Parasitic diseases
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
A wide variety of parasitic organisms have been reported as causing significant problems in grouper aquaculture. In the hatchery and nursery stages, parasitic diseases of groupers are caused predominantly by protozoans, ...
Viral diseases
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
Some viral infections are serious diseases of groupers causing heavy mortalities. In most cases, larval stages are the most susceptible stage. With the carnivorous nature of groupers, they can readily ingest viral pathogens ...
Bacterial diseases
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
Bacteria are very common in the aquatic environment. Most bacterial disease agents are part of the normal flora of the water. They cause disease only when the fish are stressed due to poor environmental conditions, inadequate ...
Nutritional diseases
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
Nutritional diseases of fish may develop as a result of deficiency (undernutrition), excess (overnutrition), or imbalance (malnutrition) of nutrients present in their food. The disease usually develops gradually because ...
Environmental diseases
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
This chapter focuses on swimbladder stress syndrome and gas bubble disease, the two most common disorders due to adverse environmental conditions.
Fungal diseases
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
The incidence of ichthyophoniosis in groupers (Epinephelus) has been reported in Plectropomus sp. in Singapore and Cromileptes altivelis in Indonesia. It has also been known to infect at least 80 other species of teleost ...
Mechanism of control of luminous vibriosis in shrimp-finfish integrated water system
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
The disease due to luminous bacteria has been a major problem of the shrimp (Penaues monodon) industry. Different technologies have been introduced to prevent the occurrence of luminous bacteria in shrimp ponds. In the ...
Establishment of preventive measures against viral nervous necrosis (VNN) in finfish hatcheries
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
The establishment of preventive measures against viral nervous necrosis (VNN) at the finfish hatcheries of SEAFDEC Aquaculture Department in Iloilo, Philippines, was instituted primarily to minimize the impact of the viral ...
Antibacterial metabolites in the microbial and phytoplankton flora of the "green water" culture of shrimp (Penaeus monodon): Part II. Fish mucus and luminous Vibrio
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
Experiments on the presence of anti-luminous Vibrio properties in marine fish species cultured in the Philippines, i.e., jewel tilapia (Oreochromis hornorum), red tilapia (hybrid of Oreochromis niloticus and O. mossambicus), ...
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 ...
