Breeding and larval rearing of the rabbitfish, Siganus guttatus (Bloch)
Juario, Jesus V.; Duray, Marietta N.; Duray, Victoriano M.; Nacario, Jonathan F.; Almendras, Jesus Manolo E. (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 ... -
Early effects of nutritional stress on the liver of milkfish, Chanos chanos (Forsskal), and on the hepatopancreas of the tiger prawn, Penaeus monodon (Fabricius)
Storch, Volker; Juario, Jesus V.; Pascual, Felicitas P. (Elsevier, 1984)After periods of food deprivation and subsequent feeding, hepatocytes of Chanos chanos fry and R-cells of Penaeus monodon juveniles were investigated by means of transmission electron microscope. They clearly reflect the ... -
Effect of different diets on the ultrastructure of hepatocytes of Chanos chanos fry (Chanidae: Teleostei): An electron microscopic and morphometric analysis
Storch, Volker; Stählin, W.; Juario, Jesus V. (Springer-Verlag, 1983)The hepatocytes of milkfish fry offered different artificial diets (carbohydrate-, lipid-, protein-oriented) and live food (Artemia spp., Brachionus plicatilis) differ considerably both qualitatively and quantitatively as ... -
The effect of starvation and subsequent feeding on the hepatocytes of Chanos chanos (Forsskal) fingerlings and fry
Storch, Volker; Juario, Jesus V. (Academic Press, 1983)Excised liver sections of the milkfish, Chanos chanos, fry and fingerlings were studied by transmission electron microscopy. The hepatocytes underwent marked ultrastructural alterations in response to food deprivation of ... -
Effect of thyroxine on growth and development in post-yolk-sac larvae of milkfish, Chanos chanos
Lam, Tom J.; Juario, Jesus V.; Banno, Jessie E. (Elsevier, 1985)Post-yolk-sac larvae of milkfish, Chanos chanos (commonly referred to as “fry”) were collected along the shore in the Philippines. Treatment of these long, slender and transparent larvae with L-thyroxine-sodium (Eltroxin, ... -
Effects of Chlorella-feeding on larval milkfish, Chanos chanos, as evidenced by histological monitoring
Segner, Helmut; Burkhardt, Patricia; Avila, Enrique M.; Storch, Volker; Juario, Jesus V. (Elsevier, 1987)Milkfish, Chanos chanos, larvae were found to suffer 100% mortality within 6 days of feeding when reared on Chlorella sp. According to the liver ultrastructure, Chlorella-fed fish underwent starvation. Likewise, no signs ... -
Effects of exogenous hormone injections on milt consistency in newly caught, wild milkfish
Juario, Jesus V.; Quinitio, Gerald F.; Banno, Jessie E.; Natividad, Marietta R. (University of the Philippines at Los Baños, 1980)The study was conducted to study the effects of single injections of Human Chorionic Gonadotropin (HCG) (Ayerst Laboratories, Inc) and Durandron Forte 250, a long-acting androgen preparation (N.V. Organon Oss, Holland), ... -
Histological observations on the rearing of milkfish, Chanos chanos, fry using different diets
Segner, Helmut; Juario, Jesus V. (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 ... -
Histopathology of chlorella-feeding in larval milkfish, Chanos chanos
Segner, Helmut; Burkhardt, Patricia; Avila, Enrique M.; Storch, Volker; Juario, Jesus V. (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 ... -
Induced breeding and larval rearing experiments with milkfish Chanos chanos (Forskal) in the Philippines
Juario, Jesus V.; Duray, Marietta N.; Duray, Victoriano M.; Nacario, Jonathan F.; Almendras, Jesus Manolo E. (Elsevier, 1984)Salmon pituitary homogenate was used alone or in combination with human chorionic gonadotropin, to induce spawing in captive and wild adult milkfish at ambient temperature (26–30°C) and salinity of 34%.. Healthy or slightly ... -
Induced spawning of sea bass, Lates calcarifer, and rabbitfish, Siganus guttatus, after implantation of pelleted LHRH analogue
Harvey, B.; Nacario, Jonathan F.; Crim, Lawrence W.; Juario, Jesus V.; Marte, Clarissa L. (Elsevier, 1985)Captive Lates calcarifer broodstock at Tigbauan, Iloilo (Philippines) were implanted with cholesterol-based pellets of the LHRH analogue D-Trp6-desGly10-LHRH ethylamide or D-hArg(Et2)6, ... -
Influence of nutrition on the hepatocytes of Chanos chanos (Chanidae: Teleostei)
Storch, Volker; Segner, Helmut; Juario, Jesus V.; Duray, Marietta N. (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 ... -
