Using The Thick-Shelled River Mussel (Unio crassus) Filtering Ability for Water Treatment Process in Aquaculture Systems: an In Vitro Study on Removal of the Bacteria from The Water

The thick-shelled river mussel (Unio crassus) is listed as 'Endangered' on the IUCN Red List of Threatened Species and it important to culture them for conservation natural stocks. Integrating mussels into freshwater aquaculture system could be an efficient method, because their filtering ability. In this study, was aimed determine bacteria filtering ability if water quality got better in terms bacteriology. Depuration, disinfection, antibiotic treatments were applied reduce bacterial load mussels' bodies. Disinfection made using NaCl2 , 2-Phenoxyethanol, Formalin, Virkon® S Chloramine T. Antibiotic treatment performed Oxytetracycline Florfenicol. best result obtained group which 5 mg L-1 added. However, since can uptake same own bodies with pseudofeces, found that appropriate use depuration applications together. experiment keeping environment pathogens (Staphylococcus epidermidis, Aeromonas caviae), intense growth inoculated water. Thus, has been determined clean by removing from within 48 hours, so adapted systems aquatic bacteria.
