Postprandial metabolism of Pacific bluefin tuna (Thunnus orientalis).
Specific dynamic action (SDA) is defined as the energy expended during ingestion, digestion, absorption and assimilation of a meal. This study presents the first data on the SDA response of individual tunas of any species. Juvenile Pacific bluefin tunas (Thunnus orientalis; body mass 9.7-11.0 kg; N=7) were individually fed known quantities of food consisting primarily of squid and sardine (meal...
متن کاملAn Examination of Sustainable Management of Pacific Bluefin Tuna Stock
This paper addresses a fundamental question in conservation ecology, which is the balance between rebuilding of a species’ population and exploiting them, by examining an appropriate sustainable management regulation for Pacific Bluefin tuna. The population of Pacific Bluefin tuna has been heavily depleted to just 2.6% of its historic unfished size by many years of overfishing. In order to rebu...
متن کاملAmino Acid Isotope Incorporation and Enrichment Factors in Pacific Bluefin Tuna, Thunnus orientalis
Compound specific isotopic analysis (CSIA) of amino acids has received increasing attention in ecological studies in recent years due to its ability to evaluate trophic positions and elucidate baseline nutrient sources. However, the incorporation rates of individual amino acids into protein and specific trophic discrimination factors (TDFs) are largely unknown, limiting the application of CSIA ...

متن کاملInfluence of swimming speed on metabolic rates of juvenile pacific bluefin tuna and yellowfin tuna.
Bluefin tuna are endothermic and have higher temperatures, heart rates, and cardiac outputs than tropical tuna. We hypothesized that the increased cardiovascular capacity to deliver oxygen in bluefin may be associated with the evolution of higher metabolic rates. This study measured the oxygen consumption of juvenile Pacific bluefin Thunnus orientalis and yellowfin tuna Thunnus albacares swimmi...
