Age and growth of blackfin tuna (Thunnus atlanticus) caught under moored fish aggregating devices, around Martinique Island [PDF]

Aquatic Living Resources, 2004
Daily growth increments measured in the otolith of Thunnus atlanticus were used to estimate the age and growth of individuals, which were sampled from an artisanal fishery operating around fish aggregating devices (FADs) moored off Martinique Island. In this study, 76 otoliths were analysed for fish ranging from 20 to 68 cm fork lengths (FL).

Impact of mercury released from permafrost on food safety in Switzerland

Food Risk Assess Europe, Volume 2, Issue 4, October 2024.
ABSTRACT Climate change has caused the permafrost to thaw, releasing the previously sequestered mercury into the environment. Mercury has the ability to convert to methylmercury, a bioaccumulative neurotoxin. Exposure occurs in humans through the ingestion of contaminated food and it is associated with adverse health effects.

Twenty‐three years of PCR‐based seafood authentication assay development: What have we learned?

Comprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 4, July 2024.
Abstract Seafood is a prime target for fraudulent activities due to the complexity of its supply chain, high demand, and difficult discrimination among species once morphological characteristics are removed. Instances of seafood fraud are expected to increase due to growing demand.

Age, growth, and mortality of Blackfin Tuna in the Gulf of Mexico

Marine and Coastal Fisheries, Volume 16, Issue 3, June 2024.
Abstract Objective An otolith‐based aging approach was used to evaluate age and growth relationships, sexual dimorphism in growth, and derive mortality estimates for Blackfin Tuna Thunnus atlanticus in the Gulf of Mexico (GOM). Methods Blackfin Tuna (n = 395) were sampled from recreational fisheries and aged from 0 to 13 years, representing an increase

Location of S‐nitrosylated cysteines in protein three‐dimensional structures

Proteins: Structure, Function, and Bioinformatics, Volume 92, Issue 4, Page 464-473, April 2024.
Abstract Although S‐nitrosylation of cysteines is a common protein posttranslational modification, little is known about its three‐dimensional structural features. This paper describes a systematic survey of the data available in the Protein Data Bank. Several interesting observations could be made.

Shifts in the size and distribution of marine trophy fishing world records

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 1, January 2024.
Abstract The extensive nature of recreational angling makes it difficult to explore trends in global catches. However, trophy fishing world records may provide an insight into recreational fishing pressure on the largest species and size classes. Trophy fishing is promoted and recorded by the International Game Fish Association (IGFA), who manage an 80‐
