Antibiotics are used by meat producers to improve animal production and treat disease. These are administered to beef and dairy cattle, swine, broiler chicks and laying hens. 16 Prophylactic antibiotics are also widely administered in finfish aquaculture to prevent bacterial infections that result from poor sanitation in fish farming. 17 ...

PHA can also be employed as an antibacterial agent against disease outbreaks. Short-chain fatty acid PHA were found to be effective in inhibiting the growth of a virulent Vibrio campbellii strain which is known to infect molluscs, finfish, lobsters and shrimp. The assumption was made that when the PHA particles degraded into P-hydroxybutyrate, fatty acids were released in the guts of Artemia nauplii. The use of smaller sized PHA particles could also improve the survival of infected Artemia nauplii more effectively [30]. In a different study conducted by Nhan and co-workers [31], Artemia nauplii were fed a lipid emulsion rich in highly unsaturated fatty acids and PHA. This technique, known as lipid enrichment, was employed... 

Table 5.1 Rapid diagnostic methods reported for the detection and identification of pathogens causing disease in finfish, molluscs and crustaceans...

The number of diseases reported in finfish and the methods used to detect the causative agents is vast (reviewed by Adams, 2009). The diseases currently listed as notifiable by the OIE include epizootic haematopoietic necrosis (EHN) epizootic ulcerative syndrome (EUS) gyrodactylosis (Gywdactylus 5fl/ ris) infectious haematopoietic necrosis (IHN) infectious salmon anaemia (ISA) koi herpesvirus disease (KHVD) red sea bream iridoviral disease (RBID) spring viraemia of carp (SVC) viral haemorrhagic septicaemia (VHS) (OIE, 2011). 

Bacteria are the principal and most significant pathogens in cultured and wild finfish and shellfish worldwide. In aquaculture, bacteria occur in nurseries, during rearing and in grow-out ponds, causing heavy mortalities and serious economic losses to farmers. The important bacterial diseases in...
