Adopt the utility model provides a device is to pinctada fucata base sowing breeding method, including following step:

firstly, marking the pinctada fucata fries to be about 2cm thick in a sea area in a mesh bag hanging culture mode;

then, the bottom sowing plate 1 is tightly paved in a cement pool, clean seawater is added, the bottom sowing plate 1 is submerged, the pinctada fucata martensii is uniformly sown on the bottom sowing plate 1, young pinctada fucata martensii is temporarily cultured in the cement pool for 1 day, and the pinctada fucata martensii is fixed on the bottom sowing plate 1 after the pinctada fucata martensii grows out of sufficient filaments;

selecting shallow sea mudflats with good sea water quality, smooth water flow and sandy bottom, driving the shallow sea mudflats into the fixed columns 3 at a certain interval below the lowest ebb level, and tying the two ends of the connecting ropes 2 to the fixed columns 3;

taking the bottom sowing plate 1 for planting the young pinctada fucata martensii out of the cement pond, fixing the bottom sowing plate 1 on the connecting rope 2 through the binding bar through holes at a certain interval, and performing daily management in the breeding process of the pinctada fucata martensii.

Specifically, when the bottom sowing plate is used, the fixed column 3 is inserted into shallow sea beach sand, two ends of the connecting rope 2 are tied to the fixed column 3, the bottom sowing plate 1 is fixed on the connecting rope 2 through the hole 14 by a binding strip, and the bottom sowing plate 1 is contacted with the seabed through 4 supporting legs, so that a certain interval is formed between the attachment surface of the bottom sowing plate 1 and the seabed. The shellfish of about 2cm is uniformly attached to the bottom sowing plate 1 by means of byssus, and the bottom sowing plate forms a certain space with the seabed through the support of 4 supporting legs. When the pinctada fucata dunker produces excrement, the excrement falls onto a shoal from the hollow part of the supporting plane, and the excrement is taken away along with the rise and fall of tidal water, so that the water quality and the substrate in the aquaculture sea area can be kept in a good state for a long time. The pinctada fucata is uniformly attached to the surface of the bottom sowing plate, so that the competition relationship between the pinctada fucata and bait in space is reduced, the mutual interference is less, and the rapid growth rate can be kept among individuals. All pinctada fucata dungs are flatly paved on the bottom sowing plate, convenience can be brought to daily cleaning, and the attached organisms on the surfaces of the pinctada fucata dungs can be removed only by flushing with a high-pressure water gun, so that the labor amount and the labor cost can be reduced for the whole breeding process.
