Description

A kind of crab cultural method
Technical field
The present invention relates to aquaculture field, specifically a kind of crab cultural method.
Background technology
The crab of nature growth is liked living in the rich rivers and lakes of water cleaning, pasture and water, as people are to open country The extensive seizure of outer crab, field crab yield is fewer and fewer, but eater pursues the green and healthy clean of field crab, Therefore, a kind of cultural method of the crab close in natural growing environment should be set up.
The content of the invention
In order to solve the above problems, the present invention proposes a kind of crab cultural method.
A kind of crab cultural method, it is comprised the following steps that:
(1) the standby pool:The intensive culture pool is done in the pond for selecting one piece of 3-5 mu, and waterweed is planted in pond, the lid greenhouse on pond Waterweed is covered, is heated simultaneously, is supplied oxygen;
(2) juvenile crab is thrown:After the ready 2-3 in the intensive culture pool months, prepare another piece of pond along the river long, launch juvenile crab and Feed, and temperature control, oxygen supply;
(3) growth promoting:After 2-3 months, in the pond of step (2), heating, oxygenation, and increase feeding for feed;
(4) shift:After the free-ranging of 2-3 months, enter in the intensive culture pool that the crab in step (3) is transferred in step (1) Row fine-grained management;
(5) manage:Pasture and water are planted in the intensive culture pool, launch spiral shell, while regularly replace cultivation water, carry out becoming more meticulous for crab Raising.
Temperature control in described step (2) throwing juvenile crab is at 19 DEG C -22 DEG C.
Oxygenation, heating, increase feed supply are grown in advance in order that obtaining crab in described step (3) growth promoting.
Being replaced by every 3 days for cultivation water is changed once in described step (5) management, changes the 20% of water every time.
The beneficial effects of the invention are as follows:Double pool patterns cultivate crab, convenient to plant pasture and water, there is provided feed;Fine-grained management, Spiral shell is thrown, pasture and water is planted, changes cultivation water, is grown beneficial to crab green;The waterweed of Planting Fast-growing, high yield, waterweed is as a kind of Submerged plant, it is nutritious, body eutrophication can be prevented, substantial amounts of oxygen can be released during photosynthesis, can also be inhaled Constantly caused largely harmful ammoniacal nitrogen, carbon dioxide and molten lost articles of remaining bait and some organic decomposition things in water are received, only Change water quality, help to build good aquatic environment.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, below it is right The present invention is expanded on further.
Embodiment:
A kind of crab cultural method, it is comprised the following steps that:
(1) the standby pool:The intensive culture pool is done in the pond for selecting one piece of 3-5 mu, and waterweed is planted in pond, the lid greenhouse on pond Waterweed is covered, is heated simultaneously, is supplied oxygen;
(2) juvenile crab is thrown:After the ready 2-3 in the intensive culture pool months, prepare another piece of pond along the river long, launch juvenile crab and Feed, and temperature control, oxygen supply;
(3) growth promoting:After 2-3 months, in the pond of step (2), heating, oxygenation, and increase feeding for feed;
(4) shift:After the free-ranging of 2-3 months, enter in the intensive culture pool that the crab in step (3) is transferred in step (1) Row fine-grained management;
(5) manage:Pasture and water are planted in the intensive culture pool, launch spiral shell, while regularly replace cultivation water, carry out becoming more meticulous for crab Raising.
Temperature control in described step (2) throwing juvenile crab is at 19 DEG C -22 DEG C.
Oxygenation, heating, increase feed supply are grown in advance in order that obtaining crab in described step (3) growth promoting.
Being replaced by every 3 days for cultivation water is changed once in described step (5) management, changes the 20% of water every time.
The preparation on the described intensive culture pool is in December;The pool is separately set when January and launches seedling;In the 3-4 months, increase is raised Material, temperature raising oxygenation, promotes crab to grow up, and starts free-ranging;At July, crab is transferred to the intensive culture pool and carries out fine-grained management.
Described waterweed it is nutritious, dry accounts for 8.23%, crude protein 2.1%, crude fat 0.19%, nothing Nitrogen extract is 2.53%, and cinder is divided into 1.52%, crude fibre 1.9%;Rich in vitamin C, dimension life in its cauline leaf and coring Plain E and vitamin B12 etc., this, which can be supplemented, feeds cereal and the multivitamin deficiency of other feeds, also containing abundant calcium, The content of phosphorus and various trace elements, wherein calcium is especially prominent;Waterweed contains 1.9% crude fibre, and this contributes to river crab pair The digestion and absorption of a variety of foods;River crab is fed with waterweed, palatability is preferable, and river crab growth is fast, and feed coefficient is low, can save Concentrated feed 30% or so, feeding herbivorous fishes save concentrated feed 50% or so.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry For personnel it should be appreciated that the present invention is not limited to the above embodiments, that described in above-described embodiment and specification is the present invention Principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these change and Improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent Thing defines.
