Development of bait motion bionics feeding equipment of Rana chensinensis

The bait simulating tempting feeding equipment was designed for factory breeding of rana chensinensis, which were to decrease its cost and risk and improve breeding environment. According to pre-arranged plannings and preparatory experiment, three axial cam driving of distinct phases was determined to be the best project. According to the best project, model machine was designed and made, and feeding experiments were carried out. The equipment only covers an area of 0.48 m2 in every pond, and it has characteristics of low cost and easy operation. The maximal rate of rana chensinensis feeding attained 79.2%. Results indicated that the bait motion bionics from the equipment can meet rana chensinensis feeding requirement, which achieved satisfactory effect.
