Food Safety Evaluation of Potential Human Exposure to Toxic Metals in Tuna Species

Journal of Xenobiotics
Fish has secured its spot as an important source of human nutrition with its extraordinarily rich nutritional contents; however, it also has the ability to bioaccumulate different potentially toxic elements.

Tuna Species Substitution in the Spanish Commercial Chain: A Knock-On Effect.

PLoS ONE, 2017
Intentional mislabelling of seafood is a widespread problem, particularly with high-value species like tuna. In this study we examine tuna mislabelling, deliberate species substitution, types of substitution and its impact on prices.

Relationship between weight and linear dimensions of Bluefin tuna (Thunnus thynnus) following fattening on western Mediterranean farms. [PDF]

PLoS ONE, 2018
This study presents various models based on formulae relating weight and dimensions (length, height and width) of Bluefin tuna, Thunnus thynnus (L.), fattened in captivity.

Inferring the Number of Spawning Events From Young‐of‐the‐Year Genomic Samples and Otolith‐Derived Birth Dates: A Richness‐Estimator Perspective

Fish and Fisheries, Volume 27, Issue 6, Page 1283-1289, November 2026.
ABSTRACT Estimating the number of spawning events per female is key to understanding reproductive output in batch‐spawning species, yet direct observation is often infeasible in the wild. Recent advances in genetic kinship inference enable the identification of maternal half siblings from young‐of‐the‐year genomic samples, while otolith‐based age ...

A Full Lifecycle Bioenergetic Model for Bluefin Tuna

PLoS ONE, 2011
We formulated a full lifecycle bioenergetic model for bluefin tuna relying on the principles of Dynamic Energy Budget theory. Traditional bioenergetic models in fish research deduce energy input and utilization from observed growth and reproduction. In contrast, our model predicts growth and reproduction from food availability and temperature in the ...

First attempt to assess the viability of bluefin tuna spawning events in offshore cages located in an a priori favourable larval habitat

Scientia Marina, 2013
Most of the Atlantic bluefin tuna caught by the purse-seine fleet in the Mediterranean Sea are transferred alive into transport cages and towed to coastal facilities where they are fattened.

Lack of Capacity: The Not‐So‐Hidden Factor Undermining Fisheries Governance

Fish and Fisheries, Volume 27, Issue 6, Page 1297-1306, November 2026.
ABSTRACT The demand for marine resources is increasing, and an increasing number of fish stocks are fully or overexploited. To turn this downward projection around, states need to strengthen the effectiveness, equity and implementation of fisheries management measures.

Spatial scale, means and gradients of hydrographic variables define pelagic seascapes of bluefin and bullet tuna spawning distribution. [PDF]

PLoS ONE, 2014
Seascape ecology is an emerging discipline focused on understanding how features of the marine habitat influence the spatial distribution of marine species.

Climate Vulnerability of Australian Seafood Systems: A National Assessment of Exposure and Adaptive Capacity

Fisheries Oceanography, Volume 35, Issue 6, Page 849-864, November 2026.
ABSTRACT Marine waters are becoming warmer and acidified and experiencing more intense and longer heatwaves under climate change. These changes are already impacting marine ecosystems and seafood production, which are vital for supporting food security and economic productivity.

Functional Adaptations for Load‐Bearing in a Dermal Bone: The Pectoral Fin Spine of the Russian Sturgeon (Huso Gueldenstaedtii)

Journal of Morphology, Volume 287, Issue 10, October 2026.
The pectoral fin spine (PFS) of the sturgeon is a robust dermal skeletal element that extends laterally and is located on the leading edge of the pectoral fin. The PFS is a load‐bearing dermal bone composed of peripheral parallel‐fibered bone and dermal osteonal bone organized around an interconnected neurovascular network.
