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 ...
Sustained hormone release. III. Use of gonadotropin releasing hormone analogues to induce multiple spawnings in sea bass, Lates calcarifer
(Elsevier, 1988)
Two gonadotropin releasing hormone analogues (GnRHa), [D-Ala<sup>6</sup>, Pro<sup>9</sup>-ethylamide] mammalian GnRH and [D-Arg<sup>6</sup>, Pro<sup>9</sup>-ethylamide] salmon GnRH, were shown to induce spawning in see ...
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, ...
Induced gonadal maturation and rematuration in milkfish: Limited success with chronic administration of testosterone and gonadotropin-releasing hormone analogues (GnRH-A)
(Elsevier, 1988)
Nine experiments were conducted to investigate the influence of chronic administration of testosterone (T) and gonadotropin-releasing hormone (GnRH) analogues on first maturation of 4- to 6-year-old fish and rematuration ...
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 ...
Multiple gonadal maturation and re-maturation after hormone-induced spawning in bighead carp Aristichthys nobilis Rich.
(San Carlos Publications, University of San Carlos, 1991)
Gonadal maturation and rematuration after hormone-induced spawning in cage-reared female bighead carp Aristichthys nobilis were observed. Percent maturation ranged from 54 to 100% for females and 0 to 40% for males. ...
Milt production of sea bass Lates calcarifer Bloch administered an analogue of luteinizing hormone-releasing hormone and 17α-methyltestosterone
(Society of Israeli Aquaculture and Marine Biotechnology, 2002)
The milt production responses of sexually mature sea bass Lates calcarifer to (D-Ala<sup>6</sup>, Pro<sup>9</sup>-N- ethylamide) luteinizing hormone-releasing hormone (LHRHa) and 17α-methyltestosterone injections were ...
Bioactivity of stored luteinizing hormone-releasing analogue (LHRHa) in sea bass, Lates calcarifer Bloch
(Wiley-Blackwell, 1996)
The spawning induction activity of dissolved and pelleted (D-Ala<sup>6</sup>, Pro<sup>9</sup> N ethylamide) luteinizing hormone-releasing hormone analogue (LHRHa) stored for various periods was assessed in mature female ...
