Ocean warming is already affecting global fisheries with an increasing dominance of catches of warmer water species at higher latitudes and lower catches of tropical and subtropical species in the tropics. Tuna distributions are highly conditioned by sea temperature, for this reason and their worldwide distribution, their populations may be a good indicator of the effect of climate change on gl...

Tobacco mosaic virus (TMV) is one of the devastating plant viruses in the world that infects more than 200 plant species. Movement protein plays a supportive role in the movement of other plant viruses, and viral coat protein is highly expressed in infected plants and affects replication and movements of TMV. In order to investigate genetic variation in the terminal fragment sequence in Iranian...

The main target species of Japanese purse seine operated in the tropical waters of the Pacific Ocean is skipjack tuna (Katsuwonus pelamis) and yellowfin tuna (Thunnus albacares) consisted of nearly 98 % to their total catch weight and the remaining is bigeye tuna (Thunnus obesus) according to logbook. The recent study of the vertical distribution of the three species around drifting FADs (fish ...

The Gulf of Maine, NW Atlantic Ocean, is a productive, seasonal foraging ground for Atlantic bluefin tuna (Thunnus thynnus), but commercial landings of adult size classes were up to 40% below the allocated total allowable catch between 2004 to 2008 for the rod and reel, harpoon, and purse seine categories in the Gulf of Maine. Reduction in Atlantic bluefin tuna catches in the Gulf of Maine coul...

El Nino Southern Oscillation (ENSO) is an important driver of interannual variations in climate and ecosystem productivity in tropical regions. However, detailed information about this important phenomenon of the Indian Ocean is scarce. Consequently, the objective of this study is to improve understanding of the impact of warm event El Nino and cool event La Nina on annual tuna landings from th...

With the increase in life expectancy, there is also growing interest in anti-aging treatments and technologies. The development of anti-aging functional drugs for the skin, and foods from natural sources, may offer solutions to this global matter. Aging involves structural, functional and biochemical changes that occur throughout cells and bodily tissues; the amount of hormones secreted from of...

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

Health of two farmed species of tuna was evaluated in farm surveys in Australia, Croatia and Spain. The results were discussed at tuna health workshop during EAFP 12th International Conference. While a wide range of parasites was found, few problems occurred during the surveys. The information obtained will be useful for future monitoring and research on health of farmed tuna. Introduction Fish...
