Recent physiological studies on the cardiovascular performance of tunas suggest that the elevated heart rates of these fish may rely on increased use of intracellular sarcoplasmic reticulum (SR) Ca2+ stores. In this study, we compare the cellular cardiac performance in endothermic tunas (bluefin, albacore, yellowfin) and their ectothermic sister taxa (mackerel) in response to acute temperature ...

The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is bound by its Article II, 3 to follow an ecosystem approach to management. This approach has been extended to the application of a precautionary approach in the late 1980s. In our review, we deal primarily with the science-related aspects of CCAMLR and its development towards an ecosystem approach to the managem...

The production of fish protein hydrolysate from underutilized species is attracting the industrial interest for increasing rich values. central composite design was used to optimize degree enzymatic hydrolysis freeze-dried (FPH) by application commercial Alcalase on recovery mixed small protein. effects time, temperature, pH and enzyme concentration (DH) five strains as Rastrelliger brachysoma ...

G-Actin was extracted from the acetone powder of the dark muscle of mackerel Pneumato phorus japonicus japonicus, and purified by a method which essentially consisted of polymerization in 0.1M KCl containing 0.1mm MgCl2, treatment with 0.6M KCI, and Sephadex G-200 gel filtration . Sedimentation constant (s020,w) of the dark muscle actin was 2.9S. The molecular weight was determined to be 42,000...

In the present study, we investigated the effect of collagen and collagen peptides from bluefin tuna abdominal skin on cancer cells. Collagens were extracted from bluefin tuna (Thunnus orientails) abdominal, mackerel, and carp skin. The calf and salmon collagen were used reagent grade as a standard samples. The main protein band pattern produced by SDS-PAGE of all collagen samples consisted of ...

In this paper, we propose a new method of the feature extraction for fish discrimination using mathematical morphology. The conventional research of fish discrimination used parameters which relied upon the physical characteristics of shape, contour and colour. But these methods were insufficient for pract,ical application system. Other physical pararneters include the colouring patterns, speck...
