Qualitative and quantitative comparison of bacterial flora associated with hatchery-reared and wild-caught shrimp postlarvae
(ASIARESIST, 2005)
Because of high mortality recorded in pond-reared shrimps due to luminescent vibriosis infection, a study was conducted to determine if postlarvae (PLs) could be major sources of luminescent bacteria (LB). Batches of ...
Prawn nutrition, feed development and feeding techniques for grow-out and broodstock
(Philippine Council for Aquatic and Marine Research and Development, 1989)
Knowledge on nutritional requirements of prawn juveniles and broodstock are scanty. However, relatively more information is now available with regard to requirements of juveniles compared to that of broodstock.
Many ...
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 ...
Induction of sex inversion in juvenile grouper, Epinephelus malabaricus, (Bloch and Schneider) by bi-weekly injections of 17 alpha-methyltestosterone
(Society for the Study of Endocrinology, Metabolism and Reproduction, University of Hong Kong, 1989)
Groupers (Family Serranidae) are protogynous hermaphrodites. Natural sex inversion of different species occurs at 2-11 years of age . The scarcity of wild mature males and the length of time to change sex underline the ...
Photoperiod effects on feeding, food conversion, growth, and survival of abalone (Haliotis asinina Linne) during nursery rearing
(Phuket Marine Biological Center, 2001)
Juveniles of Haliotis asinina, 10 mm shell length were subjected to four photoperiodic regimes namely, 6L:18D, OL:24D, diffused 12:12D, and ambient light (12L:12D) serving as control. Juveniles were fed fresh seaweed, ...
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 ...
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, molting, food ingestion, and absorption in juvenile Macrobrachium rosebergii in relation to dissolved oxygen
(European Aquaculture Society, 1989)
Growth, molting, food ingestion, and absorption in juvenile Macrobrachium rosenbergii were evaluated at 2.5, 3.5, 5.0, and 7.7ppm dissolved oxygen (DO), 29°C, and 0.5°/oo salinity. DO levels were maintained by bubbling ...
Response of Penaeus monodon juveniles to aflatoxin B1 dietary contamination
(Asian Fisheries Society, 1994)
Effect of supplemental lecithin and lipid sources on the growth and survival of Penaeus monodon juveniles
(Asian Fisheries Society, 1986)
Penaeus monodon juveniles were reared in 60-liter fiberglass oval tanks in a flow-through seawater system for 8 weeks to determine the effect of lecithin and type of lipid on growth and survival. Nine isonitrogenous and ...
