    Furunculosis is an important systemic bacterial disease found among finfishes both in culture systems and in the wild. This disease was originally described by Emmerich and Weibel in 1894 isolating the causative bacterium from hatchery trout from Germany

    Fish and shellfish diseases in culture systems IV. Bacterial diseases

    Get PDF
    All living beings, in their natural surroundings, become susceptible to diseases one time or the other in their life. Fishes and shellfishes are also no exception.Even in the natural conditions, a few of fishes and shellfishes become diseased and most of the cases pass unnoticed possibility due to lack of interest

    Just as in land animals or in agricultural crops fishes and shellfishes living in the aquatic environment are susceptible to diseases whenever certain abnormal biological, physological or environmental changes occur

    Handbook on diagnosis and control of bacterial diseases in finfish and shellfish culture

    Just as in the husbandry of land animals or in the production of agricultural crops, disease occurs in the culture of fishes and shellfishes. The problem of diseases has assumed considerable significance with the rapid developments that are now occurring in the culture of aquatic species. New diseases are occurring in intensive culture systems, whether they are under experimental conditions or in grow out systems, and unless we have a sufficient knowledge of the nature of these diseases and their control, aquaculture practices can hardly become successful. An attempt is made here to define disease and pathogen, and different categories of diseases
