Effects of exogenous hormones and broodstock age on the spawning response of captive silver therapon Leiopotherapon plumbeus
(Wiley, 2022)
Evaluation of appropriate hormone and ideal broodstock age for optimal breeding efficiency may ensure the production of good quality eggs and larvae in the hatchery. In this study, the spawning response of captive silver ...
GABA enhances reproduction of the rotifer Brachionus plicatilis Muller: application to mass culture
(Wiley-Blackwell, 2000)
Based on the results of individual and batch culture experiments in small volumes, we conducted experiments in larger volumes of 100 mL, 1 L and 10 L to determine: (1) at what phase of population growth would gamma-aminobutyric ...
Induced spawning by LHRHa and pimozide in the Asian catfish Clarias macrocephalus (Gunther)
(Blackwell Publishing, 1993)
Experiments were conducted to determine the optimum dose of luteinizing hormone-releasing hormone analogue (LHRHa) and pimozide (PIM) injected simultaneously to yield a high ovulation rate and produce sufficient eggs in ...
Biomass and reproductive states of Gracilaria heteroclada Zhang et Xia collected from Jaro, central Philippines
(Walter de Gruyter, 1996)
Biomass production and reproductive states were investigated to determine the abundance of Gracilaria heteroclada Zhang et Xia at Jaro, central Philippines from March 1990 to February 1991. Biomass of Gracilaria heteroclada ...
Effect of growth hormone and γ-aminobutyric acid on Brachionus plicatilis (Rotifera) reproduction at low food or high ammonia levels
(Elsevier, 1999)
Growth hormone (GH, 0.0025 and 0.025 I.U. ml<sup>−1</sup>) and γ-aminobutyric acid (GABA, 50 μg ml<sup>−1</sup>) enhance rotifer population growth in batch cultures. In order to further understand the mechanism of their ...
Effect of juvenile hormone and serotonin (5-HT) on mixis induction of the rotifer Brachionus plicatilis Muller
(Elsevier, 2000)
Juvenile hormone (JH) and serotonin (5-HT) were previously shown to enhance mictic (sexual) female production of the rotifer Brachionus plicatilis in batch cultures. To explore the basis of these effects, experiments were ...
Testicular histology and serum steroid hormone profiles in hatchery-bred catfish Clarias macrocephalus (Gunther) during an annual reproductive cycle
(Japanese Society of Fisheries Science, 1997)
Testicular development, gonadosomatic index (GSI), and related steroid hormones (testosterone or T, 11-ketotestosterone or 11-KT, 17α, 20β-dihydroxy-4-pregnen-3-one or DHP) in serum were monitored during an annual reproductive ...
Ovarian development and changes in the serum vitellogenin levels in the river sculpin, Cottus hangiongensis, during an annual reproductive cycle
(Faculty of Fisheries, Hokkaido University, 1989)
Annual changes in the ovarian development and serum vitellogenin concentration were investigated in the river sculpin, Cottus hangiongensis, sampled monthly from a river in southern Hokkaido, Japan. Ovarian development ...
Development of a giant grouper Luteinizing Hormone (LH) Enzyme-Linked Immunosorbent Assay (ELISA) and its use towards understanding sexual development in grouper
(Elsevier, 2020-07-13)
A recombinant giant grouper Luteinizing Hormone (LH) consisting of tethered beta and alpha subunits was produced in a yeast expression system. The giant grouper LH β-subunit was also produced and administered to rabbits ...
Development of specific enzyme-linked immunosorbent assay for yellowtail kingfish (Seriola lalandi) follicle stimulating hormone using recombinant gonadotropins
(Elsevier, 2019)
We developed a specific competitive enzyme-linked immunosorbent assay (ELISA) for yellowtail kingfish (Seriola lalandi) follicle stimulating hormone (FSH). We previously produced a full-length single chain recombinant ...
