Use of bacteria as biological control agent against microbial diseases in shrimp (Penaeus monodon) and crab (Scylla serrata) hatcheries: Part II. Application of probiotics in natural food and artificial feeds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
The suitability of probiotic bacterial incorporation into artificial diets was tested with inferior results due to the interference of heat-resistant starins that are associated with several feed ingredients. However, ...
Detection and transmission of the koi herpesvirus (KHV)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
The isolations of KHV were conducted on samples collected from Indonesia, Taiwan and Vietnam. No virus was isolated from koi and common carp from the first two countries although PCR tests of samples from Taiwan were ...

Development of immunological indices for monitoring health status in shrimp (Penaeus monodon)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
Some hemolymph parameters were determined as non-invasive early-warning indicators of health status in black tiger shrimp (Penaeus monodon). These included total hemocyte count (THC), respiratory burst activity, phenoloxidase ...
Parasites of commercially-important marine fish cultured in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
The commercially-important cultured marine fish, orange-spotted grouper (Epinephelus coioides), mangrove red snapper (Lutjanus argentimaculatus) and rabbitfish (Siganus guttatus), were examined at regular intervals to ...
Detection and identification of viral pathogens in marine finfish cultured in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
This is a summary of investigations conducted on 91 disease/mortality cases observed among marine fish: groupers (Epinephelus coioides, E. malabaricus), sea bass (Lates calcarifer), rabbitfish (Siganus spp.), red snapper ...
Development of monoclonal antibody (MAb) against monodon baculovirus (MBV) and hepatopancreatic parvovirus (HPV)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
Antibody-based detection methods are relatively simple and rapid, aside from being specific and sensitive. Thus, there is a necessity to develop such techniques for early and rapid diagnosis of viral pathogens such as MBV ...
Standardization of PCR techniques as the detection method for white spot syndrome virus (WSSV) infection in shrimp (Penaeus monodon)
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
Several runs were conducted using the three published PCR protocols and the three DNA extraction methods. All three primer pairs designed by individual authors based on the sequence of a cloned fragment of the white spot ...
Important parasites of freshwater fish in Thailand and neighboring countries
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
Snakehead fish (Chana striata) from Thailand and Cambodia were sampled for parasitological study. The project was carried out from August 2003 to January 2004 twice a month. The results showed that there were 22 genera ...
Important parasites of catfish (Clarias macrocephalus) in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
The parasite fauna of broad head catfish (Clarias macrocephalus) was determined through regular examination of cultured and wild-caught fish. Collection areas included hatchery, nursery and grow-out facilities in Iloilo ...
