Light color and ovarian maturation in unablated and ablated giant tiger prawn Penaeus monodon (Fabricius)
(Elsevier, 1992)
The effect of light color (green, blue and white fluorescent lights, with natural light as a control) on maturation in intact and eyestalk-ablated Penaeus monodon was tested in 12-m<sup>3</sup> broodstock tanks. Size and ...
Chlorination of seawater used for shrimp culture
(SIAMB, 1990)
Chlorination of sand-filtered and microfiltered seawater for 24 hours significantly reduced the initial bacterial load from 10<sup>5</sup> to 10<sup>0</sup> - 10<sup>1</sup> colony forming units (cfu) per ml. The total ...
Changes in shrimp feed quality and effects on growth and survival of Penaeus monodon juveniles
(Elsevier, 1997)
Five practical shrimp diets were formulated to contain 1, 10, 20, 50, and 100 g tetraethoxypropane (TEP) kg<sup>−1</sup> diet. A diet with no added TEP served as the control. Diets were fed to Penaeus monodon (average ...
Nature's subsidies to shrimp and salmon farming
(American Association for the Advancement of Science, 1998)
Although many fisheries stocks have declined precipitously throughout the world, fish farming--and especially shrimp and salmon farming--has boomed. The increasingly large scale of these enterprises is now having unforeseen ...
Mangroves and brackishwater pond culture in the Philippines
(Springer Verlag, 1995)
Around 50% of mangrove loss in the Philippines can be traced to brackishwater pond construction. The decrease in mangroves from 450 000 ha in 1920 to 132 500 ha in 1990 has been accompanied by expansion of culture ponds ...
Requirements of juvenile marine shrimp, Penaeus monodon (Fabricius) for lysine and arginine
(Elsevier, 1998)
Feeding experiments were conducted using amino acid test diets to determine the dietary requirements of juvenile Penaeus monodon for lysine and arginine. Two sets of the test diets were prepared. The natural protein was ...
The growth, survival and production of shrimp (Penaeus monodon) cultured with green mussel (Perna viridis) in semi-intensive ponds
(University of Philippines in the Visayas, 1997)
The culture of tiger shrimps (Penaeus monodon) with and without green mussels (Perna viridis) was compared in terms of animal growth, survival, production, and pond water quality. Tiger shrimps (2.6 g) were stocked at ...
Methionine requirement of juvenile tiger shrimp Penaeus monodon Fabricius
(Elsevier, 1996)
An 8-week feeding trial was conducted to determine the dietary requirement of postlarval Penaeus monodon for the sulfur-containing amino acid methionine. Shrimp postlarvae (mean weight 21 ± 0.3 mg) were reared in 40-1 ...
Economics of microalgae (Chaetoceros calcitrans) production using the multi-step method in the Philippines
(Elsevier, 1993)
The use of live microalgae for food during the early stages of the life cycle of shrimp larvae is considered essential. The microalga Chaetoceros calcitrans was mass produced at the Aquaculture Department of the Southeast ...
Isolation of Vibrio spp. from Penaeus monodon (Fabricius) with red disease syndrome
(Elsevier, 1997)
From January 1990 to June 1993, 59% of the total juvenile to adult shrimp Penaeus monodon submitted for diagnosis at the Fish Health Section of the Aquaculture Department, Southeast Asian Fisheries Development Center, ...
