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 ... -
Aflatoxin B1 contamination of shrimp feeds and its effect on growth and hepatopancreas of pre-adult Penaeus monodon
(Society of Chemical Industry, 1994)A survey of aflatoxin B1 (AFLB1) levels in commonly used commercial shrimp finisher feeds in the Philippines showed a various range of values from not detected to 120 μg kg−1 using ... -
Systematics, distribution, genetics and life history of milkfish, Chanos chanos
(Springer Verlag, 1994)Chanos chanos belongs to a monotypic gonorynchiform family and is most closely related to the freshwater Ostariophysi. The earliest gonorynchiforms occurred in the Cretaceous of Brazil and west Africa. Chanos occurred in ... -
On publishing scientific papers in peer reviewed ISI-covered journals
(San Carlos Publications, University of San Carlos, 1994)This article exhorts university graduate students and researchers everywhere to publish their scientific papers in peer-reviewed journals, preferably those covered by the Institute for Scientific Information (ISI), rather ... -
Ammonia excretion rates of the sea bass, Lates calcarifer, in fresh and sea water
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)The weight-specific ammonia excretion rate of sea bass (Lates calcarifer) fry in fresh water is higher than that of those in sea water. The allometric equation \(y = 24.426 \times ^{-0.4714}\) best describes the relationship ... -
Ammonia excretion in Penaeus monodon postlarvae during handling and transfer
(Society of Israeli Aquaculture and Marine Biotechnology, 1994)The ammonia excretion rate was used as an index of the physiological state of Penaeus monodon poltlarvae (PL) by monitoring excretion rates after handling and transfer to physiologically different media. The ammonia excretion ... -
A critical review of shrimp pond culture in the Philippines
(Taylor & Francis, 1993)The paper reviews and evaluates shrimp pond culture in the Philippines and its ecological and socioeconomic effects. The intertwined histories of the country's mangrove forests and culture ponds are treated in depth; ... -
Salinity tolerance of fertilized eggs and yolk-sac larvae of the rabbitfish Siganus guttatus (Bloch)
(Elsevier, 1993)Among naturally spawned and hormonally induced eggs of Siganus guttatus, salinity levels, at which at least 90% of the eggs hatched, ranged from 7 to 67 ppt for naturally spawned eggs and from 9 to 67 ppt for hormonally ... -
Effect of stocking density and feed on the growth and survival of sea bass fry Lates Calcarifer (Bloch)
(Vidya International Pub., 1993)The effect of two levels of stocking density (5 and 7 m-2) and the two types of feed [trash fish only (TF), and a mixed feed (MF) (mixture of 25% trash fish and 75% commercial pelleted feed)] on the growth, ... -
Effect of burning of rice straw on snails and soil in a brackishwater pond
(Serials Publications, 1993)The effects of burning the varying amounts of dried rice straw on snails and soil properties in brackishwater ponds in the Philippines were evaluated. Cerithium tenellum, Telescopium telescopium and other unidentified snail ... -
Successive spawning of grouper, Epinephelus suillus (Valenciennes), in a tank and a floating net cage
(Elsevier, 1993)Wild Epinephelus suillus (Valenciennes) were collected in 1989 to early 1990. To monitor natural spawning in captivity, 6 mature females (3.5–5.0 kg) and 4 mature males (7–12 kg) were transferred to a 4.6×4.6×2 m concrete ... -
Induced spawning by LHRHa and pimozide in the Asian catfish Clarias macrocephalus (Gunther)
(Blackwell Publishing, 1993)Experiments were conducted to determine the optimum dose of luteinizing hormone-releasing hormone analogue (LHRHa) and pimozide (PIM) injected simultaneously to yield a high ovulation rate and produce sufficient eggs in ...
