Abstract:A multidisciplinary approach was used to study the impact of fish farming on coastal bacterial communities in the inner part of the Bay of Piran (northern Adriatic). Differences in bacterial abundance, production and the occurrence of selected bacterial groups were studied in the water column around the cage and at different distances from the centre of the fish cage towards the open water, i.e., reference marine station. We also examined the effect of fish feeding on the surrounding system in a short-term in situ experiment based on the simultaneous collection of seawater samples from different locations around the fish cage before and after feeding of fish. Our study suggests that fish feeding has a moderate short-term effect on water column parameters, including bacterial abundance and production, only at a limited distance from the fish cages. The nitrifying, ammonia-oxidizing bacterial groups, as determined by the fluorescent in situ hybridization method, were represented at a higher percentage in the seawater samples in the middle and around the fish cages. β- Proteobacteria, γ-Proteobacteria and the Cytophaga-Flavobacterium group were represented to a higher percentage at sampling sites in the middle of the Bay of Piran and at the reference marine station. The Vibrio group was detected at all sampling sites. The accumulation of organically enriched fish food and waste products released into the seawater during the short-term experiment resulted in a significant increase in particulate matter, orthophosphate and ammonium. In response to the increase in inorganic nutrients, we observed a significant increase in bacterial production, while no significant differences were observed in bacterial abundance in such short time.

Title:Kratkotrajne spremembe mikrobne združbe v vodnem stolpcu okoli ribogojnice v Piranskem zalivu
Abstract:Vpliv ribogojstva na bakterijske združbe smo proučevali z multidisciplinarnim pristopom v notranjem delu Piranskega zaliva (severni Jadran). Razlike v številčnosti bakterij, bakterijski produkciji in pojavljanju izbranih bakterijskih skupin smo preučevali v vodnem stolpcu okoli ribje kletke in na izbranih lokacijah od središča ribje kletke do odprtih vod. Spremembe pred in po hranjenju rib smo preučili tudi v kratkoročnem poskusu in situ, ki je temeljil na istočasnem vzorčenju morske vode na različnih lokacijah okoli ribje kletke. Naša študija kaže, da hranjenje rib kratkoročno zmerno vpliva na parametre vodnega stolpca, vključno s številčnostjo bakterij in produkcijo, in le na omejeni razdalji od ribjih kletk. Nitrifikacijske bakterije, ki oksidirajo amonij, določene s fluorescentno in situ hibridizacijsko metodo, so bile zastopane v višjem deležu v vzorcih morske vode v sredini in neposredni okolici ribje kletke. β-Proteobakterije, γ-Proteobakterije in skupina Cytophaga-Flavobacterium so bile zastopane v višjem odstotku na bolj oddaljenih vzorčnih mestih. Potencialno patogena vrsta Vibrio je bila prisotna na vseh mestih vzorčenja. Kopičenje organsko obogatene ribje hrane in odpadnih produktov, ki se sproščajo v morsko vodo v kratkem času po hranjenju, je povzročilo znatno povečanje koncentracij partikulatne organske snovi, ortofosfata in amonija. Kot odgovor na povečanje anorganskih hranil smo izmerili bakterijsko aktivnost, medtem ko razlik v biomasi v vodnem stolpcu ni bilo opaziti.
