Microstructure, mechanical, and biomimetic properties of fish scales from Pagrus major

Journal of Structural Biology, 2003
The fish scale of Pagrus major has an orthogonal plywood structure of stratified lamellae, 1-2 microm in thickness, consisting of closely packed 70- to 80-nm-diameter collagen fibers. X-ray diffraction, energy-dispersive X-ray analysis, and infrared spectroscopy indicate that the mineral phase in the scale is calcium-deficient hydroxyapatite containing

Differences between Pagrus major and Pagrus auratus through mainly mtDNA control region analysis

Fisheries Science, 2000
SUMMARY: The magnitude of intraspecific and interspecific genetic differentiation in Pagrus major collected from two Japanese areas, the East China Sea (ECS) and the South China Sea (SCS), and Pagrus auratus, collected from Australia (AUS) and New Zealand (NZ), was estimated using restriction fragment length polymorphism (RFLP) analysis and DNA ...

Iridovirus Infection of Cultured Red Sea Bream, Pagrus major.

Fish Pathology, 1992
1990年秋に初めて発生し, 1991年に西日本の主要養殖県に発生域が拡大した養殖マダイの大量斃死の原因究明を行った結果, 以下のことが明らかとなった。 1.病魚の外観は体色の黒化や褪色, 体表や鰭の出血性のスレを特徴とし, 剖検すると鯉の褪色, 鰓弁の点状出血や先端部からの出血, 囲心腔内の出血等が観察された。 2.病理組織学的には脾臓組織のほか, 心臓の心内膜下, 鰓の中心静脈洞内皮および中肋の軟骨膜に接する組織間隙, 腎臓の間質組織と糸球体に肥大球形化した細胞が多数観察されるのが特徴であった。肝臓ではその出現頻度は低かった。 3.電顕観察ではこれらの異形肥大細胞の細胞質内に平面的には6角形を呈する, 直径が200～240nmのウイルス粒子の増殖像が観察された ...

Juvenile bisexuality in the red sea bream,Pagrus major

Environmental Biology of Fishes, 1988
The histology of the gonad of the red sea bream,Pagrus major, was examined in order to study the early gonadal development, sexual maturation and sex ratio in a natural population. A total of 1,117 fish between the ages of 4 months and 8 years were examined.

Ultrastructure of Pagrus major and Rhabdosargus sarba spermatozoa (Perciformes: Sparidae: Sparinae)

Tissue and Cell, 2004
Transmission and scanning electron microscopy were used to investigate the ultrastructure of spermatozoa in two Sparinae species Pagrus major and Rhabdosargus sarba. Ultrastructurally, the spermatozoa of P. major and R. sarba both consist of a spherical, homogeneously electron-dense nucleus with a deep axial nuclear fossa, and an unusual notch, in the ...

Feeding Ecology of Red Seabream, Pagrus major (Sparidae) in the Korea Strait

Journal of Ichthyology, 2023
The feeding ecology of red seabream, Pagrus major was studied using 1046 specimens collected by danish seine and bottom trawl from January to December 2018 in the Korea Strait. The size of the individuals ranged from 18.4 to 70.4 cm in fork length. Red seabream was a carnivore that consumed mainly anthozoans, brachyurans, and cephalopods.

Novel expression of importin α homologue in marine teleost, Pagrus major

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2008
Importin alpha proteins are critical modulators of the classical nuclear protein import pathway. Although the physiological roles of importin alpha have been extensively studied in invertebrates and mammals, very little is known about their counterparts in lower vertebrates.

Flow cytometry and ultrastructure of cryopreserved red seabream (Pagrus major) sperm

Theriogenology, 2007
The objectives were to assess motility, fertilizing capacity, structural integrity, and mitochondrial function in fresh versus frozen-thawed (15% DMSO was used as a cryoprotectant) sperm from red seabream (Pagrus major). Mean (+/-S.D.) rates of motility, fertilization and hatching of frozen-thawed sperm were 81.0+/-5.4, 92.8+/-1.9, and 91.8+/-5.2 ...

Metagenomic profile of caudal fin morphology of farmed red sea bream Pagrus major

Diseases of Aquatic Organisms, 2023
The morphology of farm-reared fish often differs from that of their wild counterparts, impacting their market value. Two caudal fin tip shapes, acutely angled and blunted, are recognized in farmed populations of red sea bream Pagrus major. The angled form is preferred by consumers over the blunt since it resembles that of wild fish.
