Preserved algae as food for Penaeus monodon larvae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Uni-algal cultures of C. calcitrans, S. costatum, T. chui and Isochrysis sp. obtained from the laboratory were harvested. The harvest, preserved by either freezing or sun-drying, was fed to the larvae of P. monodon . Among ...
A simple method of tagging prawns
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1977)
The recognition of individual animals is crucial to many aspects of research. Prawns (Penaeus monodon) present unique difficulties in this respect since they molt regularly. Thus, almost all tagging and marking methods ...
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. ...
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 ...
Experiment on larval rearing of Penaeus monodon fed with cultured diatom Chaetoceros calcitran and fermented vegetable trash
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
A brief account is given of experiments undertaken rearing Penaeus monodon larvae fed on diatom (Chaetoceros calcitran) and fermented vegetable trash, which included fruits and their peels, vegetables and rice. The possible ...
