Abstract: In order to research the effects of nanomaterials on carp growth and physio-chemical properties of the water, an experiment of carp aquiculture was conducted in lab condition on the effect of nanomaterial on small carps and physio-chemical properties. The result indicated that all the nanomaterial treatments could increase fish-survival rate. Nanonet treatment was the best among all treatments, showing survival rate with 100% increase, while water nitrite and nitrate decrease, nitrite decrease as low as 1/4 of control group. Nanomaterial increased water pH. The water quality was improved obviously. Nanotechnology has showed a broad prospect in aquiculture.

Key words：nanomaterial; nitrite; nitrate; aquiculture
