Spawner size and the biological components of the reproduction process in Penaeus monodon Fabricius.
(1986)The biological components of the reproduction process of Penaeus monodon spawners collected from the wild along Tigbauan-Guimbal coastal area, Philippines, were evaluated. Data were collected on wet body weight, eggs per ... -
Layout and design of aquaculture project: pen and cage systems
(ASEAN/UNDP/FAO Regional Small Scale Coastal Fisheries Development Project, 1986)Various floating cage and fishpen designs are employed to meet enclosure requirements of shrimp and milkfish brood-stock, and for rearing of other finfish at the lgang Substation of the SEAFDEC Aquaculture Department in ... -
Design and construction of a fishpen for an aquaculture-based social laboratory
(ASEAN/UNDP/FAO Regional Small Scale Coastal Fisheries Development Project, 1986)A pilot project for the pen culture of Tilapia nilotica and bighead carp in an irrigation canal was initiated in Barangay Cauayan, Pototan, Iloilo. The project, Cauayan Social Laboratory, involves cooperators from the ... -
Comparative performance of three propeller blades used for push pumps
(ASEAN/UNDP/FAO Regional Small Scale Coastal Fisheries Development Project, 1986)With the increasing trend to use pumps in aquaculture operations, tests were conducted on push pumps with three different propeller types. Type 21, a stainless two-bladed propeller where the blades were aligned together ... -
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 ... -
Pond liming and liming materials for brackishwater ponds
(ASEAN/UNDP/FAO Regional Small Scale Coastal Fisheries Development Project, 1986)Vital information aquaculturists need to know on lime are: (a) what lime to use; (b) why lime is used; (c) which form to apply; (d) how much to apply; and (e) when to apply. Experiments on the use of lime in ... -
Histopathology of chlorella-feeding in larval milkfish, Chanos chanos
(1986)Unicellular algae, particularly Chlorella, are widely used as starter feeds for marine finfish larvae. However, milk fish larvae when reared on Chlorella sp., suffered morality up to 100% within the first days of feeding ... -
The saltwater system at the Tigbauan Research Station of the Southeast Asian Fisheries Development Center, Aquaculture Department.
(ASEAN/UNDP/FAO Regional Small Scale Coastal Fisheries Development Project, 1986)Constructed in 1974, the present saltwater system of the SEAFDEC/AQD Tigbauan Research Station (TRS) consists of five pumps, two sump pits, a buffer, sedimentation and filtration treatment system (BSF), an intake pipe, and ... -
Intensification techniques in the extensive culture of Penaeus monodon
(Asian Fisheries Society, 1986)Traditional shrimp (Penaeus monodon) farming is characterized by low yields, 100-300 kg/ha/yr. To provide farmers with appropriate technology that can immediately improve pond yield with minimal investment, experiments ... -
Effect of supplemental lecithin and lipid sources on the growth and survival of Penaeus monodon juveniles
(Asian Fisheries Society, 1986)Penaeus monodon juveniles were reared in 60-liter fiberglass oval tanks in a flow-through seawater system for 8 weeks to determine the effect of lecithin and type of lipid on growth and survival. Nine isonitrogenous and ... -
Application of engineering scale-up principles in aquaculture
(ASEAN/UNDP/FAO Regional Small-Scale Coastal Fisheries Development Project, 1986)The effects of water movement or agitation on the biological performance of planktonic organisms under intensive culture have been rarely studied quantitatively. Stagnation or minimum values are considered important in the ... -
Integrated farming of broiler chickens with fish and shrimp in brackishwater ponds
(Asian Fisheries Society, 1986)An experiment on the integrated farming of broiler chickens with milkfish (Chanos chanos), tilapia (Oreochromis niloticus) and shrimp (Penaeus indicus) in brackishwater ponds was conducted in 1,000-m2 ponds of ... -
Efficiency of some cyanophytes as larval feed for silver carp (Hypophthalmichthys molitrix) and the culture of Spirulina platensis
(Asian Fisheries Society, 1986)Six-day old carp (Hypophthalmichthys molitix) fry (mean weight 3 mg) were stocked at 5/l in aquaria. These were fed with unialgal cultures of three species of blue-green algae, namely: Anabaena sp., Oscillatoria quadripunctulata ... -
Collection of naturally-spawned milkfish eggs in floating cages
(Asian Fisheries Society, 1986)Natural spawnings of milkfish from floating cages were obtained from different stocks of 5-7 year-old milkfish in 1980, 1981, 1983 and 1985. The maximum number of eggs collected in 1980, using a series of 1-m diameter ... -
The effect of diet on the reproductive performance of pond-reared Penaeus monodon Fabricius broodstock
; Primavera, Jurgenne
; ; (Asian Fisheries Society, 1986)
Three practical diets were tested for their effects on the reproductive performance, survival and larval quality of pond-reared Penaeus monodon. Diets A, B and C were formulated to contain the same basal components but ... -
An integrated semi-intensive shrimp and livestock system in the Philippines
(Asian Fisheries Society, 1986)The development of a shrimp (Penaeus monodon) production system integrated with livestock was undertaken at the Sycip Plantation Inc., Negros Oriental, Philippines, as a result of crop diversification efforts in the ... -
Effects of storage on the microbial quality of slipper oysters, Crassostrea iredalei
(Asian Fisheries Society, 1986)The effects of storage on the microbial quality of slipper oysters, Crassostrea iredalei, were examined. Oysters were stored at room temperature (24°C), under a blanket of ice (3-4 C), chilled (4-C) and frozen (-25°C) until ... -
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) ... -
Morphological development of the swimming and feeding apparatus in larval rabbitfish, Siganus guttatus.
(1986)The development of body parts for swimming and feeding in Siganus guttatus larvae was studied in samples reared in the laboratory at temperatures of 27.3-30 degree C. From the observations, the larval stage of S. guttatus ...
