Larval rearing of bighead carp, Aristichthys nobilis Richardson, using different types of feed and their combinations
(Blackwell Publishing, 1988)The effects of different types of feed, given singly or in combination, on the growth and survival of bighead carp, Arislichlhys nobilis Richardson, larvae reared for a period of 12 weeks were determined. Growth was highest ... -
Water hardness determination using local laundry bar soaps for carp hatcheries
(Fisheries Research Society of the Philippines, 1988)A simple method using local laundry soap is described for carp hatchery operation. A saturated soap solution was prepared and uses to titrate a 100-ml water sample of known hardness until a permanent lather appeared on the ... -
Improved larval survival at metamorphosis of Asian seabass (Lates calcarifer) using ω3-HUFA-enriched live food
(Elsevier, 1990)Asian seabass (Lates calcarifer) larvae were fed Brachionus cultured on Chlorella and, as soon as ingestin was possible, different types of Artemia, i.e., nauplii of the San Francisco Bay (SFB) strain, Great Salt Lake (GSL) ... -
The effects of Vibrio anguillarum extracellular products on Japanese eels
(Elsevier, 1989)To test the effect of Vibrio anguillarum extracellular products (ECP) on Japanese eels (Anguilla japonica ), test fish were injected intramuscularly with ECP at a dose of 1 mg protein/100 g body weight of fish.At 3,6,12,24 ... -
Effects of continuous lighting on growth and survival of first-feeding larval rabbitfish, Siganus guttatus
(Elsevier, 1988)The effects of 24-h lighting on feeding, growth and survival of first-feeding larvae of Siganus guttatus were tested. Continuous light gave a higher mean survival (31.69%) with a maximum of 40.50% compared to natural ... -
Tissue distribution of mercury and selenium in minnows, Phoxinus phoxinus
(Springer Verlag, 1990)The protective effect of selenium against mercury toxicity has been extensively demonstrated in a number of studies (Burke eta]. 1977; Kasuya 1976). Since mercury uptake is not always diminished by the presence of selenium ... -
Effect of storage temperature on the quality of diets for the prawn, Penaeus monodon Fabricius
(Elsevier, 1989)The effect of storage temperature was evaluated on the basis of growth response of prawns fed for 10 weeks with diets stored at 0°C, 10°C, 28°C-31°C (ambient temperatures) and 40°C for a period of 10 weeks. Prawns were ... -
Uptake and elimination of iodine-131 by the freshwater clam Corbicula manilensis Philippi from water
(College of Arts and Sciences, University of the Philippines, 1988)Whole body uptake of Iodine-131 by the freshwater clam, Corbicula manilensis, from contaminated water was followed using NaI scintillation counter. The bioaccumulation factor (BF) exclusive of shell was 5.44. The degree ... -
Mercury levels in the sediment, water, and selected finfishes of Laguna Lake, the Philippines
(Elsevier, 1990)Monthly samples of sediment, water and commercially important species of fish, primarily Oreochromis niloticus and Chanos chanos , plus a few other species, were collected from the West Bay area of Laguna Lake, The Philippines ... -
Cage culture of Oreochromis aureus and Oreochromis niloticus hybrids in Laguna Lake, Philippines
(Taylor & Francis, 1988)A reciprocal cross of male Oreochromis aureus and female Oreochromis niloticus were made to produce the hybrids stocked in cages in Laguna Lake, Philippines with and without feeding. The growth rates of the hybrids from ... -
Quantitative lysine requirement of milkfish (Chanos chanos) juveniles
(Elsevier, 1990)A feeding experiment was conducted to determine the quantitative dietary requirement of milkfish juveniles for lysine. Milkfish (Chanoschanos Forsskal) of mean weight 5.92±0.14 g were fed diets containing 7.0, 11.0, 15.0, ... -
Uptake and elimination of inorganic mercury and selenium by minnows Phoxinus phoxinus
(Elsevier, 1988)Minnows were kept in aquaria containing filtered water dosed with measured amounts of mercury as mercuric chloride and selenium as sodium selenate. Fishes exposed to selenium in combination with mercury showed significantly ... -
Acute toxicity of potassium permanganate to milkfish fingerlings, Chanos chanos
(Springer Verlag, 1989)Potassium permanganate (KMnO4) is a strong oxidizing agent and is commonly used in aquatic systems to improve available oxygen, treat infectious diseases and parasites, detoxify fish poisons, and control algae. ... -
Studies on the digestive lipases of milkfish, Chanos chanos
(Elsevier, 1990)Milkfish grown on two natural foods were examined to determine the distribution pattern of the digestive lipases along the digestive tract and to identify the optimum condition for lipase activity. One food consisted of a ... -
The effect of dietary protein-energy levels on growth and metabolism of milkfish (Chanos chanos Forsskal)
(Elsevier, 1988)- Groups of milkfish juveniles (mean weight, 2.8 g) were fed diets containing white fishmeal and gelatin with varying protein-energy to total metabolizable energy (PE:TME) ratios.
- Amino acids were incorporated ...

Growth and survival of bighead carp (Aristichthys nobilis) fry fed at different intake levels and feeding frequencies
(Elsevier, 1988)This study was conducted to assess the effect of different levels of dietary intake and feeding frequencies on growth and survival of bigheadcarp, Aristichthys nobilis, fry. The feeding rates consisted of 10%, 20%, and 30% ... -
Tolerance level and histopathological response of milkfish (Chanos chanos) fingerlings to formalin
(Elsevier, 1989)Static 96-h bioassays were conducted on milkfish (Chanos chanos ) fingerlings with formalin at concentrations ranging from 50 to 500 ppm. The 24-, 48-, 72-, and 96-h median lethal concentration values (LC50) were 322, 260, ... -
HCG and LHRH-A induced spawning in bighead carp Aristichthys nobilis Rich. reared in floating cages in Laguna de Bay
(San Carlos Publications, University of San Carlos, 1989)Hormone-induction of spawning in bighead carp Aristichthys nobilis Rich. by single or double intraperitoneal injection with varying combined dosages of HCG and LHRH-A was conducted. Fish were spawned successfully following ... -
Apparent digestibility of diets with various carbohydrate levels and the growth response of Penaeus monodon
(Elsevier, 1991)The digestibility of four isonitrogenous practical diets (40% crude protein) containing different levels (5%, 15%, 25% and 35%) of gelatinized breadflour as carbohydrate source were determined for P. monodon (average weight ... -
