Phenotypic diversity of infectious red sea bream iridovirus isolates from cultured fish in Japan.
Megalocytivirus is causing economically serious mass mortality by infecting fish in and around the Pacific region of Asia. The recent emergence of many new iridoviruses has drawn attention to the marked taxonomic variation within this virus family. Most studies of these viruses have not included extensive study of these emergent species. We explored the emergence of red sea bream iridovirus (RS...
متن کاملThe effects of dietary retinoic acid on body lipid deposition in juvenile red sea bream
A 6-week feeding trial was conducted to investigate the effects of dietary retinoids, especially retinoic acid, an anti-adipogenic factor in mammals, on lipid deposition in juvenile red sea bream Ž . Ž initial body weight: 8.5 g . The fish were fed either a commercial diet control: diet 1, crude . Ž . protein 61.7%, crude fat 13.9% , or diets supplemented with 100 mg retinyl acetate diet 2 , 10...
متن کاملDifferential effects on proliferation of GH and IGFs in sea bream (Sparus aurata) cultured myocytes.
Primary culture of gilthead sea bream skeletal muscle cells was used to examine the effects of growth hormone (GH) and insulin-like growth factors (IGFs) in fish muscle proliferation and growth. Proliferation was measured as the percentage of positive cells expressing the proliferating cell nuclear antigen (PCNA) analyzed by immunocytochemistry. First, the effects of GH from two different origi...
متن کاملCymothoid parasite Ceratothoa parallela inflicts great losses on cultured gilthead sea bream sparus aurata in Greece.
For the first time Ceratothoa parallela (Otto, 1828), a cymothoid isopod, is reported parasitizing cage-cultured gilthead sea bream Sparus aurata, in Greece. The specimens observed are larvae (Pullus secundus). They were found in the branchial and buccal cavity of young gilthead sea bream of 2 g mean body weight, upon introduction in the cages in an intensive cage farm facility. The species was...
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...
