Effect of pH and ammonia on survival and growth of the early larval stages of Penaeus monodon Fabricius
(Elsevier, 1994)
Lethal toxicity tests of ammonia at different pH levels (7, 7.5, 8, and 8.5) and its effect on survival and growth of the early larval stages of Penaeus monodon were determined. An increase in ammonia toxicity when the ...
Bacterial flora in the hepatopancreas of pond-reared Penaeus monodon juveniles with luminous vibriosis
(Elsevier, 1998)
Quantification and characterization of bacterial flora in the hepatopancreas (hp) of pond-reared Penaeus monodon juveniles affected with luminous bacteria were conducted in 1994 and 1995. Shrimp samples were taken from 23 ...
Valine requirement of postlarval tiger shrimp, Penaeus monodon Fabricius
(Wiley-Blackwell, 1996)
The valine requirement of juvenile tiger shrimp, Penaeus monodon Fabricius, was determined. Shrimp postlarvae, PL20, with a mean weight of 14 mg, were randomly distributed in 36 oval 40-L capacity fibreglass tanks at 10 ...
Low-cost feed for Penaeus monodon reared in tanks and under semi-intensive and intensive conditions in brackishwater ponds
(Elsevier, 1997)
Experimental diets for juvenile Penaeus monodon were formulated incorporating inexpensive indigenous raw materials. Local fish meal and cowpea meal were tested as replacements for imported protein sources and the diets did ...
Use of seaweed meals from Kappaphycus alvarezii and Gracilaria heteroclada as binders in diets for juvenile shrimp Penaeus monodon
(Elsevier, 1996)
Two seaweed meals were tested as binders in shrimp diets. In the first study, Kappaphycus alvarezii or Gracilaria heteroclada in dry ground form were added to an isonitrogenous diet at 3, 5, 7 or 10%. The basal diet had ...
Chicken manure, rice hulls, and sugar-mill wastes as potential organic fertilizers in shrimp (Penaeus monodon Fabricius) ponds
(Elsevier, 1992)
Shrimp (Penaeus monodon Fabricius) were cultured (3000 juveniles/ha) in 50-m<sup>2</sup> earthen ponds fertilized with composted agricultural and industrial wastes at a basal application rate of 2 ton/ha. The following ...
Effect of a diet lacking in vitamin and mineral supplements on growth and survival of Penaeus monodon juveniles in a modified extensive culture system
(Elsevier, 1995)
Penaeus monodon postlarvae (mean weight 6 mg) were reared in 330 m<sup>2</sup> earthen ponds for 120 days at a stocking density of 7.5 m<sup>−2</sup>, following a modified extensive culture system where natural food organisms ...
A practical method of extracting mimosine from ipil-ipil, Leucaena leucocephala, leaves and its effect on survival and growth of Penaeus monodon juveniles
(Society of Israeli Aquaculture and Marine Biotechnology, 1992)
Soaking fresh ipil-ipil, Leucaena leucocephala, leaves in tap water (1:1, v/v; or 50 g in 500 ml) for 30-48 hours with a water change after 24 hours extract atleast 90% of its mimosine, a toxic lysine derivative. This ...
Ovarian changes and female-specific protein levels during sexual maturation of the white shrimp Penaeus indicus
(Society of Israeli Aquaculture and Marine Biotechnology, 1992)
The histological changes in the ovary and female-specific protein levels in the hemolymph during sexual maturation of Penaeus indicus were determined. Ovarian maturation was classified into four stages: immature stage, ...
Growth performance of Penaeus monodon in lablab, lumut, and digman ponds under various farm practices
(Taylor & Francis, 1990)
The influence of lablab, lumut (filamentous algae), and digmaan (Najas graminea) on the growth of prawns as associates of natural food biomass in brackishwater ponds was investigated. Ponds, each grown with the above ...
