Effect of substrate types on fecundity and nauplii production of ablated Penaeus monodon Fabricius
(Science and Technology Information Institute, Department of Science and Technology, 1980)
The survival, spawning, fecundity, and nauplii production of ablated Penaeus monodon females reared in flow-through broodstock tanks with white coralline and black sand substrates for 62 days, were assessed. Prawns exposed ...
The length-weight relationship, food habits and condition factor of wild juvenile milkfish in Sri Lanka
(Elsevier, 1986)
Wild juvenile milkfish (Chanos chanos) were obtained from Negombo lagoon in September 1984. Thirty-one specimens (92–186 mm FL) had a fork length-body weight relationship of log W = −5.6083 + 3.2598 log L. These fish were ...
Collection of naturally-spawned milkfish eggs in floating cages
(Asian Fisheries Society, 1986)
Natural spawnings of milkfish from floating cages were obtained from different stocks of 5-7 year-old milkfish in 1980, 1981, 1983 and 1985. The maximum number of eggs collected in 1980, using a series of 1-m diameter ...
Spontaneous maturation and spawning of milkfish in floating net cages
(Elsevier, 1986)
Milkfish (Chanos chanos Forsskal) reared from wild-caught fry and from hatchery-bred fry matured at 3.5-5.5 years (2.3-4.9 kg). Maturation and spawning of the hatcherybred fish marks the first time the milkfish life-cycle ...
Induced spawning and larval rearing of grouper (Epinephelus salmoides Maxwell)
(1986)
Broodfish of grouper (Epinephelus salmoides ) were induced to spawn by hormonal induction. The hormones used for this experiment were HCG + pituitary gland (PG) and LRH-a. The results showed that at dosages of 500 IU HCG ...
Spawning response of mature female sea bass, Lates calcarifer (Bloch), to a single injection of luteinizing hormone-releasing hormone analogue: effect of dose and initial oocyte size
(Blackwell Publishing, 1989)
The effect of various doses of luteinizing hormone-releasing hormone analogue (LHRHa) ranging from 1 to 100 μg/kg body weight on the spawning response of mature female sea bass, Lates calcarifer (Bloch) was tested. A single ...
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 ...
The effect of stress on spawning of brood fish and survival of larvae of the rabbitfish, Siganus guttatus (Bloch)
(Elsevier, 1989)
The effects of stress due to handling, and repeated sham and human chorionic gonadotropin (HCG) injections on spawning and survival of the rabbitfish, Siganus guttatus were studied. Results showed that stress significantly ...
Spawning behavior and early life history of the rabbitfish, Siganus guttatus, in the laboratory
(Elsevier, 1986)
The spawning behavior and embryonic and larval development of Siganus guttatus are described from laboratory observations. Characteristic prespawning behavior began 4 h before actual spawning: the female touched the anal ...
Induced spawning of sea bass, Lates calcarifer, and rabbitfish, Siganus guttatus, after implantation of pelleted LHRH analogue
(Elsevier, 1985)
Captive Lates calcarifer broodstock at Tigbauan, Iloilo (Philippines) were implanted with cholesterol-based pellets of the LHRH analogue D-Trp<sup>6</sup>-desGly<sup>10</sup>-LHRH ethylamide or D-hArg(Et<sub>2</sub>)<sup>6</sup>, ...
