[0036] The content of the present invention will be further explained by specific examples below.

[0037] (1) Preparation for aquaculture tidal flats:

[0038] Choose an area of ​​12000m2 in Fenzhou Village, Lianzhou Town, Doumen District, Zhuhai City 2 The bottom of the abandoned pond is leveled to meet the conditions for natural drainage; after the pond clearing and disinfection of the aquaculture tidal flats, the east corner of the tidal flats will be buried with a mesh for 120m 2 In the thick marked area, the colored stripe cloth is buried at the bottom of the pond 40cm deep; in the thick marked area, equipped with a blower, installed air stone inflatable, the air stone is at most 0.5m 2 One, the amount of aeration is based on the visible microwave on the water surface; shading nets and plastic films should be built in the standard thick area.

[0039] (2) Water regulation:

[0040] Inject fresh water 15 days before the seedlings are placed, and set up a 200 mesh, 100 mesh, and 60...

Abstract

The invention provides a tylorrhynchus heterochaetus semi-artificial seedling culture mudflat aquaculture method, which comprises the steps of parent selection, artificial impregnation, artificial incubation, seedling culture pool preparation, artificial seedling culture and intensive aquiculture. Through the steps of tylorrhynchus heterochaetus aquaculture mudflat preparation, water body regulation, seedling desalting, intermediate culture region seedling placing density, intermediate culture period feeding, standard rough period water quality management, aquaculture period management and aquaculture harvesting, tylorrhynchus heterochaetuses are helped to pass through setiger juvenile period in modes of staged desalting, feeding and the like, so that the semi-artificial seedling culture mudflat aquaculture of the tylorrhynchus heterochaetus is realized; the seedling survival rate of the tylorrhynchus heterochaetus is effectively improved; the mudflat aquaculture benefit of the tylorrhynchus heterochaetus is improved.

Description

[0001] 【Technical field】 [0002] The invention relates to an artificial breeding and breeding method for special aquatic products, in particular to a tidal flat breeding method for semi-artificial seedling cultivation of grass insects. [0003] 【Background technique】 [0004] Grass worm, scientific name Tylorrhynchus heterochaetus, belongs to Invertebrate Annelids, Polychaetes, Migratory Order, Nereistae, and Tylorrhynchus heterochaetus in systematic classification. Grass worms belong to estuary species, and different from traditional clamworm species in seawater areas, the larvae of grass worms can grow in fresh water. Because the grass insect lives in the paddy field for a period of time in its life cycle, people mistakenly believe that the grass insect feeds on the grass seedlings, so it is called the grass insect. [0005] Wo Chong is also known as the "Cordyceps sinensis" in the water. It has always been regarded as a delicacy in the Pearl River Delta. It has the medicin...
