The surge aerator aerator floats on the sparkling water like a lifebuoy, and the splashes of the waterwheel-type variable frequency aerator form small fountains... This scene of a "water park" takes place in The observation site of the first national aquaculture mechanization meeting. This meeting was hosted by the Department of Agricultural Mechanization Management of the Ministry of Agriculture and Rural Affairs and was held in Jintan District, Changzhou City, Jiangsu Province recently. More than 200 people including Wang Jiayun, Deputy Director of the Department of Agricultural Mechanization Management of the Ministry of Agriculture and Rural Affairs, and relevant department heads, experts, scholars, and business representatives attend.
