Recent studies showed that regional abundance of loggerhead and leatherback turtles could oscillate interannually according to oceanographic and climatic conditions. The Western Mediterranean is an important fishing area for the Spanish drifting longline fleet, which mainly targets swordfish, bluefin tuna, and albacore. Due to the spatial overlapping in fishing activity and turtle distribution,...

Two species of Didymozoidae, Didymosulcus palati (Yamaguti 1970) and Didymosulcus philobranchiarca (Yamaguti 1970) were reported for the first time in South America, Atlantic Ocean, parasitizing three different tuna species from the coast of Rio de Janeiro, Brazil: Thunnus atlanticus (Lesson), Thunnus albacares (Bonnaterre) and Thunnus obesus (Lowe). Pairs of D. philobranchiarca were found on g...

Behaviour of yellowfin (Thunnus albacares) and bigeye tuna (T. obesus)

Aquaculture is providing an ever-increasing proportion of fish in the human food basket prompting a search for new species to expand the range available to consumers. Large tunids/scombrids have long-since been a very valuable resource providing not only high quality protein, but also a rich source of the highly beneficial omega-3 (or n-3) long-chain polyunsaturated fatty acids including eicosa...
