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 ... -
The mechanics of mass occurrence and recruitment strategy of milkfish Chanos chanos (Forsskal) fry in the Philippines
(Kagoshima University Research Center for the South Pacific, 1983)The daily and hourly catch of milkfish Chanos chanos (Forsskal) fry in the coast of Hamtic, Panay Island in the Philippines was recorded over a period of 16 weeks, and correlated with time, location, types of gear, and ... -
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 ... -
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 ... -
The quantitative dietary protein requirements of Penaeus monodon juveniles in a controlled environment
(Elsevier, 1983)Penaeus monodon juveniles (average weight = 1.32 g) were kept in individual 2 l perforated plastic containers, 10 of which were placed in each of the twenty-four 50 l rectangular wooden-glass aquaria supplied with seawater ... -
Seasonal variation in food and feeding of Penaeus monodon Fabricius (Decapoda, Natantia)
(E.J. Brill, 1982)A preliminary study on feeding habits of P. monodon F. (cf. Marte, 1980) indicated seasonal variations in feeding in this species. Similar observations have been reported for P. aztecus Ives and P. duorarum Burkenroad. The ... -
In vitro effect of fungicides on hyphal growth and sporogenesis of Lagenidium spp. isolated from Penaeus monodon larvae and Scylla serrata eggs.
(Blackwell, 1982)The sensitivity of Lagenidium spp. isolated from Penaeus monodon and Scylla serrata to 34 antimycotic compounds was determined. Mycostatic effects were evaluated from observations of chemicals on the development of vesicles, ... -
Gill lesions associated with acute exposure to ammonia.
(University of the Philippines, 1982)The histopathological effects of the 96 hr LC50 at 20.65 ppm NH3-N on the gills of milkfish fingerlings were examined qualitatively. Lesions observed were hypertrophy, hyperplasia, fusion of the ... -
Vertical diurnal migration of Daphnia cucculata and Eudiaptomus graciloides in eutrophic Frederiksborg Castle Lake, Denmark
(University of the Philippines at Los Baños, 1982)In euthrophic Frederiksborg Castle Lake, Berg & Nygaard were the first to study vertical migration. They obtained water samples at various time intervals over several days and concluded that the bulk of the population of ... -
Studies on the digestive proteases of the milkfish Chanos chanos
(Springer, 1982)The protease activity of crude extracts from various organs of the digestive tract of two groups of milkfish was determined. One group (Sample A) derived their food from ponds that had predominantly unicellular algae while ... -
Ascorbic acid sulfate sulfohydrolase (C2 sulfatase): the modulator of cellular levels of L-ascorbic acid in rainbow trout.
