Problems solved by technology

At present, seedling cultivation largely depends on naturally mature groups. In a specific season, the bodies of Heteresis worms from nature are harvested for breeding. The seasonality is strong, and it is controlled by the tide and is uncontrollable. It is very important for arranging production and large-scale seedling cultivation. unfavorable
[0004] At present, the common breeding method of Nereis didentate, whether it is fishing natur...

Embodiment 1

[0023] We have a total of 28 cement ponds with a water body of 40 square meters in the silkworm breeding workshop of a certain aquatic resources company in Dongying. In October 2012, we collected and raised 1500kg of silkworms, and 26 of them were put into use. Until December 6, 2012, through the above-mentioned temperature control technology, the temperature is controlled until February 6, 2013, and the heating is stopped. As of March 6, 2013, a small amount of worms were found to be floating. Due to the low temperature in the outdoor earthen pond, no productive breeding work was carried out. On March 20, 2013, the natural water temperature rose, and productive breeding began. By adding seawater, nearly 1,000 parent silkworms (including 300 females) can be obtained every day, and 200 million high-quality fertilized eggs can be obtained. After hatching, the larvae enter the earthen pond in the outdoor greenhouse for early seedling cultivation. In April 2013, nearly 2,000 silk...

Abstract

A control method for indoor early propagation 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, performing daily winter management; and 5, after temperature control, restoring natural water temperature, namely continuing temperature control 30-40 days after normal low-temperature period, and keeping the indoor temperature at about 25 DEG C so that mature heteronereis can be found in about one week. The method has the advantages the method is performed in indoor cement pools and insusceptible to seasons and tides; simultaneous propagation of a great amount of parents can be extended to mid-March, and juvenile cultivation can be arranged in the first half year designedly; through the control way of artificial heating, cultivation is 3 months ahead, and fertility rate and hatching rate are the same as those of Perinereis aibuhitensis calculated in normal seasons; and the method is suitable for industrial production of juvenile of Perinereis aibuhitensis.

Description

technical field [0001] The invention relates to a method for regulating the early breeding of clam worms, in particular to a method for regulating the early breeding of clam worms indoors. Background technique [0002] 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. 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] The clam worm has the characteristics of large body size and high protein content (70%-80%). It is an important species ...
