Larval and early juvenile fishes associated with milkfish fry at Malandog, Hamtik, Antique
(Fisheries Research Society of the Philippines, 1983)
From 5 May 1981 to 7 November 1981 a total of 122,841 specimens of milkfish fry and early juvenile fishes was collected with the use of a milkfish fry sweeper. Of these, 66,361 or 54.02% consisted of early juvenile stages ...
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 ...
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 ...
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 ...
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 ...
Intestinal glucose transport in carnivorous and herbivorous marine fishes
(Springer Verlag, 1983)
The influx and transepithelial movements of glucose and their effects on the electrophysiology and Na transport in upper and lower intestines of the herbivorous surgeonfish, Acanthurus mata , and carnivorous eel, Gymnothorax ...
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 ...
Effect of varying dietary crude protein levels on spawning frequency and growth of Sarotherodon niloticus breeders
(Fisheries Research Society of the Philippines, 1983)
Four-month-old S. niloticus breeders were fed with dry pellets containing 20 to 50% crude protein in two separate experiments. Their frequency of spawning and their growth in length and weight were determined over a 16-week ...
