Sažetak
The aim of this study was the assessment of the microbial marine water quality in bluefin tuna (Thunnus thynnus) farm. Microbial parameters (heterotrophic bacteria, Vibrio, coliforms, Escherichia coli and enterococci) were examined during normal and reduced feeding regimes. The major impact of tuna farm activity on marine water quality identified in this study was the enrichment of faecal bacteria in water column during tuna fattening (total coliforms: 20-17, 153 CFU/100 mL ; E. coli: 9-531 CFU/100 mL ; enterococci: 10-312 CFU/100 mL), whereas the bacterial concentrations significantly decreased during reduced feeding (total coliforms: 10-327 CFU/100 mL ; E. coli: 10-69 CFU/100 mL ; enterococci: 1-2.6 CFU/100 mL). Faecal water contamination was probably a direct consequence of abundant nutrition with fresh and defrosted fishes, which resulted in an overload of fish debris in the marine water on the farm, and attracted colonies of seagulls. The results gathered during this study revealed the presence of environmental problems associated with tuna aquaculture and pointed to necessity for development of sustainable approaches to deal with these problems.
