Isolation/Detection,There is no single technique suitable for the recovery of all known bacterial fish pathogens. Scientists need to use a combination of methods and incubation conditions to achieve pure cultures.

Epizootiology: Gram-positive bacteria,The reservoir of many Gram-positive bacterial fish pathogens is unknown. Whereas some groups, e.g. streptococci, occur in polluted waters, other organisms, e.g. ., seem to be restricted to fish. How do such organisms spread between separate fish populations?

Epizootiology: Gram-negative bacteria,The value of survival experiments based on laboratory cultures is questionable. Cultures grown on laboratory media tend to be larger and less aggressive than their “natural” counterparts. So, when laboratory cultures are added to experimental microcosms, the outcome need not represent the true fate of the organism in the aquatic environment.

Andrés Díaz Lantada,Jesús Carrillo Gil (Eklund et al., 1982). Characteristic disease symptoms seemed to be very vague, but fish have been observed to exhibit sluggish, erratic swimming, appeared to be listless, and may alternately float and sink, before showing temporary rejuvenation. This pattern was repeated until death eventually ensued (Cann and Taylor, 1982).

Handbook on Analyzing Human Genetic Datat in the study of fish diseases. To some extent, this will be justified by the continued expansion of aquaculture and the expected increase in outbreaks of disease. It seems likely that future developments will encompass the following.
