Dietary requirements of rainbow trout for tryptophan, lysine and arginine determined by growth and biochemical measurements
(Springer Verlag, 1986)Three separate studies were performed to determine the dietary requirements of rainbow troutSalmo gairdneri for tryptophan (Trp), lysine (Lys) and arginine (Arg) from both growth and biochemical data. The growth studies ... -
Leucaena leucocephala leaves in formulated feed for Penaeus monodon: a concrete example of the application of histology in nutrition research
(Elsevier, 1986)Penaeus monodon postlarvae were fed with formulated diets containing either soaked or unsoaked Leucaena leaves. A similarly prepared feed with soybean in place of Leucaena was used for comparison. Results were analysed by ... -
Duration of feeding and indirect selection for growth of tilapia
(Elsevier, 1986)Duration of spontaneous feeding was observed at three times each day in a laboratory population of nine juvenile tilapia (Oreochromis mossambicus). Growth of the fish was measured as change in length and weight, and also ... -
Early development of Crassostrea iredalei (Faustino, 1932) (Bivalvia: Ostreidae), with notes on the structure of the larval hinge
(California Malacozoological Society, Inc., 1986)Larvae of the oyster Crassostrea iredalei were reared in the laboratory from eggs through settlement. The oysters were induced to spawn by increasing the temperature by 5-10°C and sometimes by adding stripped oyster sperm ... -
The in vitro effects of cyclic nucleotides, cyanoketone, and cycloheximide on the production of estradiol-17β by vitellogenic ovarian follicles of goldfish (Carassius auratus)
(Academic Press, 1986)The effects of human chorionic gonadotropin (HCG), forskolin, cyclic nucleotides, the phosphodiesterase inhibitors IBMX and theophylline, cyanoketone, and cycloheximide on the production of estradiol-17β by isolated ovarian ... -
Early development of fin-supports and fin-rays in the milkfish Chanos chanos
(The Ichthyological Society of Japan, 1986)Development of fin-supports and fin-rays was observed in larval and juvenileChanos chanos, Chondrification of the caudal complex started at 4.70 mm SL. Ossification of the caudal elements started at 7.80 mm SL and was ... -
Harvesting techniques for Nile tilapia fingerlings
(Fisheries Research Society of the Philippines, 1986)The experiment was conducted in nine-320m2 - freshwater ponds to evaluate various techniques of harvesting tilapia fry. Three treatments with three replicates each were used: harvesting by seining the fry ... -
Polyculture of bighead carp, common carp and Nile tilapia in cages in Laguna lake
(Fisheries Research Society of the Philippines, 1986)Increasing fish production through polyculture was clearly demonstrated to the fishfarmers in Laguna lake. The rearing of different species of fish of proper number and species combinations had resulted to the efficient ... -
Histological observations on the rearing of milkfish, Chanos chanos, fry using different diets
(Blackwell Publishing, 1986)Six different diets, commonly used in the Philippines for rearing milkfish, Chanos chanos, try, were tested by means of growth, survival and histology. These diets included: a) live food (Artemia nauplii); b) two different ... -
An evaluation of formulated diets for Nile tilapia fingerlings
(Fisheries Research Society of the Philippines, 1986)Nine practical diets were formulated and prepared as dry pellet crumbles. These were fed to two batches of Nile tilapia fingerlings (0.753g initial mean body weigt for trial I, and 0.961g for trial II) at 10% of fish biomass ... -
Specific amino acid-free semi-purified diets for Penaeus monodon juveniles
(Kagoshima University Research Center for the South Pacific, 1986)To determine the effects of deficiency of individual amino acids believed to be essential to Penaeus monodon juveniles, a 28-day feeding experiment was carried out with P. monodon postlarvae. P. monodon postlarvae ... -
Tilapia (T. nilotica) and Azolla (A. pinnata) cage farming in Laguna Lake
(Fisheries Research Society of the Philippines, 1986)Four batches of Azolla were grown in cages in Laguna lake between 1981 to 1983. Percent increase in weight per day ranged from 35% (Feb. 24 - March 2, 1981) to 5% (May 8 - May 12, 1983.) Best growth was attained during the ... -
Feed preference of milkfish (Chanos chanos Forsskal) fry given different algal species as natural feed
(Elsevier, 1986)Acclimated milkfish fry (mean wet weight, 6.0 mg) were fed with unialgal cultures of five species of freshwater algae: Oscillatoria quadripunctulata, Chroococcus dispersus, Navicula notha, Euglena elongata and Chlorella ... -
Isolation and cultivation of Anabaena sp. from organic media after sterilization
(University of the Philippines at Los Baños, 1986)A species of Anabaena was isolated from the fronds of Azolla pinnata by combining the chopped fronds of the Azolla extract with either lake water or an organic medium (duck manure alone or combined with banana stalk) and ... -
Shift in steroidogenesis in the ovarian follicles of the goldfish (Carassius auratus) during gonadotropin-induced oocyte maturation
(Japanese Society of Developmental Biologists, 1986)Both partially purified chum salmon gonadotropin and 17α-hydroxyprogesterone stimulated in vitro production of testosterone by postvitellogenic follicles of goldfish (Carassius auratus). Chum salmon gonadotropin further ... -
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 ... -

Induced maturation and spawning of milkfish, Chanos chanos Forsskal, by hormone implantation
(Elsevier, 1986)The milkfish, Chanos chanos Forsskal, does not reach gonadal maturity easily in captivity. In an attempt to induce maturation, exogenous hormones, LHRH-A and 17α-methyl-testosterone, were implanted into adult milkfish ... -
