Effect of light quality and eyestalk ablation on ovarian maturation in Penaeus monodon
Prawns were subjected to the following treatments: blue light, red light, natural light, and natural light plus unilateral eyestalk ablation. Unablated prawns under blue and natural light developed stage III ovaries; under ...
Induced maturation and spawning in five-month-old Penaeus monodon Fabricius by eyestalk ablation
(Elsevier, 1978)
Pond-reared sugpo (Penaeus monodon Fabricius) females from coastal fry harvested after 4 months were unilaterally ablated and stocked in an indoor concrete tank with an equal number of males. The first two spawnings were ...
Sea bass (Lates calcarifer Bloch) reproduction in captivity: a research update
(Asian Fisheries Society, 1994)
Recent advaces in the spontaneous and hormoneinduced breeding of caged sea bass (Lates calcarifer bloch, Family Centropomidae) are reviewed. Spontaneous spawnings follow a semilunar rhythm, with most spawings accurring in ...
LHRHa and pimozide-induced breeding in the catfish, Clarias macrocephalus (Gunther).
(1994)
Clarias macrocephalus is endemaic yet dwinding freshwater foodfish in the Philippines. Induced breeding protocol was developed after a series of studies which determined the appropriate egg size, proper time of stripping ...
Maturation and induced spawning of the mangrove red snapper (Lutjanus argentimaculatus) reared in a floating net cage in the Philippines
(International Center for Living Aquatic Resources Management (ICLARM), 1996)
Wild-caught mangrove red snapper (Lutjanus argentimaculatus) were reared in a floating net cage at SEAFDEC/AQD's Igang Marine Substation at Guimaras Island, Central Philippines. In 1993, monthly samplings and induced ...
Induced maturation and spawning of milkfish, Chanos chanos Forsskal, by hormone implantation
(Elsevier, 1986)
The milkfish, Chanos chanos Forsskal, does not reach gonadal maturity easily in captivity. In an attempt to induce maturation, exogenous hormones, LHRH-A and 17α-methyl-testosterone, were implanted into adult milkfish ...
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). ...
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 ...
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 ...
