Studies on the penaeoid prawns of the Philippines
(Carcinological Society of Japan, 1984)Thirty-five species of penaeoid prawns, representing 9 genera in 3 families, have been found over a period of 5 years from 1976 to 1980 in the Philippine waters. Of these, 15 species have been recorded for the first time ... -
Biological evaluation of phytoplankton (Chlorella sp., Tetraselmis sp. and Isochrysis galbana) as food for milkfish (Chanos chanos) fry.
(Elsevier, 1984)Phytoplankton cultures of Chlorella sp., Tetraselmis sp. and Isochrysis galbana were used alone as feed to rear separate batches of newly caught milkfish (Chanos chanos) fry (about 21 days old). Ultrastructural studies of ... -
Induced breeding and larval rearing experiments with milkfish Chanos chanos (Forskal) in the Philippines
(Elsevier, 1984)Salmon pituitary homogenate was used alone or in combination with human chorionic gonadotropin, to induce spawing in captive and wild adult milkfish at ambient temperature (26–30°C) and salinity of 34%.. Healthy or slightly ... -
Sugar and amino acid transport in fish intestine
(Elsevier, 1984)1. Morphological properties of fish intestines vary with diet. Carnivores have short guts with highly elaborate mucosal folding in the upper intestines; herbivores have long guts which appear structurally uniform from ... -
Occurrence and pathology of an Amyloodinium-like protozoan parasite on gills of grey mullet, Mugil cephalus
(Biologische Anstalt Helgoland, 1984)In cultured grey mullets, Mugil cephalus L., mortalities caused by a dinoflagellate-like parasite were observed under normal rearing conditions. Moribund fish were abnormally swimming near the water surface and exhibited ... -
An investigation of enzyme and other protein polymorphisms in Japanese stocks of the tilapias Oreochromis niloticus and Tilapia zillii
(Elsevier, 1984)Samples of Oreochromis niloticus and Tilapia zillii were collected from the hatcheries of Osaka Prefecture Fisheries Experimental Station and Shiga Prefecture Fisheries Experimental Station, Japan, respectively. The samples ... -
Hormone-induced spawning and embryonic development of the rabbitfish, Siganus vermiculatus (Pisces: Siganidae)
(San Carlos Publications, University of San Carlos, 1984)Induced spawning experiments were conducted on captive Siganus vermiculatus with the use of human chorionic gonadotropin (HCG APL Ayerst). The hormone was administered intramuscularly and the intraovarioan oocyte development ... -
On predicting the setting season of the oyster Crassostrea iredalei in Himamaylan River, Negros Occidental
(University of the Philippines at Los Baños, 1983)A spatfall forecasting program in April-November 1981 suggests that daily counts of larvae in plankton samples may be used to forecast spatfall of C. iredalei . Counts of at least five ready-to-settle larvae per 100-liter ... -
Limnological features of Lake Buluan: Preliminary findings and observations
(Fisheries Research Society of the Philippines, 1983)A limnological survey of Lake Buluan in Mindanao was conducted to evaluate its potentials for fishpen and fish cage culture. The lake was found to be shallow and highly productive, with the major physicochemical and ... -
Effects of temperature on behavior, growth, development and survival in young milkfish, Chanos chanos (Forskal)
(Elsevier, 1983)Effects of three temperature treatments on activity, feeding, growth, development and survival of young milkfish (Chanos chanos) were investigated. Low temperature (<22.6°C) and hypoxial condition (<1 ppm O2) decreased ... -
Effect of different diets on the ultrastructure of hepatocytes of Chanos chanos fry (Chanidae: Teleostei): An electron microscopic and morphometric analysis
(Springer-Verlag, 1983)The hepatocytes of milkfish fry offered different artificial diets (carbohydrate-, lipid-, protein-oriented) and live food (Artemia spp., Brachionus plicatilis) differ considerably both qualitatively and quantitatively as ... -
Effect of artificial diets on growth and survival of milkfish fry in fresh water
(Elsevier, 1983)Wild milkfish fry (mean weight = 15 mg) were reared in fresh water for 5 weeks using four artificial dry diets, Moina, or blended water hyacinth leaves as feed. The fry fed with artificial diets attained 83–95% mean survival ... -
Survival and some histological changes in Penaeus monodon Fabricius juveniles fed various carbohydrates
(Elsevier, 1983)Juveniles of P. monodon Fabricius (initial mean weight 1.76 g) were reared on semipurified diets containing 10 or 40% maltose, sucrose, dextrin, molasses, cassava starch, corn starch or sago palm starch for 6 weeks. Highest ... -
The effect of thyroxine on the larvae and fry of Sarotherodon niloticus L. (Tilapia nilotica)
(Elsevier, 1983)Effects of thyroxine (T4) (0.1 ppm; 0.3 ppm; 0.5 ppm) on Sarotherodon niloticus L. yolk sac larvae were studied after 4 weeks of treatment from hatching. T4 at 0.5 ppm accelerated yolk resorption but ... -
The effect of starvation and subsequent feeding on the hepatocytes of Chanos chanos (Forsskal) fingerlings and fry
(Academic Press, 1983)Excised liver sections of the milkfish, Chanos chanos, fry and fingerlings were studied by transmission electron microscopy. The hepatocytes underwent marked ultrastructural alterations in response to food deprivation of ... -
Supplement of various attractants to a practical diet for juvenile Penaeus monodon Fabricius
(Fisheries Research Society of the Philippines, 1983)Practical diets supplemented with krill meal (5%), earthworm meal (5%), glycine (2%), sucrose (5%) or mussel extract as an attractant were fed for eight weeks to juvenile Penaeus monodon. The major protein sources of the ... -
Traditional devices for capturing crabs used in the Philippines today
(Carcinological Society of Japan, 1983)The author intends to illustrate and describe the indigenous devices traditionally used to capture crabs including the constructions and the operational manners. Also the present writing is hoped to play a role in disseminating ... -
A further note to “fishing gear for prawn and shrimp used in the Philippines today”
(Carcinological Society of Japan, 1983)Motoh (1980) reported 9 and 13 kinds of shrimping gear for the fry and the adult respectively, of which most of them are indigenously used today in the Philippines. Howerver, druing the continued ecological survey of ... -
Gonadotropin profiles in serum of milkfish treated with salmon pituitary homogenate
(University of the Philippines Los Baños, 1983)Serum gonadotropin (GtH) levels were determined by radioimmunoassay (RIA) in adult regressed milkfish injected or implanted with various doses of salmon pituitary homogenate (SPH). Gonadotropin profiles of injected or ... -
