Problems solved by technology

[0006] The purpose of the present invention is to provide a method that can ensure a large number of different nereis bodies, high synchronization, and can be adjusted according to production, aiming at the shortcomings of the prior art, such as the small number of different nereis, poor synchronization, and low fertilization rate. Control method of indoor cultivation of Nereis didentate for body maturation and reproduction time

Embodiment 1

[0030] Dongying Zhenyu Aquatic Resources Co., Ltd. has a total of 28 cement ponds with a water body of 40 square meters in the silkworm breeding workshop. In 2010, we collected and raised 500kg of silkworms, and used 10 of the cement ponds. As of July 2011, through the above-mentioned artificial regulation technology, using the presence and timing of sea water drainage and irrigation, etc., a large number of silkworm broods have been successfully induced to mature at the same time, and nearly 1,000 silkworms (including 300 females) have been obtained every day, and high-quality silkworms can be obtained. The number of fertilized eggs reached 200 million. Due to the small number of vacant outdoor earthen ponds, only 400 tons of commercial lugworms were obtained in autumn. From the end of September to the first ten days of October in 2011, targeted harvesting of silkworms was carried out, and nearly 1,500kg of silkworms were stored. The supporting facilities of the silkworms work...

Abstract

A propagation control method for indoor cultivation of Perinereis aibuhitensis is characterized by including the sequential steps of 1, preparing a breeding cement pool; 2, selecting parents of Perinereis aibuhitensis; thirdly, managing ways of breeding outside cages and breeding density; 4, inhibiting propagation of heteronereis; 5, controlling great propagation of heteronereis; 6, performing artificial and natural insemination; and 7, selecting hatching conditions, namely controlling the water temperature at 25 DEG C, hatching to obtain three-setiger juvenile in three days, and cultivating the juvenile. The method has the advantages that a great amount of parents of Perinereis aibuhitensis can be controlled to propagate simultaneously, and juvenile cultivation is arranged designedly; the method is performed in indoor cement ponds and insusceptible to seasons and tides.

Description

technical field [0001] The invention relates to a breeding method for clam worms, in particular to a method for controlling the breeding of clam worms grown indoors. Background technique [0002] Perinereis aibuhitensis belongs to the phylum Annelidae, polychaetes, and Nereidae. It likes to live in burrows on the mud-sand beaches in the intertidal zone with calm seas and rich nutrition. The main constituent organisms of seabed habitats 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 supply exceeds the demand. [0004] The clam worm has the characteristics of large body size and high protein content (70%-80%). It is an important species that can be de...
