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 ...
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 ...
Studies on the chronic soft-shell syndrome in the tiger prawn, Penaeus monodon Fabricius, from brackishwater ponds
(Elsevier, 1986)
Prawn culture is becoming more widespread in the Philippines. In recent years, prawn production in brackishwater ponds has been adversely affected by a chronic soft-shell syndrome. A field survey of prawn ponds in the ...
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 ...
Early larval development of the seabass Lates calcarifer with emphasis on the transition of energy sources
(Japanese Society of Fisheries Science, 1986)
The early growth, yolk and oil globule resorption, early morphological and behavioral de-velopment, and initial feeding of hatchery-raised Lates calcarifer were studied. Based on the developmental events and the energy the ...
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 ...
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 ...
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 ...
An incidence of swimbladder stress syndrome in hatchery-reared sea bass (Lates calcarifer) larvae
(Elsevier, 1986)
This paper describes an incidence of swimbladder malfunction causing high positive buoyancy and mass mortality in 2-week-old sea bass (Lates calcarifer) larvae reared in an outdoor hatchery tank under conditions of high ...
