Physiological and behavioural thermoregulation in bigeye tuna (Thunnus obesus)
Nature, 1992Tuna are unique among teleost fishes in being thermoconserving. Vascular counter-current heat exchangers maintain body temperatures above ambient water temperature, thereby improving locomotor muscle efficiency, especially at burst speeds and when pursuing prey below the thermocline.

Physiological thermoregulation in bigeye tuna,Thunnus obesus
Environmental Biology of Fishes, 1994Although a growing body of evidence has indicated that tuna can thermoregulate and have body temperatures that are decoupled from immediate changes in ambient temperature, demonstrating the extent and time-course of body temperature changes in tuna moving through their natural environments has proved to be elusive.

Biogenic Amines Formation in Bigeye Tuna Steaks and Whole Skipjack Tuna
Journal of Food Science, 2002ABSTRACT: Putrescine, cadaverine and histamine formation was monitored in fresh and frozen/thawed Bigeye tuna steaks ( Thunnus obesus ) and whole Skipjack ( Katsuwonus pelamis ) stored at room temperature and in ice and to determine ...

Autoxidation of myoglobin from bigeye tuna fish (Thunnus obesus)
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1990Native oxymyoglobin (MbO2) was isolated directly from the skeletal muscle of bigeye tuna (Thunnus obesus) with complete separation from metmyoglobin (metMb) on a CM-cellulose column. It was examined for its stability properties over a wide range of pH values (pH 5-12) in 0.1 M buffer at 25 degrees C.

On the Blood Types of Yellowfin and Bigeye Tuna
The American Naturalist, 1962This work was undertaken to identify subpopulations of tunas by means of serological methods. Information concerning the blood types of albacore has been reported previously, (Suzuki, Shimizu and Morio, 1958; Suzuki, Morio and Mimoto, 1959). In these papers we reported two kinds of antigen, Tg1 and Tg2, and showed that albacore could be classified into

Monthly Bigeye Tuna Catches Forecasting Using Wavelet Functional Autoregression
2010 Third International Conference on Knowledge Discovery and Data Mining, 2010In this paper, the aim is to apply a functional autoregressive (FAR) model combined with multiscale wavelet analysis for monthly bigeye tuna catches forecasting in the ocean ecosystem of the equatorial Indian ocean. Wavelet technique performs a time-frequency analysis of a time series, which permits to decompose the raw time series into trend and ...

Wavelet Polynomial Autoregression for Monthly Bigeye Tuna Catches Forecasting
2009 Second International Conference on Environmental and Computer Science, 2009In this paper, multiscale wavelet analysis combined with a multivariate polynomial is presented to improve the accuracy and parsimony of 1-month ahead forecasting of monthly bigeye tuna catches in equatorial Indian Ocean. The proposed forecasting model is based on the decomposition the raw data set into trend and residuals components by using ...

Operational modelling of bigeye tuna ( Thunnus obesus ) spatial dynamics in the Indonesian region
Marine Pollution Bulletin, 2018With INDESO, Indonesia has implemented a system for the monitoring and management of its tuna resources. Despite increasing catch, very few is known about the dynamics and real abundance of tuna species in the Indonesian waters and adjacent oceanic regions.

Proceedings of the first world meeting on bigeye tuna
2021The annual catches of big eye are exceeded by those of only two other species of tuna, skipjack, Katsuwonus pelamis, and yellowfin, Thunnus albacares. However, because most of the bigeye caught are consumed fresh, whereas most of the skipjack and yellowfin caught are canned, the economic value of big eye exceeds that of any other species of tuna ...
