Potential feeding and spawning habitats of Atlantic bluefin tuna in the Mediterranean Sea

The fate of Atlantic bluefin tuna.

Tagging of the Northern Bluefin Tuna (thunnus Thynnus) in the East Atlantic and Mediterranean Sea in 2005

This paper represents a review of different tagging activities carried out on bluefin tuna (Thunnus thynnus) in the eastern Atlantic and Mediterranean Sea. Except in Croatia where tagging has been done on captive specimens, all other tagging campaigns, performed within framework of joint European Tuna Tagging Programme, have been done on bluefin tuna released in the open sea. Besides the taggin...

Environmental noise in spawning areas: the case of Atlantic Bluefin Tuna (Thunnus thynnus)

We here present an exploratory analysis aiming to seek whether the colour of environmental noise theory could help in understanding the intriguing reproductive strategy of Atlantic bluefin tuna (BFT). A frequency-based approach based on spectral exponents, f with <0, is chosen and applied on 10 biogeographical provinces covering the North Atlantic. The major BFT spawning area, i.e. the Mediter...

Co-Occurrence and Habitat Use of Fin Whales, Striped Dolphins and Atlantic Bluefin Tuna in the Northwestern Mediterranean Sea

Different dolphin and tuna species have frequently been reported to aggregate in areas of high frontal activity, sometimes developing close multi-species associations to increase feeding success. Aerial surveys are a common tool to monitor the density and abundance of marine mammals, and have recently become a focus in the search for methods to provide fisheries-independent abundance indicators...

Comparative Assessment of the Reproductive Status of Female Atlantic Bluefin Tuna from the Gulf of Mexico and the Mediterranean Sea

Despite attention focused on the population status and rebuilding trajectory of Atlantic bluefin tuna (Thunnus thynnus), the reproduction and spawning biology remains poorly understood, especially in the NW Atlantic. At present, the eastern and western spawning populations are believed to exhibit different reproductive characteristics and, consequently, stock productivity. However, our study su...
