BACKGROUND Tuna species of the genus Thunnus, such as the bluefin tunas, are some of the most important and yet most endangered trade fish in the world. Identification of these species in traded forms, however, may be difficult depending on the presentation of the products, which may hamper conservation efforts on trade control. In this paper, we validated a genetic methodology that can fully d...

IDDRA Ltd Analysis of the impact on ACP countries of opening up the EU import market for canned tuna 1 Abstract In mid-2003 ACP canned tuna producers lost a degree of their comparative advantage over the larger Asian producers when the EU, abiding by a WTO ruling, assigned Thailand, the Philippines and Indonesia a 25,000 tonnes import quota of reduced tariff canned tuna. Protected by zero-rated...

The identification of biodiversity hotspots and their management for conservation have been hypothesized as effective ways to protect many species. There has been a significant effort to identify and map these areas at a global scale, but the coarse resolution of most datasets masks the small-scale patterns associated with coastal habitats or seamounts. Here we used tuna longline observer data ...

Background: The presence of heavy metals in the environment could constitute a hazard to food security and public health. These can be accumulated in aquatic animals such as fish. Canned fish is consumed regularly in many countries. In this study, the levels of heavy metals Cu, Ni, Fe and Cr were evaluated in commercial canned fish products that are commonly consumed in Iran. The canned fish ...

Archival and acoustic tagging were carried out in the exclusive economic zone (EEZ) of Papua New Guinea (PNG) in the western Pacific Ocean during 2006–07 to investigate the vertical behavior of tropical tuna found in association with large arrays of anchored FADs. Industrialized purse-seine fishing on anchored FADs has existed in the PNG EEZ for more than a decade. Archival tags were implanted ...
