Larval intervals of the sea bass, Lates calcarifer, based on the development of swimming and feeding functions.
(Asian Fisheries Society, 1994)
Developmental sequences of characters concerned in swimming and feeding function were examined on laboratory-reared seabass larvae. Based on a scheme of development events constructed in this study, the early life hisory ...
Natural spawning, egg and fry production of milkfish, Chanos chanos (Forsskal), broodstock reared in concrete tanks
(Blackwell Publishing, 1994)
Gonadal maturation, rematuration, and spawning of nine- (1982 stock) and ten-year-old (1981 stock) milkfish reared in 150 and 200 m<sup>3</sup> concrete tanks were observed in 1990 and 1991. From 23 September to 9 November ...
Acute toxicity of nifurpirinol, a fish chemotherapeutant, to milkfish (Chanos chanos) fingerlings
(Springer Verlag, 1994)
Nifurpirinol (trade name Furanace and originally known as P-7138), is a nitrofuran derivative synthesized by the Dainippon Pharmaceutical Co. Ltd., Japan, and was developed exclusively as a broad-spectrum antibiotic for ...
Feeding live or frozen Moina macrocopa (Strauss) to Asian sea bass, Lates calcarifer (Bloch), larvae
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)
Growth and survival of hatchery-reared sea bass, Lates calcarifer, larvae fed live or frozen Moina macrocopa were determined, In Experiment 1, Moina was fed to sea bass of different sizes: 3.6 mm, 5.5 mm and 7.6 mm standard ...
Changes in the steroid hormone and vitellogenin levels during the gametogenic cycle of the giant tiger shrimp, Penaeus monodon
(Elsevier, 1994)
The levels of estradiol-17β, and progesterone in the hemolymph, ovaries and hepatopancreas, in relation to the vitellogenin levels of captive female Penaeus monodon, were determined during the gametogenic cycle. Estradiol ...
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 ...
The effect of lipid-enriched broodstock diets on spawning and on egg and larval quality of hatchery-bred rabbitfish (Siganus guttatus)
(San Carlos Publications, University of San Carlos, 1994)
Three isocaloric and isonitrogenous diets formulated to contain 12 (diet A), 15 (B) and 18% (C) lipids were tested on hatchery-bred rabbitfish Siganus guttatus broodstock to determine their effect on spawning and quality ...

(Elsevier, 1994)
Two Nile tilapia strains of Oreochromis niloticus (L.) (Cichlidae, Teleostei) fingerlings were exposed to mixtures of zinc, cadmium and mercury. The two strains used were Chitralada or NIFI (originally from the National ...
Oral delivery in aquaculture: Controlled release of proteins from chitosan-alginate microcapsules
(Aquacultural Engineering Society (AES), 1994)
Potentially, the most useful method of fish vaccination is oral administration. However, this technique is presently only partially effective because of the apparent destruction of the vaccine in the fish digestive system, ...
Effect of pH and ammonia on survival and growth of the early larval stages of Penaeus monodon Fabricius
(Elsevier, 1994)
Lethal toxicity tests of ammonia at different pH levels (7, 7.5, 8, and 8.5) and its effect on survival and growth of the early larval stages of Penaeus monodon were determined. An increase in ammonia toxicity when the ...
