Embodiment 1

[0020] On May 20, 2010, artificial indoor cultivation was carried out on the broodstock collected from wild populations, and the cultivation time was 45 days. The specific implementation steps:

[0021] (1) Construction of indoor cultivation ponds: 2 industrialized indoor cultivation ponds, square, with a bottom area of ​​10 m 2 , 1.2m deep, the inlet and outlet pipes are distributed diagonally, and the pipe is used to add water near the outlet when entering water. The 1 / 4 near the drain is a sand-free area, and the remaining 3 / 4 is a broodstock layer. The middle is separated by horizontally stacked building bricks to separate the sand layer. The thickness of the bricks is about 35cm, and the brick seal is about 1cm. The bottom of the broodstock cultivation layer is paved with gravel with a particle size of 3-7 mm, and the thickness is about 5 cm. The upper part of the gravel layer is covered with a 50-mesh screen, and the partition bricks are wrapped to prevent the sand from ...

Embodiment 2

[0029] On June 20, 2011 and August 14, 2011, wild and cultured populations were mixed to collect broodstock, and artificial indoor cultivation was carried out. The cultivation time was 40 days. The specific implementation steps:

[0030] (1) Indoor cultivation pond construction: indoor cement pond, square, with a bottom area of ​​15 m 2 , 1m deep, the inlet and outlet pipes are distributed diagonally, and the conduit is used to add water near the outlet when entering water. The 1 / 4 near the drain is a sand-free layer, and the remaining 3 / 4 is a parent-culture layer. The middle is separated by horizontally stacked building bricks to separate the sand layer. The thickness of the bricks is about 35cm, and the brick seal is about 1cm. The bottom of the broodstock cultivation layer is paved with gravel with a particle size of 3-7 mm, and the thickness is about 5 cm. The upper part of the gravel layer is covered with a 50-mesh screen, and the partition bricks are wrapped to prevent ...

Abstract

The invention discloses a method for breeding a sipunculus nudus parent. Artificial breeding of sipunculus nudus is high in cost, very instable in effect and significantly relevant to poor artificial spawning effect, high mortality and inconsistent egg laying quality of the sipunculus nudus parent. Meanwhile, mismatch of the yield is caused due to excessive concentration of egg laying in induced spawning, leading to resource waste. By adopting the measures of building of a sipunculus nudus parent breeding pond, indoor artificial food culture, maturing and breeding management, disease control and prevention and artificial control of egg laying, the mortality is lowered to 7-12 percent within 40 days of artificial indoor parent maturing and egg laying breeding, the single yield of an individual parent of 20g is 50,000-70,000 eggs, the metamosphsis rate of hatched larvae is 13-86 percent, and artificial control of egg laying can be performed according to the production capacity. By adopting the method, the source and controllability of fertilized eggs are realized in plant artificial breeding and selective breeding of the sipunculus nudus, the egg laying time of the parent is prolonged, and the breeding cost is saved.

Description

technical field [0001] The invention relates to a method for indoor broodstock cultivation of phalaenopsis, which is suitable for indoor artificial cultivation and controlled oviposition of broodstock for industrialized seedling cultivation and fine-bred selection of phalaenopsis in the coastal areas of southern China, and belongs to the technical field of marine aquaculture. Background technique [0002] Sipunculus nudus, also known as the nude square starworm, commonly known as sandworm, belongs to the genus Astrozoa, and is a species widely distributed in the warm water world. It is distributed in the south of Qingdao, my country . The square star worm has a low food chain level, strong resistance to stress, and fast growth. The square star worm belongs to the local ecological group, the resource group is stable, the natural distribution density is high, the activity range is small, and there is no long-distance migration and migration. In a 200-300-mu harbor-enclosed sh...
