The Intestine Microbiota Community and Enzyme Activity in Trachinotus ovatus After Short-Time Antibiotic Bath Administration

The control of microbiota is essential for the prevention of bacterial and fungal diseases in aquaculture. Antibiotic is often used as an effective strategy for health management in fish farming. This chapter reviews and updates the recent research outcomes in preventing and treating bacterial infections in golden pompano Trachinotus ovatus. A short-time antibiotic bath administration was used with 5 mg enrofloxacin/L for 24 h. The results indicate that 5 mg/L enrofloxacin bath administration for 24 h did not induce mortality and affect the gut bacterial richness of golden pompano, but dramatically reduced pathogen bacteria. Furthermore, the short-time antibiotic bath administration is unlikely to result in a dysfunction of the anti-oxidative system or a digestive system disorder. Thus, 5 mg/L enrofloxacin bath administration is safe to prevent bacterial diseases in T. ovatus farming. This chapter sheds light on bacterial disease prevention and treatment to optimize the use of enrofloxacin in the T. ovatus farming to improve health management in the aquaculture of this economically important fish species.
