Nanobubbles of oxygen and ozone are effective tools for pathogen treatment and for improving the survival rates of common carp larvae (Cyprinus carpio) - A case study

Popis výsledku v původním jazyce

Nanobubble technology has demonstrated significant potential in enhancing the effectiveness of oxygen and ozone for water treatment and pathogen control. This study identifies the potential application of oxygen and ozone nanobubbles in improving the hatching efficiency of common carp eggs. Preliminary results indicated that an O3NB concentration of 0.5 mg/L was effective in treating Saprolegnia spp. However, concentrations of 0.1-0.3 mg/L caused severe gill damage and significant mortality in fish larvae. Therefore, in this study, O3NB was applied to fish embryos at 24 h post-hatch at concentrations of 0.46 +/- 0.04 to 0.55 +/- 0.06 mg/L for 1 h (T1), 2 h (T2), and 3 h (T3). Following this, from 48 h post-hatch, oxygen nanobubbles (O2NB) were used to maintain optimal oxygen levels (9.98 +/- 0.10 to 12.12 +/- 1.04 mg/L) for common carp hatching. Embryo development and the presence of pathogens were assessed at 6, 24, 48, and 72 h. The results showed that the administration of O3NB had no negative effect on the development of carp embryos. No Saprolegnia spp., Dermocystidium spp., and Fragilaria spp. were observed on embryos treated with O3NB. In the control group, infection rates were 12.67 %, 3.33 %, and 73 %, respectively. At 72 h, the T1, T2, and T3 treatments had decreased rates of gill fungus infection (13.67 +/- 5.51 %, 7.67 +/- 0.58 %, and 5.33 +/- 1.15 %, respectively) compared to the control (84.67 %, P &lt; 0.05). The larvae survival rates after 72 h in the three treatments using O2NB and O3NB were higher compared to the control, with the T2 group achieving the highest effectiveness at 94.07 +/- 0.90 %. Our findings indicate that the application of O2NB and O3NB at appropriate developmental stages improves hatching efficiency in common carp.
