Breeding and larval rearing of the rabbitfish, Siganus guttatus (Bloch)
(Elsevier, 1985)
Females of Siganus guttatus reared to sexual maturity in canvas tanks were induced to spawn by using human chorionic gonadotropin (HCG, Ayerst) at 500 IU/fish or about 2 IU/g body weight. The amount of HCG used depended ...
Artificial diets for milkfish, Chanos chanos (Forsskal), fry reared in seawater
(Elsevier, 1988)
Milkfish fry obtained from the wild (0.009 g body weight, 10 mm total length) were stocked at 200 individuals in each of 18 fiberglass tanks containing 30 l of filtered aerated seawater. Mean salinity and temperature were ...
Growth and mid-gut cells profile of Penaeus monodon juveniles fed water-soluble-vitamin deficient diets
(Elsevier, 1989)
Growth and changes in the mid-gut cell morphology of Penaeus monodon juveniles were evaluated after feeding for 35 days with semi-purified diets deficient in water-soluble vitamins. Diets were prepared by deleting one ...
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 ...
In vitro effect of fungicides on hyphal growth and sporogenesis of Lagenidium spp. isolated from Penaeus monodon larvae and Scylla serrata eggs.
(Blackwell, 1982)
The sensitivity of Lagenidium spp. isolated from Penaeus monodon and Scylla serrata to 34 antimycotic compounds was determined. Mycostatic effects were evaluated from observations of chemicals on the development of vesicles, ...
Influence of nutrition on the hepatocytes of Chanos chanos (Chanidae: Teleostei)
(Elsevier, 1984)
The hepatocytes of milkfish (C. chanos) fry and fingerlings offered a variety of diets differ considerably as was shown by means of transmission electron microscopy. For fry it was shown that a 7 day starvation period ...
Histopathology of microsporidian infection in white prawn, Penaeus merguiensis de Man, 1888.
(University of the Philippines, 1982)
Different stages of the white prawn, Penaeus merguiensis de Man, were examined for microsporidian infection. The parasite was found only in adult female prawns exhibiting white instead of the normal olive-green ovaries. ...
Histopathology of the chronic soft-shell syndrome in the tiger prawn Penaeus monodon
(Inter Research, 1987)
One of the disease problems that affect the production of tiger prawn Penaeus monodon Fabricius in brackish-water ponds is the chronic soft-shell syndrome, a condition in which the prawn shell is persistently soft for ...
Transition from endogenous to exogenous nutrition sources in larval rabbitfish Siganus guttatus
(Japanese Society of Fisheries Science, 1988)
The early larval development of Siganus guttatus was studied with emphasis on the transition from endogenous to exogenous feeding. Three rearing trials were conducted as follows: 1) rearing in a 5 ton concrete tank at ...
Seasonal variation in food and feeding of Penaeus monodon Fabricius (Decapoda, Natantia)
(E.J. Brill, 1982)
A preliminary study on feeding habits of P. monodon F. (cf. Marte, 1980) indicated seasonal variations in feeding in this species. Similar observations have been reported for P. aztecus Ives and P. duorarum Burkenroad. The ...
