Biology and pathogenicity of the gill monogenean of grouper (Epinephelus coioides) cultured in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
The diplectanid monogenean Pseudorhabdosynochus lantauensis was the most abundant parasite recovered from the gills of cultured orange-spotted grouper (Epinephelus coioides) in the Philippines. The morphology of P. lantauensis ...
Use of bacteria as biological control agent against microbial diseases in shrimp (Penaeus monodon) and crab (Scylla serrata) hatcheries: Part III. Application of probiotics in culture water and surfaces
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
Strain C1 is a bacterial isolate, which can reduce luminous bacteria in seawater, and thus a potential probiotic in crab larval rearing system. A delivery method through colonized substrates like plastic beads, window pane ...
Parasites of grouper (Epinephelus coioides) cultured in Thailand
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
Orange-spotted grouper (Epinephelus coioides) cultured in Thailand were examined for their parasites. There were five parasitic groups found in this investigation, viz., protozoans (four genera), monogeneans (five genera), ...
Establishment and application of prevention and control methods against parasites of fish cultured in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
The efficacy of bath treatment methods against the ectoparasites Amyloodinium ocellatum, Pseudorhabdosynochus lantauensis and Zeylanicobdella arugamensis on marine fish was determined under laboratory conditions. The ...
Experimental evaluation of probiotics as biocontrol/bioremediation in the rearing of shrimp (Penaeus monodon)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
Two hundred fifty-liter (250-L) fiberglass tanks each equipped with 15-L capacity filter tanks are adequate for screening of commercial probiotics. The application of some commercial probiotics in the culture water is more ...
Use of bacteria as biological control agent against microbial diseases in shrimp (Penaeus monodon) and crab (Scylla serrata) hatcheries: Part I. Isolation and selection of bacteria for biological control in crustacean hatcheries
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
A study aimed at obtaining a biological control agent against bacterial diseases of hatchery-reared shrimps and crabs was conducted. Bacteria were isolated from crustacean rearing environments where luminescent vibriosis ...
Detection and identification of viral pathogens of grouper (Epinephelus malabaricus) cultured in Thailand
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
A virological survey was conducted in brown-spotted grouper (Epinephelus malabaricus) cultured in cages, earthen ponds and pens from April 2001 to January 2002 on the east and south coasts of Thailand. The adult grouper ...
Leech infection in grouper (Epinephelus coioides) in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
The effect of infection with the leech Zeylanicobdella arugamensis on the hematological parameters in orange-spotted grouper (Epinephelus coioides) was determined. The hematocrit, hemoglobin and total plasma protein of ...
Prevalence of economically-important viral diseases in wild shrimp (Penaeus monodon) in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
Prevalences of white spot syndrome virus (WSSV) and monodon baculovirus (MBV) were determined using polymerase chain reaction (PCR) as the detection method in wild black tiger shrimp (Penaeus monodon) collected from seven ...
Detection and identification of iridoviral pathogens of freshwater fish in Thailand
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
An iridovirus or ranavirus survey was conducted in Thailand during April 2003 to March 2004. Five hundred and sixty-six diseased plus healthy fish and frog specimens were examined for the possibility of ranavirus infection ...
