Detection of pesticide residues in aquaculture products
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
Agricultural chemicals such as fertilizers and pesticides have made an important contribution to agriculture. Pesticides protect crops from pests and diseases. They have brought about large yield increases, and have helped ...
Introduction to nutrition in tropical aquaculture
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2002)
Fish is a vital component of food security especially in developing countries of the world. As the world population grows, the need for more food and more fish has correspondingly increased. Aquaculture, the farming and ...
Minimal inhibitory concentration (MIC) test and determination of antimicrobial resistant bacteria
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
The agar dilution technique is used to measure qualitatively the in vitro activity of an antimicrobial agent against the test bacteria. In this method, graded amounts of antibiotics are incorporated in agar plates and ...
Bacterial isolation, identification and storage
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
Bacterial isolation, purification and identification are the first steps to bacteriological studies. Isolation is done to obtain pure bacterial cultures. Bacteria are usually isolated from fish kidney and spleen; and from ...
Parasitic diseases and pests
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2001)
A wide variety of parasites have been identified as causing significant economic losses in fish and shrimp culture. Most of these parasites are difficult to control effectively with a single measure. The control of parasites ...
Immunological and molecular biology techniques in disease diagnosis
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2001)
The improvement of existing immunoassay techniques, development of monoclonal antibody technology and the development of new immunoassay approaches are all working together to provide new tools for the detection of ...
Harmful and toxic algae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2001)
The chapter provides basic facts about harmful and toxic algae. It also discusses the conditions that stimulate their occurrence, different types of harmful and toxic algal blooms and their effects to fish and marine ...
Disk diffusion method
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
Disk diffusion method is based on the principle that antibiotic-impregnated disk, placed on agar previously inoculated with the test bacterium, pick-up moisture and the antibiotic diffuse radially outward through the agar ...
Viral diseases
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2001)
Outbreaks of viral infections can cause massive mortalities among cultured fishes or shrimps. Water temperature and age of the fish or shrimps are significant factors that influence the development of viral infections. ...
Bacterial diseases
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2001)
Fish and crustaceans that are not weakened by poor environmental conditions, or by other causes, such as parasitic infestation, nutritional deficiency, handling stress, or chemical intoxication, are more resistant to ...
