Sažetak
The use of antimicrobials in European aquaculture has decreased markedly in the past decade, mostly due to the development of vaccines. However, use of only few antibiotics for treating all the bacterial diseases of fish, and only in approved species, may lead to the development of the bacterial drug resistance. A large proportion of antibiotics used in fish is applied in subtherapeutic doses and not for the treatment of sick animals. "Disease prevention" describes prophylactic actions taken to stave off the spread of a disease. These decisions can be made bythe fish farmer acting alone, without any involvment of a veterinarian. Because of the lack of control on duration of prescribed treatment for the sick fish, farmers can modulate the length of application of medicated feed to fish, and thus attribute to the development of resistance. Also, the suggested withdrawal periods before marketing the fish are not always respected. Since farmed fish, when treated with antibiotics, are fed medicated feeds, antibiotics enter the environment either in fish feces or uneaten food, could accumulate in sediments, and could also affect the flora of wild fish. Several factors could reduce the uses of antibiotics in fish farming: increased concerns about drugs in food ; greater appreciation of the threat of antibiotic-resistant bacteria ; better fish husbandry that reduces the need for antibiotics ; legislative and regulatory initiatives ; development of good management practises, including preventive measures aiming to avoid introduction of new pathogens and the spread of diseases to farmed and wild stock. The scientific research interests should focus on mechansms of drugs resistance ; persistence of resistant strains in fish ; appropriate dosage, route and duration of administration for every fish species of interest ; appropriate post-approval monitoring procedures. The transference of antimicrobial drug resistance from fish to humans is hypothetically possible, yet unproved concern. However, consumers should be afforded the opportunity to avoid consumption of food products containing drug residues.
