Effectiveness of a vaccine against red sea bream iridoviral disease in a field trial test.
Since 1990, red sea bream iridovirus (RSIV) has caused high mortalities in the summertime in cultured red sea bream Pagrus major in southwest Japan. To establish control measures for red sea bream iridoviral disease (RSIVD), the effectiveness of a formalin-killed viral vaccine was evaluated in a field trial. Two groups each consisting of 1000 juvenile red sea bream were either intraperitoneally...
متن کاملKinetic analysis of a chitinase from red sea bream, Pagrus major.
Kinetic analysis was done on the 46-kDa chitinase (EC 3.2.1.14) purified from the stomach of red sea bream, Pagrus major, using glycolchitin and N-acetylchitooligosaccharides (GlcNAc(n), n=2-6) as substrates. High activity was observed at two pHs, such as 2.5 and 9.0, toward glycolchitin as seen in other insect chitinases, and also at both pH 2.5 and 5.0 even toward a short substrate, N-acetylc...
متن کاملExposure of eggs to solar UV-B leads to reduced hatching rates in two sparid fishes, red sea bream Pagrus major and black sea bream Acanthopagrus schlegeli.
Hatching success was examined under exposure to solar ultraviolet radiation (UVR) using filters to give three different light conditions [C1: UV-B, UV-A and photosynthetically active radiation (PAR), C2: UV-A and PAR, C3: PAR] in red Pagrus major and black Acanthopagrus schlegeli sea bream. Hatching rate of both species was reduced by an exposure over a 2 day period to UVR and was not significa...
متن کاملAbundant and constant expression of uncoupling protein 2 in the liver of red sea bream Pagrus major.
Four overlapping cDNA fragments encoding a partial sequence for uncoupling protein 2 (UCP2) were amplified by PCR using degenerate primers from the liver of a marine teleost fish, red sea bream (Pagrus major). The partial sequence was 674 bp long, encoding 224 amino acids. The deduced amino acid sequence from the cDNA partial sequence contained the signature motifs for mitochondrial transporter...
متن کاملDIETARY SUPPLEMENTATION OF LIPID AND INORGANIC PHOSPHORUS TO DEVELOP ENVIRONMENT-FRIENDLY FEED FOR YOUNG RED SEA BREAM, Pagrus major
An experiment was conducted to investigate the effects of dietary lipid and inorganic phosphorus supplementation on growth, retention and loading of phosphorus and nitrogen in young red sea bream. Two levels of lipid (190 and 250 g/kg) and two levels of phosphorus (14 and 19 g/kg) in the dry diets were tested. Four practical diets were formulated and coded as L0P0, L0P1, L1P0 and L1P1, respecti...
