Tolerance of Penaeus monodon eggs and larvae to fungicides against Lagenidium sp. and Haliphthoros philippinensis
(Elsevier, 1986)
The in vivo effect of mycostatic levels of fungicides against the fungi Lagenidium sp. and Haliphthoros philippinensis was tested on Penaeus monodon eggs and larvae. Hatching rate and survival of nauplii, zoeae, myses and ...
Viability of frozen algae used as food for larval penaeids
(Fisheries Research Society of the Philippines, 1981)
Freezing with added chemicals as flocculants and protectants as means of preserving stock cultures was tried with four species commonly used as larval food. The species were Chaetoceros calcitrans, Skeletonema costatum, ...
Linoleic (ω6) and linolenic (ω3) acids in the diet of fingerling milkfish (Chanos chanos Forsskal)
(Elsevier, 1988)
Feeding trials were conducted to determine the effects of linoleic acids on growth, survival, fatty acid composition and liver histology of milkfish. Five isocaloric semi-purified diets were formulated, either lipid-free ...
A comparative study of various extenders for milkfish, Chanos chanos (Forsskal), sperm preservation
(Elsevier, 1982)
Various extenders, containing potassium chloride, sodium chloride, glucose, sodium citrate, Ringer's solution, cow serum and milkfish serum were used to preserve milkfish (Chanos chanos) sperm at near-zero temperatures ...
The effects of Vibrio anguillarum extracellular products on Japanese eels
(Elsevier, 1989)
To test the effect of Vibrio anguillarum extracellular products (ECP) on Japanese eels (Anguilla japonica ), test fish were injected intramuscularly with ECP at a dose of 1 mg protein/100 g body weight of fish.At 3,6,12,24 ...
Yolk and oil globule utilization and developmental morphology of the digestive tract epithelium in larval rabbitfish, Siganus guttatus (Bloch)
(Elsevier, 1987)
The purpose of this study was to find out how yolk and oil globule absorption in Siganus guttatus proceed as the digestive tract develops, in order to determine the probable causes of early larval mortality. Yolk and oil ...
Year-round spawning and seed production of the rabbitfish, Siganus guttatus
(Elsevier, 1986)
A series of experiments on the spawning and larval rearing of Siganus guttatus was conducted during a 14-month period in 1984–1985. Spawning occurred every month throughout the year, without hormonal treatment, between the ...
Ion chromatography of inorganic anions in brine samples
(Oxford University Press, 1989)
An ion chromatographic method for separating and detecting anions in brine samples is described. Nitrite, bromide, nitrate, and sulfate ions in brine samples are well separated when chloride ion concentration in the sample ...
Osmotic and chloride regulation in the hemolymph of the tiger prawn Penaeus monodon during molting in various salinities
(Springer Verlag, 1987)
The effect of molting on osmotic and chloride concentrations in the blood of the prawn Penaeus monodon Fabricius (20±3 g) at various salinities was investigated. Prawns were obtained from ponds in Iloilo, Philippines, in ...
Studies on the causative organism of Oreochromis niloticus (Linnaeus) fry mortalities I. Primary isolation and pathogenicity experiments.
(Taylor & Francis, 1987)
Oreochromis niloticus fry reared in 50 L aquaria at a density of 1,000 fry manifested mortalities of 15% daily. Afflicted two-week old fry exhibited darker pigmentation, emaciation lesions, and surface swimming. Parasites ...
