Development of a homologous radioimmunoassay for red seabream follicle stimulating hormone and regulation of gonadotropins by GnRH in red seabream, Pagrus major

General and Comparative Endocrinology, 2016
Using a recombinant chimeric single-chain follicle stimulating hormone (FSH), we established a radioimmunoassay (RIA) for red seabream (Pagrus major) FSH (pmFSH) which became a powerful tool for studying reproductive physiology. We studied the profiles in plasma and pituitary concentrations of FSH and luteinizing hormone (LH) during sexual maturation ...

The isolation of intestinal microflora of farmed red seabream (Pagrus major) and black seabream (Acanthopagrus schlegeli) at larval and juvenile stages

Aquaculture, 1987
The aerobic bacterial flora in the intestine of farmed red seabream and black seabream was investigated at their larval and juvenile stages in relation to the microflora of ambient water and diets. The total bacterial number in the intestine was 7.4×104 and 3.4×104 colony-forming units (CFU)/fish for red seabream and black seabream, respectively. Among

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.

Seasonal change in collagen content of red seabream muscle

Fisheries Science, 2000
SUMMARY: To investigate the correlation between firmness and the collagen content in fish muscle, we evaluated the seasonal change in collagen content of red seabream muscle on the basis of the content of protein-form hydroxyproline. Since a significant difference was observed among the ratios of proline (Pro) hydroxylation in female fish (P

Inorganic nitrogen compounds reduce immunity and induce oxidative stress in red seabream

Fish & Shellfish Immunology, 2020
In this study, the effect of ammonia derived from different stocking densities on immunological, hematological, and oxidative stress parameters was analyzed in the blood or liver of red seabream. Density- and time-dependent increases in inorganic nitrogen compounds were measured for 20 days by analyzing the three major inorganic nitrogen compounds ...

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 ...

Distinct expression of GnRH genes in the red seabream brain

Fish Physiology and Biochemistry, 1997
This paper reports the molecular cloning of a cDNA encoding the precursor of seabream gonadotropin-releasing hormone (prepro-sbGnRH) and the localization of salmon GnRH (sGnRH) and seabream GnRH (sbGnRH) expressing neurons in the brain of the red seabream (Pagrus major). The cloned prepro-sbGnRH cDNA has a 285 bps open reading frame encoding a 23 amino

Effect of cryoprotectants on hatching rate of red seabream (Pagrus major) embryos

Theriogenology, 2008
The objectives were to investigate the effect of cryoprotectants on the hatching rate of red seabream embryos. Heart-beat embryos were immersed in: five permeable cryoprotectants, dimethyl sulfoxide (DMSO), glycerol (Gly), methanol (MeOH), 1,2-propylene glycol (PG), and ethylene glycol (EG), in concentrations of 5-30% for 10, 30, or 60 min; and two non-
