Tolerance of Penaeus monodon larvae to cupric sulfate added in bath
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Copper is used to deter the growth of bacterial, fungal and protozoan disease organism in fishes. Zoeae (Z<sub>1</sub>), myses (M<sub>1</sub>) and postlarvae (P<sub>1</sub>) were exposed to copper sulfate at concentrations ...
Preliminary chemical and physical evaluation of some formulated feeds for P. monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
The culture of Penaeus monodon has explicitly defined the need for diet formulations or supplementary feeds that would promote optimum growth and survival of the animal. A total of 28 feed combinations were developed for ...
The effect of various protein levels on the growth and survival rates of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Postlarvae of tiger prawns, P. monodon , were fed with various protein levels of 0; 30; 40 and 50%, fish meal and rice bran were combined and pelletized for 16 wks. Prawns used had an average mean length of 1.2 mm and an ...
Effects of furanace on Brachionus
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Tiger prawn P.monodon) larvae utilize Brachionus a rotifer, as food in the Zoea 3 and mysis stages when they change from an herbivorous to an omnivorous diet. The present work aims to show the effects of furanace on the ...
Preliminary biological evaluation of some formulated feeds for P. monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Rice bran is widely used by fish farmers as supplementary feed while soybean cake is used both as feed and as fertilizer in fishponds. Both fish meal and shrimp head have been found acceptable as feed ingredients. However, ...
Amino acid analysis of P. monodon muscle
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Figures for the amino acid composition of Penaeus monodon, are tabulated, and compared to those for white tuna meat.
Bacteria from seawater used in Penaeus monodon larval cultures
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Bacteria in the seawater used in P. monodon hatchery operations were isolated on Bachmann's agar. The total plate counts in 25 isolations ranged from 1.0 - 5.0 x 10<sup>2</sup> to 5.1 -10.0 x 10<sup>5</sup> cells per ml. ...
Reduction in Chaetoceros populations by furanace
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
One of the most promising prophylactic agents being tested to control Penaeus monodon larval diseases is furanace (6-hydroxymethyl-2 2(5-nitro-2-furyl) vinyl pyridine). To evaluate further its suitability as a chemotherapeutic ...
Organic pollution in culture water resulting from excess feed and metabolite buildup
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
Penaeus monodon postlarvae were subjected to increasing feed concentrations and their growth and survival rates were recorded. Measurements were made of dissolved organic matter, and ammonia and nitrite-nitrogen concentrations. ...
The biology and control of Caligus sp., an ectoparasite of the adult milkfish Chanos chanos Forskal
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
One unidentified species of copepod belonging to the genus Caligus of the family Caligidae was found to infest the adult milkfish broodstock. To control the parasites infesting the adult milkfish, tests were made using the ...
