Problems solved by technology

According to the production survey of the bare square star worm farm area and related literature, it is known that high-density culture in ponds can achieve high yields of square star worms, but the basic conditions for pond culture are high, and there are very few areas suitable for high-density culture , and tidal flat farming is the main way of artificial breeding of naked square star insects at present. According to this traditional breeding method, the average yield of good breeding is 100-120kg / mu, and the output of most of the breeding areas is 30-50kg / mu , which makes it difficult to realize efficient utilization of large-scale tidal flats, and the tidal flat resources are not fully utilized

Embodiment 1

[0024] Breeding steps:

[0025] (1) Breeding site

[0026] The site is the intertidal area in the middle and upper part of the coastal tidal flats in the south, with a sand content greater than 70%, benthic diatoms growing on the surface, seawater salinity 14-33, no oil pollution and far away from domestic sewage, with a breeding area of ​​18 mu;

[0027] (2) Treatment of breeding grounds

[0028] Mark the breeding area with sticks, every about 200m 2 The area mark is surrounded by a square, moved higher and filled lower, and filled with sand in the deeper water storage, so that the sand layer in the area is slightly lower than the surrounding beach surface, and sandbags are used as water retaining materials to form a tight circle around the breeding area to ensure the ebb tide in the breeding area There is water at the back, the water depth is 1-3cm;

[0029] (3) Seed sources and specifications

[0030] Purchasing artificially propagated seeds, the specification is 0.1g-0...

Embodiment 2

[0038] Breeding steps:

[0039] (1) Breeding site

[0040] The site is located in the intertidal zone in the middle of the coastal tidal flats in the southern tidal region, with a sand content greater than 70%, benthic diatoms growing on the surface, flat tidal flats, seawater salinity 14-33, no oil pollution and far away from domestic sewage, with a breeding area of ​​12 mu;

[0041] (2) Treatment of breeding grounds

[0042] Mark the breeding area with sticks, every about 200m 2 The area mark is surrounded by a square, and part of the sand in the area is removed to make it slightly lower than the surrounding beach surface. Sandbags and other water-retaining items are used to form a tight circle around the mark around the area. After the tide ebbs, keep the breeding area with water and no dew ;

[0043] (3) Seed sources and specifications

[0044] Purchasing indoor small-sized seedlings bred by Guangxi Ocean Research Institute, seedling size 0.05g-0.06g;

[0045] (4) Int...

Abstract

The invention discloses a high-yield mudflat cultivation method of Sipunculus nudus. The cultivation method of Sipunculus nudus is simple, low in investment and less risky; traditional cultivation in cultivation sea areas is basically a management-free or low-yield cultivation method. Years of efficient mudflat cultivation tests are performed according to physiological living habits of Sipunculus nudus, the steps such as selecting farm conditions, treating farms, selecting fry sources and specifications, raising fry, managing development and harvesting are taken, intensive high-yield mudflat cultivation of Sipunculus nudus is achieved, the cultivation period is a year and half, yield per mu is 280.0-320.3kg, mudflat cultivation yield per mu of Sipunculus nudus is increased greatly, and mudflat resources are fully utilized. The high-yield mudflat cultivation method of Sipunculus nudus is scientific and reasonable in process and highly operable; high-yield cultivation of Sipunculus nudus is achieved by reasonable and efficient use of mudflats.

Description

technical field [0001] The present invention relates to a method for high-yield cultivation of naked square starworm tidal flats ， The invention is suitable for breeding square starworms in coastal tidal flats in southern my country, and belongs to the technical field of aquaculture. Background technique [0002] Naked Checkered Starworm (Sipunculus nudus) Also known as checkered star worms, commonly known as sand worms, belonging to the phylum Astrozoa (Sipucunla), Glycerus (Sipunculus) , shaped like an intestine, long tube-shaped, about 10-20 cm in length, naked and hairless, with lattice-like patterns on the body wall. The naked square star worm is a globally distributed species, and it is distributed in the coastal areas south of Qingdao in my country. Among them, Fujian and Guangdong and Guangxi are rich in resources. It is one of the famous seafood treasures. Foreign markets welcome. This species feeds on tidal flat organic debris and benthic algae. It has a low ...
