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 ...
Spontaneous maturation and spawning of milkfish in floating net cages
(Elsevier, 1986)
Milkfish (Chanos chanos Forsskal) reared from wild-caught fry and from hatchery-bred fry matured at 3.5-5.5 years (2.3-4.9 kg). Maturation and spawning of the hatcherybred fish marks the first time the milkfish life-cycle ...
Acetes as prime food for Penaeus monodon larvae
(Asian Fisheries Society, 1986)
This paper presents research attempts to develop a suitable artificial diet for shrimp larvae with locally-available materials. Larval rearing experiments using finely ground Acetes tissues conducted under various climatic ...
Use of ferrocement as secondary gate of fishponds.
(ASEAN/UNDP/FAO Regional Small Scale Coastal Fisheries Development Project, 1986)
Ferrocement was first used in the Department in fabrication of broodstock and hatchery tanks for shrimp. In 1981, the Capital Outlay Project at Leganes called for the design and construction of 210 gates, consisting of 2 ...
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 ...
Disease investigation of transported Chanos chanos stocked in Laguna Lake, Philippines
(Asian Fisheries Society, 1986)
Milkfish,Chanos chanos fingerlings transported by boat (petuya) for seven to eight hours were observed for stress-inducing factors during transport, daily for 10 days after stocking in pens in Laguna Lake, Philippines. ...
Antibiotic uptake of the giant freshwater prawn Macrobrachium rosenbergii by the osmotic infiltration technique
(Asian Fisheries Society, 1986)
Erythromycin and oxytetracycline uptake by the giant freshwater prawn, Macrobrachium rosenbergii , was evaluated by the two-step osmotic infiltration technique. Test prawns were immersed in 7.5% NaCl conditioning (hyperosmotic) ...
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 ...
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 ...
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 ...
