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

ABSTRACT Understanding how populations are structured and adapt to their local environment is critical for developing effective management strategies. We used the commercially and culturally valued marine teleost Chrysophrys auratus (the Australasian snapper) as an exemplar of a high‐gene‐flow species to study genetic structure, population connectivity,

Global annual catch of tuna,tuna-like and shark species (1918-01-01 - 2019-12-31) (FIRMS level 0)
This dataset lists the global catch (in metric tons,t) of tuna and tuna-like species from 1918-01-01 to 2019-12-31. This dataset was computed using public domain,annual nominal catch datasets (also called total catch) released by the five tuna Regional ...

Genetic Bottleneck and Panmixia Following the Collapse of a Great Lakes Lake Whitefish Fishery
ABSTRACT Lake whitefish Coregonus clupeaformis abundance has declined throughout most of the Laurentian Great Lakes in North America for two decades. Current management strategies in Lake Erie assume that there is a single stock of lake whitefish that spawns in the West Basin.

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

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

ABSTRACT Climate change poses an unprecedented risk to fisheries ecosystems and economies globally. Ocean warming has led to observed geographic shifts and changes in the productivity of fish stocks. Due to the rapid pace of change in many of the world's oceans, there is a critical need to develop and apply scientific knowledge and tools that can help ...

The Atlantic Bluefin Tuna: A global perspective [PDF]
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

Updated summary of conditioned operating models for Atlantic bluefin tuna.
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 ...

ABSTRACT Ocean acidification (OA) remains a major and underexplored threat to marine fishes, particularly regarding reproductive physiology and early life stages (ELS). Although research over the past 15 years has documented diverse OA effects, substantial knowledge gaps persist.
