Embodiment 1

[0017] 1. Intermediate cultivation of square starworm:

[0018] 1. Conditions for intermediate cultivation ponds: choose a square hard-bottomed cement pond, each with an area of ​​3 mu, and keep the water depth above 100 cm. The water inlet and outlet of the pond are distributed diagonally, and the outlet is lower than the inlet. It can drain the open air, and can also carry out running water cultivation. A layer of medium-fine freshwater river sand is evenly laid on the bottom of the pool, and the average thickness of the sand layer is about 5-10 cm; the water inlet is installed with a water gate net with a mesh of 80-100 mesh; The pond is equipped with a water pump with a power of 2.2 kW;

[0019] 2. Preparation of the intermediate cultivation pond: 20-30 days before the seedlings are released, use the commercially available snail killer "Snail Killer Yu'an" dissolved in water and sprinkle the whole pond to kill snails and other harmful organisms. Use a concentration of 2-5p...

Embodiment 2

[0027] 1. The intermediate cultivation of the square star worm: each step is identical with embodiment 1.

[0028] 2. Cultivation of square starworms:

[0029] 1. Select the cultivation pond of the gridworm: choose a high-level hard-bottomed cement pond with an area of ​​3 to 15 acres, and lay medium-coarse sand with a thickness of 30 to 40 cm at the bottom of the pond; if the sand bottom of the pond is deposited by dead algae, moss, The organic substrate composed of feces, residual bait, sludge, etc. is usually foul-smelling and black. Generally, it is washed 1-2 times with a high-pressure water gun to wash away most of the dust and organic matter in the sand, and the ferocious miscellaneous fish, crabs, etc. are manually removed. ; Sow Penaeus vannamei compound feed No. 1 at an amount of 45-60 kg / mu, and plow it thoroughly to mix the feed and sand evenly, increase the fertility of the sand, expose to the sun for 2-7 days, and store water for 50 cm stand-by;

Abstract

The invention discloses a method for cultivating the sipunculus nudus in a pond. The sipunculus nudus is low in the level of the food chain, is high in stress resistance, is fast in growth, belongs to the local ecological plant formation, is stable in resources group, is high in natural distribution density, small in activities range, and is free of the phenomenon of long-distance migration, thereby being very suitable for the artificial cultivation. However, the current artificial culture is low in survival rate, growth speed and yield. According to the characteristics of the different growth stage of the sipunculus nudus, a proper growth cultivation environment is creased in a nichetargeting way, the pond intermediate cultivation technology of the sipunculus nudus is combined with the pond cultivation technology of the sipunculus nudus, the survival rate of the seeds is improved, the seedling quantity per unit area is increased, the artificial breeding quality is guaranteed, and the cultivating survival rate and the cultivating per unit yield are improved, so that the cultivating survival rate reaches at 85%, the cultivating per unit yield reaches at 215kg / mu, and the aim of the high-efficiency cultivation of the sipunculus nudus is realized.

Description

technical field [0001] The invention relates to a method for cultivating the square star worm in a pond, and belongs to the technical field of seawater cultivation. Background technique [0002] Sipunculus nudus, also known as naked square star worm or naked square star worm, commonly known as "sand worm", belongs to the genus Spunculus nudus of the phylum Astrozoa. The gridworm is a species widely distributed in the warm water world. It is widely distributed along the coasts of the three oceans. It lives in caves. It inhabits estuaries, harbors and sandy or sandy mudflats with rich surface runoff. It mainly feeds on benthic algae and organic debris. Crumbs are distributed along the coasts of Fujian, Guangdong, Guangxi, Hainan and Taiwan in my country, among which the sea area of ​​Guangxi has the most abundant resources. Judging from the characteristics of the species, the food chain of the gridworm is low, strong in stress resistance, and fast in growth. In addition, the ...
