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 ...

Design, operation and economics of a small-scale hatchery for the larval rearing of sugpo, Penaeus monodon Fab.
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
One of the major problems in the mass production of sugpo is how to obtain a constant supply of fry. Since ultimately it is the private sector which should produce the sugpo fry to fill the needs of the industry, the ...

Development of a brood stock of the jumbo tiger prawn, Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1976)
The full-scale cultivation of sugpo, P. monodon Fabricius, could only be realized if there is an assurance of continuous supply of fry. Obviously, a steady supply will depend largely on the availability of spawners. In ...
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 ...
Freshwater fisheries expands program
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978-12)
The SEAFDEC Aquaculture Department Freshwater Fisheries Station, located at Binangonan, on the shores of Laguna Lake, has drafted a programme for expansion. These include the piloting of a fish feed mill and the establishment ...
SEAFDEC nursery pond system solves prawn fry survival problems
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978-11)
Prawn culture has been encouraged in the Philippines as an alternative to fish (bangus), since the former provides a higher income, better nutrition, and increased employment. The Aquaculture Department has made sugpo fry ...
