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 ...
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 ...
Histopathology of a novel melanized lesion in the branchiostegite of cultured penaeid shrimps
(Fish Health Section, Asian Fisheries Society, 2002)
During routine investigations for white spot syndrome virus (WSSV) in shrimp farms of Kundapur in the West Coast of India, a novel melanized proliferative lesion was observed in the branchiostegite of Penaeus monodon and ...
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 ...
Epizootic ulcerative syndrome of fishes: rhabdovirus infection and EUS induction experiments in snakehead fish
(Fish Health Section, Asian Fisheries Society, 2002)
Rhabdoviral agents have long been found to be associated with Epizootic Ulcerative Syndrome (EUS) although the presence of granulomas caused by the fungus Aphanomyces invadans is currently used as the diagnostic criterium ...
Cross-sectional survey of epizootic ulcerative syndrome (EUS) cases in Bangladesh
(Fish Health Section, Asian Fisheries Society, 2002)
An interview-based questionnaire survey of one fish farmer and one fisherman randomly selected in each of the 64 districts of Bangladesh was carried out to study prevalence of EUS, and risk factors associated with EUS ...
Isolation of FV3-like iridovirus from a cutaneous ulceration disease of cultured frog, Rana tigrina Cantor, in Thailand
(Fish Health Section, Asian Fisheries Society, 2002)
A new frog disease occurred in frog culture farms located in Central Thailand since early 1998. The disease affects 20-100% of the frog population in affected farms. Diseased adult frogs usually exhibit ulcerative lesions ...
VP2 protein carries neutralization epitopes in blotched snakehead virus (BSNV)
(Fish Health Section, Asian Fisheries Society, 2002)
A new aquabirnavirus (BSNV, blotched snakehead virus) was isolated from a persistently infected warmwater fish cell line (BSN) developed from blotched snakehead (Channa lucius). Four polypeptides of molecular mass 112 ...
