Aquaculture literature describes a large number of infectious and noninfectious diseases caused by various pathogenic agents. Crustaceans, as with other animals, are subjected to a wide spectrum of diseases. Such diseases require a somewhat different approach to solving the problem than terrestrial animals. Crustaceans are in an entirely different environment.
Pens, tanks and cages for crab fattening Various structures, including cages, floating cages, ponds or tanks , can be utilized to hold crabs for relatively short periods of time for fattening. As long as the crabs are held in water of suitable quality, fed regularly and precautions are taken to minimize disease, crabs for fattening can be held at reasonably high densities. Fattening operations may be constructed within an existing pond or pen, a tidal river or creek. More sophisticated systems can be operated in flow through or recirculating land-based aquaculture facilities.
All forms of aquaculture are susceptible to outbreaks of disease, as many pathogenic bacteria are normal inhabitants of the aquatic environment. Both in aquaculture facilities and in external aquatic environments, the occurrence of disease is a complex interaction between the host species, disease agents and the environment. In farm environments, outbreaks of disease are greatly influenced by the susceptibility of the hosts, the virulence of the pathogens and adverse environmental conditions. Farming practices may favor disease occurrence, as in the case of intensive and semi-intensive systems of production
The cure of certain Crustaceans disease is therapeutically possible therapy in general, as much in aquarium Crustaceans rearing as in Crustaceans farming, is of secondary importance to prophylaxis and hygiene. Diagnosis, prophylaxis and disease prevention and aquaculture hygiene has become subject offered by veterinarians.
The book includes 12 chapters: 1: Chapter 1: Epidemiology of Crustacean Diseases Diseases Chapter 2: Interactions of pH, Carbon Dioxide, Alkalinity ,Chapter 3: The Immune System, Chapter 4: Diseases of shrimp, prawn, crayfish and crabs, Chapter 5: Diseases of crabs and lobster , Chapter 6: Diagnosis of fish diseases ,Chapter 7: Shrimp farming ,Chapter 8: The farmers' choice of shrimp culture ,Chapter 9: Crab farms ,Chapter 10: Disinfection of aquaculture ,Chapter 11: Toxicity of Crustaceans and Chapter 12: Prevention and Therapy of Fish Diseases
. This edition aims to present some relevant topics in Crustacean diseases that may be of interest for veterinarian doctors and for the other interested in fish pathology. In addition, to translate advanced information in fish diseases, diagnosis and therapy.
