Description
Technical field
The invention belongs to crab cultivation fields, and in particular to detain juvenile crab breeding method in rice field.
Background technique
Currently, the market demand of big specification river crab is increasing, culture efficiency is significantly better than small river crab.It cultivates
The cultivation of big specification river crab, high-quality button crab is particularly important.And it detains crab and cultivates the environmental condition of quality and pond, seed source, puts
Support density, feeding management and crab disease prevention and treatment etc. many factors it is closely related.Only each factor reasonable combination, could high yield and steady
It produces.
Megalops larva cultivates the main path that button crab has become current culture of Chinese mitten crab seed source, and various regions are all being tried to explore
The higher method for improving cultivating survival rate, control specification, controlling sex premature ratio, especially sex premature ratio are always to perplex to support
A problem at family is grown, people generally control sex premature ratio by increasing the measures such as throw-in density, control bait throwing in, control water temperature
Example.But still without solution fundamental issue.
Summary of the invention
The object of the present invention is to provide a kind of rice fields to detain juvenile crab breeding method, low, young to solve button juvenile crab cultivating survival rate
The inferior problem of crab overcomes the shortcomings of present in tradition button crab method for culturing seedlings.
The purpose of foregoing invention, is realized by following technical proposals: a kind of rice field button juvenile crab breeding method, including walks as follows
It is rapid:
(1) aquaculture pond prepares: in rice field, surrounding is arranged anti-escape wall and excavates circular groove, and the width of circular groove is 2-2.5m, and ditch depth is
0.8-1m opens a lead at interval of 6-8m among rice field, furrow width 1.5m, and deep 0.6m is equipped with into pumping equipment；Per acre with life
Lime 80-100kg carries out disinfection, and pond is shone after disinfection 7-15 days；Culture water quality is carried out within 15 days before putting seedling, is intake for the first time deep
0.5m is allowed to dry after 1 day, shines pond 3 days；2nd water inlet depth 0.4m, and noon on the same day applies compound fertilizer in field, 20 jin per acre, applies
With water after compound fertilizer 4-5 days in planting water peanut, one plant of 6-8 rice in field after yellow green or tea green；
(2) megalops larva is put in a suitable place to breed: disposably putting megalopa stage in a suitable place to breed into rice field in 2 kgs/acre of ratio at the beginning of 5 months
Young crab；
(3) feedstuff feeding: the bait of megalops larva is put based on free feeding water plant and cultivation wheel animalcule in megalops larva
Rice field is supported after 10 days, daily in fixed position and time feeding material, foodstuff is beans sauce and expects naturally that beans sauce is by soybeans soaking
It is cooked after grinding and is prepared, material is phytoplankton, zooplankter and zoobenthos naturally；
(4) water quality and substrate regulate and control: every application in 10 days quick lime 1 time, quick lime dosage is 10g/m3；It was applied every 20 days
Each primary with photosynthetic bacteria and nitrobacteria, photosynthetic bacteria dosage is 2g photosynthetic bacteria/m3Water body, nitrobacteria dosage are
0.1mL nitrobacteria stoste/m3Water body keeps water transparency in 30cm-50cm；Remain molten in water by nano oxygen enriching equipment
Oxygen content is solved in 4mg/L；Depth of water 0.5m was kept before the first tenday period of a month in May, was changed every 5 days 5- March next year water 1 time；
(5) it young crab harvest: is caught in December current year and the next year 1-3 month.
Further, bleaching powder soaking disinfection is used before water peanut transplanting in the step (1), when plantation will keep the depth of water
30cm or more.
Further, the anti-escape high 40-60cm of wall in the step (1) is glass reinforced plastic using material.
Further, the specification of megalops larva children crab is 120,000/kg in the step (2).
Further, day feeding volume is the 5% of crab weight in the step (3).
Further, each quantity of exchanged water is to cultivate water 1/4-1/3 in the step (4).
Further, nano oxygen enriching device model is LC-CNR-65 in the step (4), and manufacturer is that Guangzhou is green clear
Environmental protection equipment Co., Ltd.
Compared with prior art, the invention has the following beneficial effects: photosynthetic bacteria and nitrification are applied after spray agricultural climate condition for corn
Bacterium simultaneously maintains content of oxygen dissolved in water by nano oxygen enriching equipment, can be improved the oxygen content and cleanliness of water, improves big
Eye larvae survival rate and yield, while the breeding of disinfect pathogen can be inhibited；By feed in set time, fixed dosage, fixed product
Matter and fixed position are launched, and have ensured the equilibrium of nutrition necessary to megalops larva, avoid a part of individual small or constitution weak
Strive less than feed and cause to cut one another's throat, improve survival rate of seedling, may advantageously facilitate crab movement seek food, improve its be immunized
Power, moreover it is possible to avoid the excess of feed from feeding polluted-water, it is easy to clean；Rapid growth stage is fed in the early stage, can satisfy big
The eye young rapidly grows required a large number of nutrients；The method of the present invention can be improved the survival rate of megalops larva, megalops larva
Development is fast, specification is big, yield is high, sex premature rate is low, and manageability, has cultivation promotional value well.
Specific embodiment
It is right below in conjunction with the embodiment of the present invention to keep the purposes, technical schemes and advantages of the invention implemented clearer
Technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of the invention

Comparative example 1 is button juvenile crab routine breeding method.
Comparative example 2 is the difference from embodiment 1 is that be not used photosynthetic bacteria and nitrobacteria.
Comparative example 3 is the difference from embodiment 1 is that using commercially available river crab pellet, and using conventional feeding method.
Crab harvest situation is buckled under 1 different disposal of table
| Processing | Survival rate (%) | Mu harvest weight (kg) |
| Comparative example 1 | 63.2 | 134.7 |
| Embodiment 1 | 78.7 | 150.1 |
| Embodiment 2 | 73.4 | 142.9 |
| Embodiment 3 | 79.7 | 151.9 |
| Embodiment 4 | 77.2 | 145.1 |

| Comparative example 2 | 62.5 | 131.8 |
| Comparative example 3 | 67.2 | 139.2 |
From the data in table 1, it can be seen that the survival rate of button crab is between 62.5%-79.7% under the conditions of the present invention, mu harvest weight
For amount between 131.8kg-151.9kg, comparative example 1-3 detains the survival rate of crab between 62.5%-67.2%, and mu harvest weight exists
Between 131.8kg-139.2kg.The rice field button crab cultivated by the method for the invention, caused by effective solution is because of kind of Geological Problems
At the undesirable problem of button crab cultivation specification, and then improve the economic benefit of button crab cultivation.And this method implements simple, button crab rule
Lattice are significantly greater than the button crab of common breeding method.
