, the specimen was sampled for genetic species ...

The Atlantic Bluefin Tuna: A global perspective [PDF]

, 2003
Cette communication présente un aperçu global de la biologie du thon rouge de l'Atlantique, de son exploitation et de sa gestion. La comparaison entre le thon rouge et toutes les autres espèces de thonidés montre que cette espèce se situe mondialement au premier rang parmi les autres thonidés pour un grand nombre de caractéristiques comme ressources et

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Review of Recent Studies on the Absolute and Relative Growth of Atlantic Bluefin Tuna: Similarities with the Pacific Bluefin Tuna [PDF]

Reviews in Fisheries Science & Aquaculture, 2018
[EN] This study aims to clarify some aspects of the growth of Atlantic bluefin tuna, Thunnus thynnus (L.), (ABFT) mainly regarding parameters of the growth equation and of relative growth, in this case length-weight relationships. There is a great volume of literature on these matters and there is a danger that the resulting confusion may give rise to ...

Listening to tuna: Acoustic characterization of captive juvenile yellowfin tuna (Thunnus albacares)

Journal of Fish Biology, EarlyView.
Abstract The effectiveness of passive acoustic monitoring (PAM) for studying marine biodiversity highly relies on comprehensive libraries of species‐specific sounds. While sound production is well‐documented in reef and freshwater fishes, the acoustic behaviour of ecologically and economically vital pelagic species like tunas still remains largely ...

Discovering where bluefin tuna, Thunnus thynnus, might go: using environmental and fishery data to map potential tuna habitat in the eastern Mediterranean Sea

Scientia Marina, 2012
Based on a dataset derived from commercial fisheries in the eastern Mediterranean Sea in 1998-2005, we applied generalized additive models (GAMs) to investigate the relative influence of a range of environmental factors on catch rates of Atlantic bluefin

Updated summary of conditioned operating models for Atlantic bluefin tuna.

, 2021
Bluefin tuna operating models were revised and refitted to data in order to: (1) account for a longer time period for which index data are available; (2) provide an improved interpretation of stock mixing data; (3) better represent assessment estimates of historical stock trends and (4) approximate uncertainties over the strength of past and future ...

Oxytetracycline as an otolith chemical marker in Atlantic bluefin tuna (Thunnus thynnus): Technical feasibility in culture

Journal of Fish Biology, EarlyView.
Abstract Reliable discrimination between wild and cultured fish is essential for traceability in aquaculture. This study reports the first successful application of intramuscular oxytetracycline (OTC) injection for otolith marking in juveniles of Atlantic bluefin tuna (Thunnus thynnus).
