Seaweed research at SEAFDEC Aquaculture Department
(Seaweed Industry Association of the Philippines, 2003)
Seaweed research at the Aquaculture Department of SEAFDEC focuses mainly on 2 genera of agarophytes (Gracilaria and Gracilariopsis) and carrageenophytes (Eucheuma and Kappaphycus).
From 1988 to 1998, research works were ...
Computer-based resources for aquatic animal health
(Fish Health Section, Asian Fisheries Society, 2002)
A brief review of computer-based resources for aquatic animal health is presented, with emphasis on information sources likely to be of interest to scientists, diagnosticians, and university instructors working in the Asian ...
Quorum sensing and its potential application to vibriosis
(Fish Health Section, Asian Fisheries Society, 2002)
Quorum sensing is a gene regulatory mechanism by which certain pathogenic and symbiotic bacteria respond to population density and host association. By mediating the ability of bacteria such as Vibrio harveyi to infect ...
Identification and characterization of Vibrio bacteria isolated from fish and shellfish in Vietnam
(Fish Health Section, Asian Fisheries Society, 2002)
A taxonomic relationship of thirty one Vietnamese bacterial isolates from different fish and shellfish together with twenty two reference strains was investigated by Euclidean distance with unweighted average linkage ...
Growth promotion and enhancement of vibriosis resistance in penaeid shrimp after oral administration of lactic acid bacteria and marine bacteria
(Fish Health Section, Asian Fisheries Society, 2002)
Vibriosis is one of the most serious problems in the shrimp culture industry worldwide. Antibiotic treatment is becoming less and less effective, as new strains of pathogens evolve, which are resistant to commonly used ...
Genetic evidence for a unique taxonomic position of white spot syndrome virus of shrimp: Genus Whispovirus
(Fish Health Section, Asian Fisheries Society, 2002)
White spot syndrome virus (WSSV) is a relatively new agent causing a zoonotic disease in shrimp. Taxonomically this virus is presently an orphaned, floating virus species. WSSV has a unique virion morphology, genome ...
Prevalence of yellow head virus in cultured black tiger shrimp (Penaeus monodon Fabricius) from selected shrimp farms in the Philippines
(Fish Health Section, Asian Fisheries Society, 2002)
The prevalence and geographic distribution of Yellow head virus (YHV) in cultured Penaeus monodon in the Philippines was documented by Western blot assay. Fifty-three out of 219 samples (24.2%) were found to be positive ...
Effects of Artemia enriched with L-ascorbyl dipotassium-2-sulfate dihydrate on stress tolerance and disease resistance of Penaeus monodon postlarvae
(Fish Health Section, Asian Fisheries Society, 2002)
Penaeus monodon postlarvae (stage 10) were reared with Artemia nauplii enriched with 50,100 and 150 mg/l (ppm) of L-ascorbyl-dipotassium-2- sulfate dihydrate for 5 days. Postlarvae in the control group were given non-enriched ...
Alkalinity control in ozonated shrimp pond water
(Fish Health Section, Asian Fisheries Society, 2002)
The use of ozone for aquaculture has been shown to be effective, not only for disinfection of pathogenic bacteria and viruses, but also for removal of toxic ammonia, nitrite and hydrogen sulfide. However, ozonation of ...
Evaluation of the susceptibility of the shrimp Litopenaeus vannamei to vibriosis when exposed to agriculture pesticides
(Fish Health Section, Asian Fisheries Society, 2002)
Due to increasing stringency of environmental regulations, agricultural production systems have switched from persistent pesticides to products which degrade more rapidly. In spite of that, new pesticide products can affect ...
