In Serbia there are about 17 ha for growing trout pond and 8,940 ha for the cultivation of carp and other warm-water fish. According to the statistical data, on these production areas the production in 2010 amounted to about 7,000 tons of carp fish and 1,200 tons of fish species. The main obstacle in the chain of intensive fish production rests on the bacterial disease, somewhat less parasitic and virology etiology kind. Reproduction and growth of bacteria in adverse growing conditions (insufficient water changes, presence of toxic gases, overcrowding of fish per unit area, low hydro reclamation and zoo hygienic conditions in the preparation of facilities for hatching), causes the disease. Conditional pathogenic bacteria from Aeromonas are common causes of disease. Due to a lack of monitoring and laboratory examination, the antibiotics used to combat bacterial diseases are used without an established antibiograms and often inadequate doses. All of these factors are detrimental to the development of resistance of the applicable antibiotics. Sensitivity analysis of isolates to antimicrobial drugs showed the presence of significant resistance to Flumequin and Oxitetraciklyne over 35% to 40%, while resistance to Oxitetraciklyne is close to 20% of examined cases. The resistance to Flumequin is still very low and resulted in only 2 %.These findings show that the antimicrobial drugs are used in inadequate manner and in the future it can be expected to further increase resistance and reduce the number of effective drugs. Considering that microorganisms are in question (Aeromonas hydrophila) which can endanger public health, the contagion especially in the case of reduced sensitivity to antibiotics can result in the danger to people.
