Problems solved by technology

This limits the sales cycle of live clamworms and increases the operating risk of live clamworm sellers
At the same time, using the current stocking technology, due to the short survival time of the clamworm, it is limited to carry out related research on the clamworm as the experimental sample.

Embodiment 1

[0030] A kind of double-toothed clam worm indoor circulating water storage method adopts the following steps:

[0031] 1) Storage preparation

[0032] In the storage tank, inject the storage water with a salinity of 26, and the water level is 40cm;

[0033] 2) Circulating water storage and oxygen supply

[0034] Use a circulating water pump to circulate and store water, and control the flow rate of the circulating water body to about 0.005m 3 / h, the hourly water change rate is about 25%; use the aeration pump to maintain the dissolved oxygen content in the storage water always above 10mg / L;

[0035] 2) stocking

[0036] According to the stocking density of 100 / L, the double-toothed clam worms are stocked in the stocking water in the stocking box;

[0037] 3) Bait casting

[0038] Put in powdered shrimp pellet feed filtered through a 60-mesh sieve, with a protein content of 30% to 35%, and the feeding frequency is once every two days, and the single feeding amount is 4g / 1...

Embodiment 2

[0049] According to the method in embodiment 1, select 500 body lengths to be 15-25cm, body color luster, normal vigor healthy double-toothed clamworm, be divided into 5 groups, every group 100, keep 30 days. The temporary care results are as follows:

[0050] Table 1 The results of 30-day storage in indoor circulating water for C.

[0051] death Survival rate % First group 12 88% Second Group 14 86% The third group 15 85% Fourth group 18 82% fifth group 12 88%

[0052] After raising for 30 days, it was found that the survival rate of the double-toothed clam worms raised by this method reached more than 80%.

Abstract

The invention relates to an indoor raising method for perinereis aibuhitensis by circulating water. The method comprises the following steps: 1) preparing for raising; 2) circulating raising water and supplying oxygen; 2) stocking; 3) feeding; 4) controlling a raising environment; and 5) timely sorting out the ill, disabled and weak perinereis aibuhitensis during the raising process. The indoor raising method for the perinereis aibuhitensis by circulating water provided by the invention is formed by improving through adopting a circulating water raising mode on the basis of the perinereis aibuhitensis seawater raising. Under the precondition of ensuring the vigor of the perinereis aibuhitensis, the survival time of the perinereis aibuhitensis is prolonged, and the raising density is increased.

Description

technical field [0001] The invention relates to a method for raising clam worms, in particular to cultivating clam worms indoors using the storage technology of circulating water, belonging to the technical field of marine organism breeding. Background technique [0002] Double-toothed clamworm ( Perinereis aibuhitensis ) belongs to the phylum Annelidae, polychaetes, and Nereidae. It likes to live in caves on calm and nutritious intertidal sandy beaches. It is the dominant species of intertidal muddy beach organisms in China and the main constituent organisms of Chinese offshore marine communities. have important ecological value. [0003] Nereis worm is a high-quality bait for fish, shrimp, crab, etc., and is rich in nutritional value. It is called "universal bait" and has extremely high economic value. At present, the CIF price in the Japanese market is as high as tens of thousands of dollars per ton, and it is also valuable in the Western European market, where the supp...
