Studies on the sources of luminescent Vibrio harveyi in Penaeus monodon hatcheries
(Asian Fisheries Society, Fish Health Section, 1992)
One of the major problems in the otherwise highly successful Penaeus monodon hatchery industry in the Philippines is the occurrence of luminescent bacterial disease due to Vibrio harveyi. The possible sources of the bacteria ...
Urease activity in soybean meal: effect on its nutritional quality and on growth and survival of Penaeus monodon juveniles.
(International Foundation for Science, 1998)
Based on the results of a survey conducted on the urease activity (UA) in commercial shrimp feed containing soybean meal (SBM) (0.00-29. 70 ppm UA), a study was carried out to determine the effects of different heat ...
Growth and external reproductive parameters in pond-reared Penaeus monodon
(Marine Science Institute, University of the Philippines, 1994)
Pond-reared Penaeus monodon males and females were sampled regularly over a 4 month period of length and weight measurments to the body and external reproductive organs; joining of the petasmata and the presence of sperm ...
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 ...
Changes in the steroid hormone and vitellogenin levels during the gametogenic cycle of the giant tiger shrimp, Penaeus monodon
(Elsevier, 1994)
The levels of estradiol-17β, and progesterone in the hemolymph, ovaries and hepatopancreas, in relation to the vitellogenin levels of captive female Penaeus monodon, were determined during the gametogenic cycle. Estradiol ...
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 ...
Response of Penaeus monodon juveniles to aflatoxin B1 dietary contamination
(Asian Fisheries Society, 1994)
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 ...
Occurrence and pathology of Penaeus monodon baculovirus infection in hatcheries and ponds in the Philippines
(Society of Israeli Aquaculture and Marine Biotechnology, 1991)
Samples from Penaeus monodon hatcheries (2-3 day old larvae or Zoea 1 to 34 day old post larvae or PL<sub>34</sub>) and ponds (15 to 159 days old in the pond) were histologically examined for the presence of eosinophilic ...
Accumulation and excretion of metal granules in the prawn, Penaeus monodon, exposed to water-borne copper, lead, iron and calcium
(Elsevier, 1994)
Juveniles of the giant tiger prawn, Penaeus monodon, were exposed for 10 days to 1 mg/l copper, lead, iron or calcium in order to investigate the formation and accumulation of metal granules in major soft tissues as well ...
