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 m3 concrete tanks were observed in 1990 and 1991. From 23 September to 9 November ... -
Induced spawning and early life description of the mangrove red snapper, Lutjanus argentimaculatus
(Elsevier, 1994)Wild-caught mangrove red snapper, Lutjanus argentimaculatus, reared in a concrete tank for 1 year, spontaneously matured in June 1992. On 19 August 1992, a sexually mature female and male (4.6 and 3.2 kg body weight, ... -
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 ... -
Multi-species fish hatchery
(Society of Aquaculture Engineers of the Philippines, Inc., 1994)Due to the unpredictable market demand and market value of penaeid shrimp, the shrimp hatchery which is an industry in itself suffered heavy losses. Shrimp hatchery operators are now interested in marine finfish culture. ... -
Daily rates of ingestion on rotifers and Artemia nauplii by laboratory-reared grouper larvae of Epinephelus suillus
(San Carlos Publications, University of San Carlos, 1994)The amount of rotifers and Artemia nauplii consumed daily by the grouper Epinephelus suillus larvae was determined through examination of gut contents. The larvae (2.6 mm TL) were initially fed rotifers on day 2 and newly ... -
Thyroid hormone surges during milkfish metamorphosis
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)Both thyroxine (T4) and triiodothyronine (T3) were detected in fertilized eggs and larvae of milkfish. The concentration of T4 was lower than that of T3 only in fertilized eggs ... -
Survival and heavy metal accumulation of two Oreochromis niloticus (L.) strains exposed to mixtures of zinc, cadmium and mercury
(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 ... -
Vaccination of European sea bass fry through bioencapsulation of Artemia nauplii
(European Aquaculture Society, 1994)European sea bass (Dicentrarchus labrax) fry vaccinated orally via bioencapsulation in Artemia nauplii or by bath method exhibited better performance than control fish in terms of growth, food conversion and resistance to ... -
L-ascorbyl-2-phosphate Mg as source of vitamin C for juvenile Penaeus monodon
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)Phosphated ascorbic acid (MAP), a stable vitamin C derivative, was used in practical diets for Penaeus monodon (wet weight, 126-254 mg) as a source of vitamin C. In Experiment I, the levels were from 0 to 1,500 ppm MAP. ... -
Gill lesions in Nile tilapia Oreochromis fingerling associated with acute malathion poisoning.
(Science and Technology Information Institute, 1994)The hispathological changes in gills of Nile tilapia, Oreochromis niloticus, fingerlings exposed to 5.3 mg/l (96-h LC50) malathion are described. These changes include hypertrophy of epithelial cells after 3 h, epithelial ... -
