Bacterial exoskeletal lesions of the tiger prawn Penaeus monodon
(Asian Fisheries Society, 1990)
Tank- and pond-reared Penaeus monodon with exoskeletal lesions were examined. The incidence rate was up to 36% for broodstock in concrete tanks and to 20% for pond-reared prawns. The increase in disease incidence was related ...
Dietary manipulation to control the chronic soft-shell syndrome in tiger prawn, Penaeus monodon Fabricius.
(Asian Fisheries Society, 1990)
Penaeus monodon collected from brackishwater ponds in Iloilo, Philippines, were induced to become soft-shelled in the laboratory for 3-4 weeks. Eight isocaloric and isonitrogenous diets containing 0:0; 0:1; 1:0; 1:0.2; ...
Defatted soybean meal and Leucaena leaf meal as protein sources in diets for Penaeus monodon juveniles
(Asian Fisheries Society, 1990)
Penaeus monodon juveniles, mean weight 0.38 g, were fed 12 practical diets with 30, 20 or 16% Peruvian fish meal, 15 or 35% defatted soybean meal (DSM), 10% Leucaena leucocephala , leaf meal (LM), and 15% shrimp meal with ...

Mineral requirements of Penaeids
(Institut Francais de Recherche pour l'Exploitation de la Mer, 1990)
Marine shrimps absorb minerals from their aquatic environment aside from the minerals that come from the food they eat. Thus, the dietary requirement of shrimps for certain minerals will depend on the amounts and availability ...
Variation in the biochemical composition of Penaeus monodon tissues during the reproductive cycle.
(Bamidgeh, 1990)
The gonadosomatic index (GSI) and the hepatosomatic index (HSI) were determined for wild-caught, eyestalk ablated Penaeus monodon at 5 reproductive stages (I to V). Tissues of the muscle, ovary and hepatopancreas in each ...
Supplemental feeding of Penaeus monodon juveniles with diets containing various levels of defatted soybean meal
(Elsevier, 1990)
Varying levels of defattedsoybeanmeal DSM (15, 25, 35, 45 and 55%) in supplementaldiets with approximately 40% crude protein and 10% crude fat were fed to tiger prawn juveniles in 1 m×1 m×1 m net cages set on the bottom ...
Studies on the chemical control of luminous bacteria Vibrio harveyi and V. splendidus isolated from diseased Penaeus monodon larvae and rearing water
(Inter Research, 1990)
The minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) of 24 drugs for luminous bacteria Vibrio harveyi and V. splendidus were determined. Only chloramphenicol, sodium nifurstyrenate ...
Isolation and characterization of vitellin from the ovary of Penaeus monodon
(International Society of Invertebrate Reproduction and Development, 1990)
Female-specific protein (FSP, vitellogenin) in Penaeus monodon hemolymph and its related ovarian protein (vitellin, lipovitellin) were identified and characterized using electrophoretical and immunological procedures. The ...
Organic pollution resulting from excess feed and metabolite build-up: Effect on Penaeus monodon postlarvae
(Elsevier, 1990)
Penaeus monodon postlarvae, PL, with mean weight and mean total length of 0.57 mg and 6.5 mm respectively, were stocked in aerated aquaria at 20 litre<sup>−1</sup> of seawater. They were fed minced shrimp meat at rates of ...
Occurrence of luminous bacterial disease of Penaeus monodon larvae in the Philippines
(Elsevier, 1990)
Larval mortalities associated with luminescence have been observed in epizootic proportions in black tiger prawn (Penaeus monodon) hatcheries in Panay Island, Philippines. Luminescent vibrios, identified as Vibrio harveyi ...
