Description
Technical field
The present invention relates to technical field of aquaculture, and in particular to the method that a kind of high density set in river crab pond supports mandarin fish.
Background technology
It is a kind of common aquaculture model that river crab pool set, which supports freshwater shrimp, and only a small amount of set supports mandarin fish, is mainly used for eliminating wild miscellaneous
Fish, due to not being that master supports kind, usual raiser not too much takes notice of in management.But Guiping City aquatic farm is quick by its
Sharp market smell, reforms stocking model, is not reducing on the basis of river crab puts quantity in a suitable place to breed, is courageously being attributed in the river crab pool
High density set support, river crab and mandarin fish is all achieved original yield, economic benefits.Foster mandarin fish is covered in river crab pond can
To make full use of food resource and water space, the purpose of increasing both production and income is reached.Also, due to river crab, mandarin fish breeding environment base
Originally it is consistent, it is not necessary to increase auxiliary facility, as long as delivering appropriate big specification mandarin fish kind, so that it may reach and increase income purpose.But river crab
Pool set supports mandarin fish and still has some shortcomings, and such as water body, efficiency of feed utilization be not high, and ratio for input and output value is relatively low.
The content of the invention
The deficiency existed for above-mentioned technology, the present invention provides a kind of river crab pond high density method that set supports mandarin fish, real
The efficient mated combination of existing two kinds of high-quality aquatic products, effectively improves water body, efficiency of feed utilization, improves ratio for input and output value, significantly
Improve the economic benefit of pond culture of Chinese mitten crab.
To achieve these goals, the present invention provides following technical scheme, carries out in the following manner：
（1）Pond is sterilized except becoming silted up：Water is drained first, is exposed to the sun 25-30 days, the mud in pond is then excavated with machinery, keeps becoming silted up
Mud thickness 5-19cm, and it is organized into 6 pools mouthful, useful storage depth 2m with dredging machine soil-shifting；Intake 0.1 meter after the completion of arrangement
Deep, the every mu of full pond that added water with 100-120kg quick limes, which is sprinkled, pours sterilization and cleans up the pond, and is filled within the 5th day after cleaning up the pond 0.5m deep；Maintenance is whole
The Ping Chi ridge, it is ensured that enough shallow water areas supply river crab feeding activity；
（2）Facility is equipped with：
1. electromechanical configuration：Every pool mouthful is equipped with water pump and each 2 of paddle aerator, peace in diagonal distribution
The purpose of holding water pump is to promote water to circulate；Micro-pore oxygenation machine is equipped with by 0.3kw/ mus of standards, and is set in the pool
Bar formula aeration tube is put, every pool mouthful is equipped with 1 device for feeding fish bait, be mainly used in supplement after October and feed feed of grass carp；
2. anti-escape device：The domatic upside calcium-plastic board of surrounding on every pool mouthful sets the river that height is 0.5 m
Crab escape-proof fence；Every pool mouthful sets a height of 1.2 m, long 60 m, wide 60 m plastics in place 10 meters remote away from pool side
Purse seine；The river crab that early stage puts in a suitable place to breed concentrates grain bin to be put on the outside of purse seine, keeps apart with eel grass planting area, it is to avoid it is tender that it bites eel grass broken
Bud, influences the normal growth of eel grass；
（3）Cultivate foundation bait：
1. the storage excrement that becomes thoroughly decomposed that first every mu applies 80-100 kilograms before plantation pasture and water, plants and gradually fill water after pasture and water again mid-March,
The depth of water is controlled in 30-40cm；Inner side being enclosed in net at the beginning of 5 months and broadcasting sowing eel grass seed, every mu of sowing quantity is 0.5kg；At the beginning of 6 months and at the beginning of 7 months
Each to apply 1 secondary organic fertilizer, consumption is 4 kg/ time；Promote pasture and water growth for rich water；
2. pasture and water plantation terminate it is rear every mu dispensing the ages in winter of 2-3kg bis- crucian, it is therefore an objective to for mandarin fish provide enrich fish bait and
The total amount of pasture and water in the pool is reduced, is mitigated and is manually cradled the labor intensity of pasture and water and avoid impacting river crab normal growth；4
Every mu of the beginning of the month delivers spiral shell 450-550kg living, it is therefore an objective to i.e. as the high-quality animal feed of river crab, and absorption water body fertilizer is played again
Degree, the effect purified water；
（4）Seed is delivered：1. start to deliver river crab in March, specification is 150-170/kg, and every mu is delivered 400-500 only；②
Start May to deliver mandarin fish seedling, specification is 3-4cm, before delivering first with 3% salt water sterilization 5min, every mu covers foster 80-100
Tail；
（5）Feeding management：River crab put in a suitable place to breed initial stage feed be fresh small fish and pellet, mid-term be pellet collocation corn,
Wheat, pumpkin, the later stage are small fish, particulate material collocation greenfeed；
（6）Regulating and controlling water quality：1. note renews water：Water filling in 5-7 days once, changes water for 15-20 days once, and 10-20 centimeters of water is changed every time；②
Water transfer：Regulating water quality pH value is in 7.5-8.5, since June, adjusts running water matter using 1 microorganism formulation within every 15 days；③
Oxygenation：Oxygen increasing equipment is started since June, is switched on the pump simultaneously, daily running time is 4-24h；
（7）Disease control：It is by the end of May and each by the end of September with 1 sulphoxylic acid zinc prevention balantidiasis；Mid-August and the last ten-days period in September respectively use 1
Secondary disinfection agent of chlorine dioxide；Since being added June every 15 days in mandarin fish bait and crab feed with 1% amount of forage volume
Three blooms and Radix Isatidis, it is continuous every time to add 3~5 days.
Further, the step（2）Pump power be 3 kw, paddle aerator power be 2.5kw.
Further, the step（3）Pasture and water kind be waterweed.
Further, the step（3）The planting patterns of pasture and water be：Using the method for cutting stem segmentation, on every pool mouthful
The net of interior setting encloses cuttage in outside and shallow ridges and planted, and line space is 2m, and spacing in the rows is 0.5m, and distribution area accounts for the 2/ of full pool area
3。
Further, the step（5）The feedstuff feeding time be daily 14 when first throw mandarin fish bait, fed again when 17
Crab feed.
Further, the step（6）Regulating water quality pH mode is：Using quick lime, per two weeks to one month one
It is secondary, per consumption 14-16kg.
Further, the step（6）Microorganism formulation for photosynthetic bacteria, nitrobacteria, one kind of bacillus or
It is several.
In summary, the present invention has the advantages that as a result of such scheme：
1st, Polyculture is new.Raised together with the matching of special aquatic products kind, set supports conventional fingerling, can be filled with three-dimension use Water space
Point using the mutual facilitation between different fingerlings, both can purifying water body, specific yield can be effectively improved again.
2nd, high financial profit.Because river crab, mandarin fish breeding environment are consistent substantially, it is not necessary to increase auxiliary facility, as long as throwing
Put appropriate big specification mandarin fish kind, so that it may reach and increase income purpose.Special pool high-density breeding hair is greatly reduced using Polyculture
The high risk of sick rate, is greatly reduced production cost, increases economic efficiency.
3rd, ecological environment is good.Using happy algae and propagation spiral shell is planted in pond, pond water quality can be both purified, but also as river
Crab feed, is a kind of environmentally friendly Eco-breeding pattern.
Embodiment
With reference to embodiment, the present invention is described further.
