Abstract

The invention discloses a three-dimensional pool cultivating method of portunus trituberculatus. The method is characterized in that: a fine sand layer with thickness of 10-20 cm is paved locally at the bottom of a pool, thus portunus trituberculatus can hide better so as to reduce mutual massacre; the fine sand layer at the cement pool bottom can be used for a long time; a plastic film is firstly paved and then fine sand is paved on the mud pool bottom so as to achieve the long-time use purpose, thus the cost is lower than that of massacre prevention sheets, the fine sand layer is not covered by mud, and the mutual massacre preventing effect is better; a cultivating basket is arranged in the upper-layer water body of the cultivating pool, and the mixed cultivation in the cultivating pool and independent cultivation in the cultivation basket are combined, thus the utilization rate of the water body in the cultivating pool is higher, the mu yield is higher and the cultivating benefit is improved; and a shielding shed is arranged above the cultivating pool, thus the sun insolation and rainstorm attacking are prevented, the actions of cooling, shielding light and preventing sudden change of salinity are exerted, and the survival environment of portunus trituberculatus is stable. Therefore, the method disclosed by the invention is a portunus trituberculatus three-dimensional cultivation method which has the characteristics of good hiding effect, lower cultivating cost and higher cultivating benefit and can be used for a long time.

Description

Portunus trituberculatus Miers three-dimensional pond breeding method

Technical field

The present invention relates to the Portunus trituberculatus Miers cultural technique, be specifically related to Portunus trituberculatus Miers three-dimensional pond breeding method.

Background technology

The Portunus trituberculatus Miers breed comprises the beach enclosure culture, net enclosure culture, raises in cages and pond culture, and the breed pond of pond culture can be built in outdoor, also can build in indoor; Culture the pond and can be Tu Chi; Also can be cement pit, at the bottom of the pond of Tu Chi be the shale pond at the bottom of, at the bottom of the pond of cement pit be cement pit at the bottom of.Breeding process comprise support before regulation, feedstuff feeding, oxygenation, change water, remove contamination and disease control etc.Like publication number is CN101790965; Name is called the application for a patent for invention of the artificial cultivating method of Portunus trituberculatus Miers, and just disclosing at the bottom of the pond is the method for the native pool cultivated Portunus trituberculatus Miers on shale ground, the regulation and control of this method through increasing with temperature rising quantity of exchanged water; Composite microorganism viable bacteria agent regulation and control water quality; The feed of throwing something and feeding increases with body weight and reduces, be provided with at the bottom of the pond anti-relic be beneficial to hidden with prevent the technology of cutting one another's throats, reach the purpose that improves survival rate, improves output.Though anti-relic can make that Portunus trituberculatus Miers is hidden to cut one another's throats with minimizing in this method, anti-relic is more expensive, and aquaculture cost is higher, and can not fundamentally avoid cutting one another's throats between individuality, and it is lower to culture survival rate.

Summary of the invention

Technical problem to be solved by this invention provides a kind of Portunus trituberculatus Miers three dimensional-breeding method that improves pond culture survival rate and culture benefit; This method is that Portunus trituberculatus Miers is cultured to the developing a kind of interim form of batch production; Has output value height; Cost is lower, can make full use of advantages such as water body and soil.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: Portunus trituberculatus Miers three-dimensional pond breeding method comprises the steps:

1, in the breed pond at the bottom of the shale pond or at the bottom of the cement pit, be covered with the fine sand layer of 10-20 centimetre of thickness at the bottom of the pond on the 1/3-2/3 surface, be provided with plastic foil at the bottom of the shale pond and between the fine sand layer;

2, the dark 0.5-2 rice of culturing pool; Culture and to be provided with one deck in the water body at the middle and upper levels in pond and to have the grid type of lid to culture basket, the length and width that said grid type is cultured basket be 25-40 centimetre with height, and this grid type is cultured and is provided with length and width and height in the basket is 10-15 centimetre undercovert; Fill the fine sand of 10-15 centimetre of thickness in the said undercovert; Culture the juvenile crab of 2 or 3 phases of raising scattered in the pond, it is 1500-2000/mu that juvenile crab is raised density scattered, and monoculture has the juvenile crab of 5-10 grammes per square metre in the said grid type breed basket;

3, said breed pond is provided with shade.

The breeding water in this breed pond is the filtering sea after seawater process deposition and the filtration.After breeding water was handled through husky filter, water quality was limpid, and it is higher to form quality.

Culture the regulation of preceding pond, feedstuff feeding, oxygenation in the breeding process, change water, remove contamination and disease control etc. is managed by conventional method, do not specify at this.

Compared with prior art, the invention has the advantages that Portunus trituberculatus Miers three-dimensional pond breeding method, through the local fine sand layer of laying 10-20 centimetre of thickness at the bottom of the pond; Can let Portunus trituberculatus Miers better hidden, minimizing cuts one another's throats, at the bottom of the cement pit on the fine sand layer can use for a long time; First plastic covering film repaves fine sand at the bottom of the shale pond, can reach the purpose of long-term use, and cost is lower than anti-relic like this; Can do not covered by shale again, the anti-effect that cuts one another's throats is better; The upper strata water body of culturing the pond is provided with cultures basket, cultures and raises scattered in the pond and culture a basket monoculture and combines, and culturing pool body availability is higher, and per mu yield is higher, the culture benefit raising.Culture the pond and be provided with shade, can prevent that sunlight is exposed to the sun and heavy rain attacks, play cooling, shading and prevent the effect of salinity cataclysm, make the Portunus trituberculatus Miers living environment stable.Therefore the present invention is that a kind of hidden effect is better, can use for a long time, and aquaculture cost is lower, the cultural method of the Portunus trituberculatus Miers three-dimensional that culture benefit is higher.
