Problems solved by technology

However, since estuaries and tidal flats are open natural environments, the growth of lugworms is limited by the natural climate and environment.
[0005] (2) The seedlings of clamworm come from natural reproduction, rely heavily on the marine environment, and the actual survival rate of clamworm larvae is low
[0006] (3) Nereis worm has many harmful organisms, and it is impossible to effectively control the harmful organisms in the natural environment
[0007] (4) The yield per unit area of ​​clam worms cultured in shrimp ponds and tidal flats is low, which is greatly affected by the climate
At the same time, there is currently no report on artificial indoor intensive cultivation of clam worms

Embodiment 1

[0045] a. Built-in aquaculture pond, the specifications are: 6-8 meters long, 2-4 meters wide, 1.0 meters high, the bottom of the pond has a thickness of 20-50cm, and the seawater layer is 30-50cm high;

[0046] b. Both the fine sand and silt sand for substrate are commercially available construction sand, which is obtained by sieving through a sieve with a pore size of 0.2 to 1 mm. The sand and sand are matched in a ratio of 1:1. Among them, coarse sand (particle size 2~0.5mm): 15%; medium sand (particle size 0.5~0.25mm): 25%; fine sand (particle size 0.25~0.063mm): 10%, coarse silt (particle size 0.063) ~0.016mm) 35%; fine powder sand (particle size 0.016~0.004mm) 15%. The thickness of the substrate is 10-30cm. The sediment is soaked in 5-10ppm chlorine dioxide solution for 24 hours for disinfection. After disinfection, the sediment is cleaned by sea water for 24 hours.

[0047] c. Put artificially cultivated sand silkworm seedlings, the specification is 0.2~1g / piece, the seedli...

Embodiment 2

[0053] Others are the same as in Example 1. If bacterial diseases occur on a large scale during the breeding of silkworms, the treatment method for disease treatment is to sprinkle penicillin (5-8ppm) in the whole pond for 5-7 days, and use the sediment with a concentration of 10-20ppm. The bleach is disinfected. After 24 hours, use fresh sand and filter seawater to wash thoroughly.

Abstract

The prevent invention provides full artificial controlling culture environment a method for achieving high density intensive artificial culture of clamworm in indoors. This method is according to clamworm living characteristics to build culture pond, collocate sediment and rear with artificial diet, to make clamworm suit for culturing in indoors and without the limit of climatic environment, aquaculture production can be carried out throughout the year. To compare with existing clamworm culture mode, this method ensures high survival rate and high growth rate of clamworm seedlings. To adopt this method to culture clamworms, the survival rate reaches 70 percent to 90 percent, the weight of finished clamworm is 5 to 10 gram. The annual average yield of grub increases 2 to 3 gram, and supplying living clamworms for export the whole year.

Description

Technical field [0001] The invention relates to a breeding method of sand silkworms, in particular to an indoor artificial intensive breeding method. Background technique [0002] Sandworm (Perineries aibuhitensis Grube) belongs to the phylum Annelid, Polychaete. It is the dominant polychaete in the coastal beaches of our country, and it is also a high-quality polychaete with high economic value. Among them, the export FOB price of double-toothed sandworms and multi-toothed sandworms reached 18 US dollars / kg. The sand silkworms in Liaoning have a high reputation in the export of sand silkworms due to their large individual size, low water content, and green color. In recent years, due to over-harvesting, the natural resources of sand silkworms have been exhausted. The artificial breeding of sand silkworms can provide an effective way for the supplement, sustainable use and protection of polychaete sand silkworm resources in my country, thereby creating good economic benefits and ...
