Can Purse Seiners Target Yellowfin Tuna?

Land Economics, 1994
Both purse seine and longline fleets exploit yellowfin tuna in the western Pa- cific region. Management options available to achieve the optimal allocation of the yellowfin stock depend on whether purse seiners can con- trol the species mix of their catch by targeting their fishing effort.

Geomagnetic field detection by yellowfin tuna

OCEANS 82, 1982
Yellowfin tuna (Thunnus albacares) learned to discriminate between two Earth-strength magnetic fields. In addition, magnetite was localized within the ethmoid bone complex of the skull. The easily-conditioned response to magnetic field stimuli indicate that the tunas possess a geomagnetic sense, while the presence of magnetite suggests a mechanism for ...

Thermoregulation in Yellowfin Tuna, Thunnus albacares

Physiological Zoology, 1979
To determine their capacity for thermoregulation, yellowfin tuna, Thunnus albacares, were subjected to a series of 12-h periods at $T_{a}'s$ of 20, 25, and 30 C. Muscle temperature, measured with an ultrasonic transmitter attached to the fish, and swim speed were simultaneously monitored.

Genomic resources for the Yellowfin tuna Thunnus albacares

Molecular Biology Reports
The Yellowfin tuna (Thunnus albacares) is a large tuna exploited by major fisheries in tropical and subtropical waters of all oceans except the Mediterranean Sea. Genomic studies of population structure, adaptive variation or of the genetic basis of phenotypic traits are needed to inform fisheries management but are currently limited by the lack of a ...

Characterization of Quality Deterioration in Yellowfin Tuna

Journal of Food Science, 1987
ABSTRACT The spoilage pattern of thawed yellowfin tuna carcasses was examined. After five days storage at 10° and 18°C, bacterial counts were low (< 10 3 ) although visible softening of the flesh was apparent.

Separation of proteases from yellowfin tuna spleen by ultrafiltration

Bioresource Technology, 2006
Separation of protease, trypsin and chymotrypsin from yellowfin tuna spleen extract by ultrafiltration (UF) using regenerated cellulose membranes with molecular weight cut off (MWCO) 30 and 100 kDa was studied. The 100 kDa membrane had a higher transmission of enzymes than that of the 30 kDa membrane.
