Pond culture is one of the modes of seawater culture, and is more and more widely applied in recent years due to high controllability of culture environment. When the seawater shellfish is cultured in the pond, seawater is introduced into the seawater culture pond, and the shellfish is further cultured in the seawater culture pond. Shellfish such as oyster are put in the net cage and then sink in the water in the mariculture pond. The cultivation of the microalgae is usually carried out in a seawater culture pond, and the microalgae in the seawater not only can provide food for the shellfish, but also has the function of regulating the water quality of the seawater pond. However, when the density of microalgae in the seawater pond is too high or the composition of microalgae communities is unreasonable, the problems of water deterioration or eutrophication and the like are easily caused, and further, a great amount of cultured shellfish is dead, so that the method has important significance for regulating and controlling the quality of microalgae in the shellfish growth environment.

step S1, introducing the inactivated seawater into each culture unit 11, respectively putting microalgae into each culture unit 11 according to the type of the cultured shellfish, and performing directional culture on the microalgae communities in each culture unit 11.
Step S2, sampling the seawater in the cultivation unit 11, detecting the species and density of microalgae in the seawater sample of the cultivation unit 11, opening the feeding partition valve 22 at the corresponding feeding channel when the quality of the seawater microalgae community in the cultivation unit 11 reaches a set standard, and introducing the seawater in the cultivation unit 11 into the corresponding cultivation unit 21 through the feeding channel.
Step S3, the shellfish seedlings are arranged in the feeding net cage 6, and the feeding net cage 6 is arranged on the raft body 5; and hoisting the raft body 5 by using the hoisting device 9, and then conveying the raft body 5 to the corresponding culture unit 21 position by using the carrying trolley 8. The raft body 5 is placed in the culture unit 21, the hooks 53 on the two sides of the raft body 5 are hooked with the positioning hanging rings 71 on the positioning ropes 7, and then the raft body 5 is positioned and installed in the culture unit 21.
The environmental seawater of each culture unit 21 is sampled and detected periodically, when the microalgae species and density of the environmental seawater in the culture unit 21 exceed the set range, the seawater in the corresponding culture unit 21 is discharged into the discharge pond 3, and new environmental seawater is introduced from the culture unit 11. After the seawater discharged into the discharge pond 3 is settled for 4 to 6 hours, the algae collecting mesh bag 33 in the settling tank 32 is taken out, and then the microalgae in the algae collecting mesh bag 33 is dried and crushed; the water in the discharge tank 3 is deactivated and discharged to the environment.
And step S4, checking the growth condition of the shellfish in each culture unit 21 regularly according to the growth cycle of the shellfish. The worker walks along the walking bridge 4, and takes the net cage 6 away from the raft body 5 by holding the hooking tool and further utilizing the operating ring 64, so as to sample and detect the shellfish growth condition of the corresponding culture unit 21; when the growth condition of the shellfish reaches the standard, the raft body 5 is transported away from the culture unit 11 through the carrying trolley 8 and the hoisting device 9.
Although some specific embodiments of the present invention have been described in detail by way of illustration, it should be understood by those skilled in the art that the above illustration is only for the purpose of illustration and is not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
