Effects of feeding frequency and amount of feeding on the growth of the grouper, Epinephelus malabaricus
(Science and Technology Information Institute, 1989)The effects of feeding frequency and amount of food on the growth of juvenile groupers (Epinephelus malabaricus) were investigated for 12 weeks of rearing in net-cages set in an earthen pond. The juveniles (110-130 g in ... -
Development of an ovarian biopsy technique in the sea bass, Lates calcarifer (Bloch).
(Elsevier, 1989)A convenient and rapid biopsy method for taking ovarian samples from mature sea bass (Lates calcarifer Bloch) is described. Intra-ovarian oocytes siphoned with polyethylene tubing from any region of the ovary provide a ... -

(Elsevier, 1989)The induction of sequential spawnings of mature female sea bass following intraperitoneal implantation of various doses of luteinizing hormone-releasing hormone analogue (LHRHa) in a 95% cholesterol pellet was investigated. ... -
Meristic variations in milkfish Chanos chanos from Philippine waters
(Springer Verlag, 1988)Variations in meristic characters occur within and between samples of milkfish Chanos chanos (Forsskal) collected on June 1977 from five localities in Philippine waters. The unbranched anal and ventral fin rays are the ... -
Carbohydrate, nitrogen and protein content of kinetin-treated Azolla pinnata var. imbricata plants.
(College of Arts and Sciences, University of the Philippines, 1988)The influence of various levels of kinetin on growth, carbohydrate, nitrogen, and protein content of Azolla pinnata var. imbricata plants cultured in a nitrogen-free 40% Hoagland’s solution under greenhouse conditions was ... -
Amino acid requirements for growth of Nile tilapia
(American Society for Nutrition, 1988)A series of feeding experiments was conducted in aquaria to determine the quantitative requirements of the 10 essential amino acids for growth of young Nile tilapia (Oreochromis niloticus). The test diets contained casein ... -
Reproductive performance and growth of Nile tilapia (Oreochromis niloticus) broodstock fed diets containing Leucaena leucocephala leaf meal
(Elsevier, 1988)The effects of dietary leucaena leaf meal on reproductive performance and growth of Nile tilapia were determined. In the preliminary trial, sexually mature Nile tilapia were fed with a control diet or a test diet which had ... -
Limnological notes on the finfish production problem of Laguna de Bay.
(College of Arts and Sciences, University of the Philippines, 1988)Environmental problems have significantly affected fishery production and management in Laguna de Bay, the largest lake in the Philippines. Fishermen and fishpen operators are complaining about the slow growth of fish and ... -
Effects of various diets on the nutritional value of Artemia sp. as food for the prawn Penaeus monodon
(Springer Verlag, 1988)The nutritional value of Artemia sp. as food for marine fish and crustacean larvae has been linked to the level of its polyunsaturated fatty acid (PUFA) content. Experiments in August 1984 were conducted to determine the ... -
Induced spawning of maturing milkfish (Chanos chanos) using human chorionic gonadotropin and mammalian and salmon gonadotropin releasing hormone analogues
(Elsevier, 1988)The response of maturing female milkfish to D-Ala6-des Gly10 mammalian GnRH ethylamide (mGnRH-A), D-Arg6-des Gly10 salmon GnRH ethylamide (sGnRH-A) and human chorionic gonadotropin ... -
Induced gonadal maturation and rematuration in milkfish: Limited success with chronic administration of testosterone and gonadotropin-releasing hormone analogues (GnRH-A)
(Elsevier, 1988)Nine experiments were conducted to investigate the influence of chronic administration of testosterone (T) and gonadotropin-releasing hormone (GnRH) analogues on first maturation of 4- to 6-year-old fish and rematuration ... -
An improved method for collecting naturally spawned milkfish eggs from floating cages
(Elsevier, 1988)Natural spawnings of captive milkfish (Chanos chanos Forsskal) held in floating cages were observed in 1980, 1981, 1983 and 1985. Frequency of spawnings increased from two in 1980 to 41 in 1985. Various collectors and ... -
Sodium-EDTA effects on survival and metamorphosis of Penaeus monodon larvae
(Elsevier, 1988)The effects of Na-EDTA on growth and survival of Penaeus monodon larvae were determined for applications given daily or every 3 days. Application of 2.0, 5.0, and 10.0 ppm were given on day 1, day 4 and day 7 in Experiment ... -
Transition from endogenous to exogenous nutrition sources in larval rabbitfish Siganus guttatus
(Japanese Society of Fisheries Science, 1988)The early larval development of Siganus guttatus was studied with emphasis on the transition from endogenous to exogenous feeding. Three rearing trials were conducted as follows: 1) rearing in a 5 ton concrete tank at ... -
Aeromonas hydrophila associated with ulcerative disease epizootic in Laguna de Bay, Philippines
(Elsevier, 1987)Aeromonas hydrophila was consistently associated with necrotic ulcers and lesions in mudfish/snakehead (Ophiocephalus striatus), Thai catfish (Clarias batrachus), crucian carp (Carassius carassius) and goby (Glossogobius ... -
Morphological aspects of the development of swimming and feeding functions in the milkfish Chanos chanos
(The Ichthyological Society of Japan, 1987)Development of swimming and feeding abilities based on morphological development of larval and early juvenileChanos chanos was investigated. In larvae smaller than about 6.5 mm SL, mechanical supports of fins and branchial ... -
Effects of Chlorella-feeding on larval milkfish, Chanos chanos, as evidenced by histological monitoring
(Elsevier, 1987)Milkfish, Chanos chanos, larvae were found to suffer 100% mortality within 6 days of feeding when reared on Chlorella sp. According to the liver ultrastructure, Chlorella-fed fish underwent starvation. Likewise, no signs ... -
Nutrition-related histopathology of the intestine of milkfish Chanos chanos fry
