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 ...
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 ...
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 ...
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 ...
The visual feeding threshold and action spectrum of northern anchovy (Engraulis mordax) larvae
(California Cooperative Oceanic Fisheries Investigations, 1983)
The visual feeding threshold and action spectrum of 10-15-mm northern anchovy larvae were determined, using as criterion the incidence of two or more rotifers in the guts of 50% of larvae tested under different spectral ...
Some histological observations on the opaque eyes of milkfish Chanos chanos Forskal
(Fisheries Research Society of the Philippines, 1983)
In a study on energy-protein requirements of milkfish fingerlings using semi-purified diets, several gross observations were made on individual milk-fish such as fin and tail rot, yellowish coloration of the abdomen, opacity ...
The effect of thyroxine on the larvae and fry of Sarotherodon niloticus L. (Tilapia nilotica)
(Elsevier, 1983)
Effects of thyroxine (T<sub>4</sub>) (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. T<sub>4</sub> at 0.5 ppm accelerated yolk resorption but ...
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 ...
