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 ... -
Bacteria associated with infection at hormone-implantation sites among milkfish, Chanos chanos (Forsskal), adults
(Blackwell Publishing, 1986)SEAFDEC Contribution No. 164. Paper presented at the Second International Warmwater Fish Conference at Laie, Hawaii, 5–8 February 1985. -
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 ... -
Larvae and juveniles of pempheridid fishes, Pempheris xanthoptera and P. japonica
(The Ichthyological Society of Japan, 1986)Larval developments of Pempheris xanthoptera and P. japonica were described on 31 (6.45–22.40 mm SL) and 5 (10.35–35.70 mm SL) specimens, respectively, with particular attention to cartilaginous development. Comparison ... -
Spawning behavior and early life history of the rabbitfish, Siganus guttatus, in the laboratory
(Elsevier, 1986)The spawning behavior and embryonic and larval development of Siganus guttatus are described from laboratory observations. Characteristic prespawning behavior began 4 h before actual spawning: the female touched the anal ... -
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 ... -
Effect of salinity on the osmotic, chloride, total protein and calcium concentrations in the hemolymph of the prawn Peneaus monodon (Fabricius)
(Elsevier, 1986)1. Osmolality and chloride concentrations in the hemolymph of Penaeus monodon became stable 1 day after molting in 32 ppt, while total protein and calcium concentrations remained stable throughout the molting cycle. When ... -
Digestibility in milkfish, Chanos chanos (Forsskal): Effects of protein source, fish size and salinity
(Elsevier, 1986)The true digestibility of casein, gelatin, fish meal, defatted soybean meal and Leucaena leucocephala leaf meal was measured in 60- and 175-g milkfish (Chanos chanos Forsskal) in fresh- and seawater. The diets contained ... -
Effects of salinity on egg development and hatching of Siganus guttatus
(University of San Carlos, 1986)Experiments were conducted to determine the tolerance of Siganus guttatus eggs to salinity changes. In the first run, the female was induced to spawn spontaneously by using human chorionic gonadotropin. The fertilized eggs ... -
Biological evaluation of three phytoplankton species (Chlorella sp., Tetraselmis sp., Isochrysis galbana) and two zooplankton species (Crassostrea iredalei, Brachionus plicatilis) as food for the first-feeding Siganus guttatus larvae
(University of San Carlos, 1986)First-feeding Siganus guttatus larvae were given different species of phytoplankton (Chlorella, Tetraselmis, Isochrysis) and zooplankton (oyster trochophores, Brachionus) or a combination of both on the first day when they ... -
Effect of stocking density and duration on stunting milkfish fingerlings in ponds
(Taylor & Francis, 1986)The paper discusses the effect of stocking density and holding periods in stunting milkfish fingerlings in brackishwater ponds using twelve units of 144m2 earthen ponds. With 15, 20, and 25 fingerlings/m2 ... -
