The effect of different binders on the water stability of feeds for prawn
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
Corn starch, gelatin, sago palm starch, agar, and bread flour were tested for their binding capacity in pelleted diets for Penaeus monodon . Agar was found to be good binder, but it costs too much, while bread flour was ...
Toxicity of malachite green to the larvae of Penaeus monodon Fabricius
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
A study was undertaken examining the effect of malachite green on the development and survival of the zoeae, mysis and post-larvae of Penaeus monodon. Sensitivity varied with the different larval stages; the zoeae appeared ...
Survival rate of Penaeus monodon Fabricius larvae fed Chaetoceros sp. and bread yeast
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
An evaluation was made of the effects of Chaetoceros species, bread yeast and their combination on the survival of Penaeus monodon larvae. In general it was found that feeding with a combination of the 2 resulted in higher ...
Effect of different sex ratios of ablated wild-stock Penaeus monodon Fabricius on maturation, fecundity and hatching rates
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1979)
Preliminary histological study of the ovarian development of the giant tiger prawn, Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1978)
This study was undertaken to determine structural characteristics within the gonads which might serve as an index to age and longevity and furnish information on the frequency of spawning of an individual.
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 ...
