Embodiment Construction

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

[0037] (1), tidal flat preparation:

[0038] Select a site with an area of ​​12,000m2 in Fenzhou Village, Lianzhou Town, Doumen District, Zhuhai City 2 The bottom of the abandoned pond was leveled to meet the conditions of natural inflow and drainage; the aquaculture tidal flat was sterilized by clearing the pond, and at the east corner of the tidal flat, a 120m net was buried with colored strips of cloth. 2 In the marked thick area, the color strip cloth is buried at the bottom of the pond to a depth of 40cm; in the marked thick area, a blower is equipped and an air stone is installed to inflate the air stone. The air stone is 0.5m at best 2 One, the amount of air to be inflated is subject to the visible microwave on the water surface; shade nets and plastic films need to be built in the standard thick area.

[0039] (2), water regulation:

[0040] Inject fresh water 15...

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...
