The invention provides a support rod type purse seine aquaculture engineering shore connecting technique. A purse seine, a support rod and a pile foundation are included, the bottom of the support rod is connected with the pile foundation, a fixing support is connected to the top end of the support rod, a groove is formed under the support rod, and the purse seine is connected with the support rod and the groove separately and connected with the groove through an expansion block; the bottom end of the support rod is provided with a hemisphere, the surface of the support rod is provided with a round convex block, the bottom end of the support rod is connected with the pile foundation through concrete pouring, the surface of the support rod is provided with a seine tying ring, and the purse seine is connected with the support rod through the seine tying ring. Groove excavating is conducted under the support rod to form the groove with the certain depth and width, then the purse seine is filled with the prepared expansion block for fixing, therefore, it is guaranteed that fixation between the purse seine and a seashore is effective for a long time, the fixing effect is obviously improved and is excellent, and an anti-escape effect is achieved and is excellent. According to the technique, implementation is easy, the structure is stable, a netting is not prone to be damaged, the fixing equipment is resistant to corrosion, and the aquaculture safety and the escape resistance are high.
