Biochemical Changes Occurring in Yellowfin Tuna Eggs during Embryonic Development
نویسندگان
چکیده
Changes in nutritional constituents and enzyme activities were clarified yellowfin tuna (YFT, Thunnus albacares) eggs during embryonic development, from immediately after fertilization to hatching. The protein levels the gradually increased with development until completion of In contrast, triglyceride (TG) free amino acid (FAA) declined hatching was complete, although energy composition FAAs lower than that TGs throughout development. These results indicate endogenous are preferentially expended as an source Overall, changes aspartate aminotransferase, alanine creatine kinase, alkaline phosphatase showed similar patterns First, diminished; then, they remained at constant, low just before hatching, when rapidly increased. This rapid increase consistent content, suggesting organ differentiation functionalization promoted this period. will contribute establishment mass-seeding production YFT.

Increase in mercury in Pacific yellowfin tuna.
Mercury is a toxic trace metal that can accumulate to levels that threaten human and environmental health. Models and empirical data suggest that humans are responsible for a great deal of the mercury actively cycling in the environment at present. Thus, one might predict that the concentration of mercury in fish should have increased dramatically since the Industrial Revolution. Evidence in su...

is too fast to be measured by the methods used. The second step, which involves the acylation of the enzyme and the concomitant liberation of pnitrophenol, is characterized by the rate constant k2= 3-15 sec.-'. The third step involves the liberation of acetate and reactivation of the enzyme; the rate of this reaction is defined by kI3= 0-0254 sec.-'. 2. The rate constant k2 for the second step ...
متن کاملNursery origin of yellowfin tuna in the Hawaiian Islands
Stable isotopes of carbon (δ13C) and oxygen (δ18O) in otolith cores (first 2 mo of age) of young-of-the-year (YOY) yellowfin tuna Thunnus albacares were used as natural tracers to predict the nursery origin of sub-adults (age-1) collected from the Hawaiian Islands. YOY fish were first collected from nurseries throughout the western and central Pacific Ocean (WCPO) to determine whether δ13C and ...
متن کاملDeep diving behavior observed in yellowfin tuna (Thunnus albacares)
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 first time that this species is indeed capabl...
متن کاملGeographic Differences in Persistent Organic Pollutant Levels of Yellowfin Tuna
BACKGROUND Fish are a source of persistent organic pollutants (POPs) in the human diet. Although species, trophic level, and means of production are typically considered in predicting fish pollutant load, and thus recommendations of consumption, capture location is usually not accounted for. OBJECTIVES Yellowfin tuna (Thunnus albacares) are harvested from across the world's oceans and are wid...
