Hormonal changes accompanying sexual maturation in captive milkfish (Chanos chanos Forsskal)
(Springer Verlag, 1992)
Steroid hormone profiles accompanying sexual maturation in captive milkfish are described. There were no significant differences in levels of serum estradiol 17-β (E<sub>2</sub>) and testosterone (T) between immature male ...
Light color and ovarian maturation in unablated and ablated giant tiger prawn Penaeus monodon (Fabricius)
(Elsevier, 1992)
The effect of light color (green, blue and white fluorescent lights, with natural light as a control) on maturation in intact and eyestalk-ablated Penaeus monodon was tested in 12-m<sup>3</sup> broodstock tanks. Size and ...
Advancement of sexual maturation and spawning of sea bass, Lates calcarifer (Bloch), using pelleted luteinizing hormone-releasing hormone analogue and 17α-methyltestosterone.
(Elsevier, 1990)
The ability of luteinizing hormone-releasing hormone analogue [(D-Ala<sup>6</sup>, Pro<sup>9</sup>-NEt)LHRH], 17α-methyltestosterone (MT), and their combination to advance gonadal maturation and spawning in captive sea ...
Notes on the induced spawning, embryonic and larval development of the window-pane shell, Placuna placenta (Linnaeus, 1758), in the laboratory
(Elsevier, 1997)
Intragonadal injection of 0.5 ml of a 2-mM serotonin solution or seawater irradiated by ultraviolet (UV) light (925–1395 mW h/l) induced spawning in male and female window-pane shell, Placuna placenta (Linnaeus, 1758). ...
Growth, maturity and induced spawning of mangrove red snapper, Lutjanus argentimaculatus, broodstock reared in concrete tanks
(Society of Israeli Aquaculture and Marine Biotechnology, 1999)
Mangrove red snapper, Lutjanus argentimaculatus, fry (n=30) were collected in 1993 and reared in concrete tanks. They were fed trash fish every other day initially at 10% to 5%, until they reached three years. They reached ...
Induction of sex inversion in juvenile grouper, Epinephelus suillus, (Valenciennes) by injections of 17α-Methyltestosterone
(The Ichthyological Society of Japan, 1994)
Four groups of two-year old juvenile groupers (Epinephelus suillus), each with 8-9 individuals of mean body weight (BW) 1.2 kg, were treated with 17α-methyltestosterone (MT). MT was injected intramuscularly within the range ...
A comparison of the annual changes in testicular activity and serum androgen levels between the early and delayed maturing groups of male Cottus hangiongensis
(Springer Verlag, 1992)
Annual changes in testicular activity and concentration of two serum androgens were monitored in two groups of the river-sculpin Cottus hangiongensis collected from the upper and lower reaches of a river at southern Hokkaido, ...
Ovarian changes and female-specific protein levels during sexual maturation of the white shrimp Penaeus indicus
(Society of Israeli Aquaculture and Marine Biotechnology, 1992)
The histological changes in the ovary and female-specific protein levels in the hemolymph during sexual maturation of Penaeus indicus were determined. Ovarian maturation was classified into four stages: immature stage, ...
LHRH-a and domperidone-induced oocyte maturation and ovulation in bighead carp, Aristichthys nobilis (Richardson)
(Elsevier, 1991)
Effects of intraperitoneal injections of LHRH-a and domperidone (DOM), given singly or in combination at two injections, on oocyte maturation, ovulation and spawning in bighead carp, Aristichthys nobilis, were investigated. ...
Lunar synchronization of spawning in sea bass, Lates calcarifer (Bloch): Effect of luteinizing hormone-releasing hormone analogue (LHRHa) treatment
(Wiley-Blackwell, 1992)
Based on egg collection records, spontaneous spawning activity of sea bass, Lates calcarifer (Bloch), reared in floating net cages followed a semilunar cycle. The peak of multiple spawnings coincided with declining spring ...
