Diseases of milkfish
MetadataShow full item record
Although the history of Chanos chanos culture has been quite long, reports of major epizootics have been few. Trained manpower and disease diagnostic services in most milkfish growing areas have not been readily available. Hence, earlier reports of etiologic agents of these epizootics were limited mostly to direct microscopic examination of specimens. Significant disease cases reported were attributed to bacterial, myotic, parasitic, and toxic causes. Bacterial infections, primarily due to Vibrio sp., have been frequently associated with mortality. To a lesser, extent fungal infections have also been reported. Intoxication of stock in freshwater systems by Microcystis toxins has caused massive fish kills in Laguna de Bay, Philippines. In most instances, affected fish were predisposed by environmental stress incurred in handling storage and transport. The fry and fingerling stages seemed severely affected compared with the older stages. Control of these infections must include assessment of fish husbandry practices first, before the use of chemotherapeutic agents like antibiotics is considered.

BookA textbook on diseases of cultured warmwater fish and shrimps in the Philippines. Eleven chapters cover essential information on the basic principles of disease causation, major diseases of cultured fish and crustaceans, particularly shrimps, and methods of prevention and control. Emphasis is made on major diseases that occur in the Philippines and other countries in the Asian region. Included also are topics on harmful algae, immunology and molecular biological diagnostic techniques.

Series: Aquaculture extension manual; No. 16The manual provides information on the diseases that affect the 3 major species of shrimps cultured in the Philippines: Penaeus monodon, P. merguiensis and P. indicus. It includes the common name of the disease, causative agent, species affected, stages affected, gross signs, effects on the host and methods of prevention and treatment. This revised edition includes newly discovered diseases. It is hoped that the manual will be of considerable help to shrimp farmers in identifying the disease and lead to prevention or early disease diagnosis and control.
