Economic assessment of commercial hatchery production of milkfish (Chanos chanos Forsskal) fry
(John Wiley and Sons, 1999)
The economic viabilities of two types of commercial hatchery milkfish (Chanos chanos) fry operations were assessed and compared. Based on the actual cost of input, the physical facilities, and the potential production ...
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 ...
Survival and growth of bighead carp fry exposed to low salinities
(Kluwer, 1999)
Bighead carp (Aristichthys nobilis Oshima) fry of various ages (11, 18, and 35 days post-hatch) were exposed to the low salinities encountered during the annual intrusion of seawater in Laguna Lake, Philippines. Practical ...
Growth and production of deformed and nondeformed hatchery-bred milkfish (Chanos chanos) in brackishwater ponds
(Society of Israeli Aquaculture and Marine Biotechnology, 1999)
This study evaluated the growth and survival of morphologically deformed and nondeformed hatchery-bred milkfish in brackishwater ponds. It compared the size-frequency distribution of the nondeformed fish with the deformed ...
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 ...
Sustained production of milt in rabbitfish, Siganus guttatus Bloch, by weekly injection of luteinizing hormone-releasing hormone analogue (LHRHa)
(Elsevier, 1993)
Mature male rabbitfish (Siganus guttatus Bloch) received weekly injections of 200 μg of luteinizing hormone-releasing hormone analogue (D-Ala<sup>6</sup>, Pro<sup>9</sup>-LHRH-ethylamide) per kg body weight for 5 consecutive ...
Spawning response latency and egg production capacity of LHRHa-injected mature female sea bass, Lates calcarifer Bloch
(Blackwell Publishing, 1990)
Mature female sea bass (Lates calcarifer Bloch) were injected once intramuscularly with 20 μg luteinizing hormone-releasing hormone analogue (D-Ala<sup>6</sup>, Pro<sup>9</sup>-LHRH-ethylamide) per kg body weight (BW) at ...
Milt-egg ratio in artificial fertilization of the Asian freshwater catfish, Clarias macrocephalus, injected salmon gonadotropin-releasing hormone analogue and domperidone
(Cambridge University Press, 1995)
The author deals with the catfish Clarias macrocephalus which are artificially fertilized by inducing females to spawn using various hormones. This paper investigates the effect of Ovaprim on milt production and fertilizing ...
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 ...
Spermiation response of mature rabbitfish, Siganus guttatus Bloch, to luteinizing hormone-releasing hormone analogue (LHRHa) injection
(Elsevier, 1991)
A method to quantify the spermiation response of mature rabbitfish to hormonal therapy is described. Spermatocrit or packed sperm volume was measured after milt loaded in non-heparinized microhematocrit capillary tubes was ...
