The invention discloses a submersible type fishing net. The submersible type fishing net comprises a fishing net, an air inflation hose, an air inlet pipe, an air outlet pipe, a pulling rope, a sealing pipe and an air pump, wherein the fishing net is arranged on the air inflation hose, the air inlet pipe and the air outlet pipe are arranged between the air inflation hose and the air pump, and the pulling rope is arranged on the air inflation hose; the first end and the tail end of the air inflation hose are connected through the sealing pipe, and the air inflation hose can be discharged through the air pump. The submersible type fishing net can sink to the water bottom under the action of a gravity and can ascend stably as the air inflation hose is inflated through the air pump, thus fish schools cannot be scared, the fishing net can be pulled out of the water surface through the pulling rope after the air inflation pipe floats to the water surface, and the fishing efficiency of a fisherman can be greatly increased.
