Sweetfish (for 3 weeks) and rainbow trout (for 6 weeks) were kept either within air-nanobubble water or within normal
water. Finally, 5 week-old male DBA1/J mice were bred with normal free-chaw and free-drinking either of oxygennanobubble
water or of normal water for 12 weeks. Oxygen-nanobubble significantly increased the dissolved oxygen
concentration of water as well as concentration/size of nanobubbles which were relatively stable for 70 days. Airnanobubble
water significantly promoted the height (19.1 vs. 16.7 cm; P,0.05), length of leaves (24.4 vs. 22.4 cm; P,0.01),
and aerial fresh weight (27.3 vs. 20.3 g; P,0.01) of Brassica campestris compared to normal water. Total weight of sweetfish
increased from 3.0 to 6.4 kg in normal water, whereas it increased from 3.0 to 10.2 kg in air-nanobubble water. In addition,
total weight of rainbow trout increased from 50.0 to 129.5 kg in normal water, whereas it increased from 50.0 to 148.0 kg in
air-nanobubble water
