Comparison and selection of protease and lipase sources from visceral organs of three tuna species [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2008
Tuna viscera accounts for 7-8% of body weight and its value is still underutilized. This paper investigated on the influence of three tuna species and their individual visceral organ on the activities of three enzymes in tuna viscera.

Variation in yellowfin tuna (Thunnus albacares) catches related to El Niño-Southern Oscillation events at the entrance to the Gulf of California [PDF]

, 2006
Fishery catch data on yellowfin tuna (Thunnus albacares) were examined to study the effects of El Niño events between 1990 and 1999 for an area in the northeastern tropical Pacific (18−24°N, 112−104°W).

Fleet Behaviour Under Economic Uncertainty: Multi‐Species Policy Scenarios for the Purse‐Seine Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT Managing fishing effort remains a central challenge in achieving sustainability in many fisheries, particularly where high‐value species attract intense competition. In the Indian Ocean tropical tuna fishery, understanding how fishers respond to changing bio‐economic conditions is essential for developing effective management.

Deep diving behavior observed in yellowfin tuna (Thunnus albacares) [PDF]

Aquatic Living Resources, 2006
Yellowfin tuna (Thunnus albacares) are known to preferentially occupy the surface mixed layer above the thermocline and it has been suggested that they are physiologically restricted to water temperatures no more than 8 ◦ C colder than surface waters. However, we here report for dive data acquired from a large yellowfin tuna which demonstrate for the ...

Microencapsulation of trypsin from the intestine of yellowfin tuna (Thunnus Albacares)

IOP Conference Series: Earth and Environmental Science, 2022
Abstract Fish viscera is one of the waste products from fisheries that have not been widely used it tends to be disposed of more. Whereas in fish innards there are some enzymes including the trypsin found in the intestines. To increase the added value of fish viscera, a study on the extraction and microencapsulation of trypsin from fish ...

Pacific bluefin tuna (Thunnus orientalis) bycatch in the Atlantic Ocean

Journal of Fish Biology, EarlyView.
Abstract A large tuna was hooked by a Japanese longline fishery in the high seas near the Republic of Namibia. This fishing ground is mainly utilized for Thunnus albacares, Thunnus obesus and Thunnus alalunga by Japanese tuna longliners. Because the tuna was larger than the common size of these species, the specimen was sampled for genetic species ...
