Abstract
The invention discloses a kind of freshwater aquiculture technology of prawn, the prawn culturing early stage is fed 2 times daily, i.e., when 8,20 when feed；Cultivation mid-term feed daily 3 times, i.e., when 8,19 when, 23 when feed；Cultivation the later stage feed 4 times daily, i.e., when 7,12 when, 19 when, 0 when feed.Early stage day feeding volume is the 8.1% of shrimp gross weight, and mid-term is 6.8%, and the later stage is 4% 5%.Uniformly splashed at the side of a pond when feeding, night feeding volume, which is accounted for, feeds the 50% of total amount day, and beneficial features of the invention are：Fertility is strong, and growth is fast, high efficiency.
Description
Technical field
The present invention relates to cultural technique field, the freshwater aquiculture technology of more particularly to a kind of prawn.
Background technology
General cultured prawn is：One class is that, into the seawater included using power, such seawater is polluted due to sea area by tidal range
It is increasingly serious, it is many containing bacterium, virus and harmful chemical in seawater, intake again after first should being handled through cistern；It is another kind of
It is direct groundwater abstraction, can avoids bringing cause of disease into, but the chemical analysis of different regions underground water is different, such as：Ammonia nitrogen, Asia
Nitrate or sulfide content are higher, and pond must can be entered after treatment, otherwise can influence survival rate and the growth of prawn
Speed.Its processing method is abundant aeration, increases oxygenation amount, and the microorganism formulations such as photosynthetic bacteria, nitrobacteria are used in combination
Processing.In desalinized farming area, it is also noted that the pollution condition of water source of fresh water.
The content of the invention
The technical problem to be solved in the present invention is to overcome existing defect there is provided a kind of freshwater aquiculture technology of prawn.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme：
1st, place election physical features is flat, and substrate is preferably shale or argillo arenaceous, simultaneously, it is desirable to which extra large, light water intaking is convenient, water
Matter is pure and fresh pollution-free.Meanwhile, there should be the supply of electric power of abundance.It is required that bottom of pond is flat, mud can not be blocked up.
2nd, shrimp ponds are built
(1) shape：Circular or close to circle shrimp ponds are preferred, and in the case where increasing the machine of supporting effect, water can form circulation, favorably
Suspension waste collects exclusion to pond center in water.But to improve land utilization ratio, most shrimp ponds are still built as rectangle or just
It is square.
(2) area：Condition it is good build great Chi.General area is 10-20 mu, condition it is poor build up little Chi, general face
3-5 mus of product, is easy to management.
(3) bottom of pond：Bottom of pond is smooth, compacting, and mulch film bedding can be used when having ready conditions.Bottom slightly should be tilted in pan bottom shape to center,
And drainage pipeline is set in bottom of pond center, it is easy to blowdown and drains water.
(4) depth：Chi Shen is generally 2-2.5 meters, depth of water 1.5-2 meters after water inlet.Depth of water breeding density is big.
(5) cistern：Pond is built in the place for having pollution at water source, and the retaining of respective area should be set to handle.
3rd, clean up the pond and remove the evil
The shrimp pool is after per season harvests, and bottom of pond, which accumulates substantial amounts of mud, excrement, residual bait, spoil and canebreak etc., to be had
Machine thing, is to cause the aging of the shrimp pool, water quality to ruin and induce the major reason of prawn disease.Therefore, must thoroughly it be subject to before putting in a suitable place to breed clear
Remove.Typically manually or mechanical system roots out surface mud.After desilting, every mu of full pond float of 75-100 kilograms of quick lime.
4th, the selection of shrimp seedling
Selection standard：Health young shrimp body surface cleaning is glossy, and the complete tail fan of limb foot is separated, and shrimp body is without bleaching, redden, evening
Do not send out fluorescent.When being scooped up with water ladle, shrimp seedling rapid can be gone and transfixion during against wooden dipper to wooden dipper in trip：Wooden dipper is stirred with finger pitch of the laps
Water, shrimp seedling can move about against the current.Observation two antennas of shrimp seedling can close up, or separately once amalgamator is good again once in a while, if two antennas
Often separate, or even can not close up, then shrimp seedling health status is poor.
5th, Feeding time and feeding volume
Prawn culturing early stage is fed 2 times daily, i.e., when 8,20 when feed；Cultivation mid-term is fed 3 times daily, i.e., when 8,19
When, 23 when feed；Cultivation the later stage feed 4 times daily, i.e., when 7,12 when, 19 when, 0 when feed.Early stage day feeding volume is shrimp gross weight
8.1%, mid-term is 6.8%, and the later stage is 4%-5%.Uniformly splashed at the side of a pond when feeding, night feeding volume, which is accounted for, feeds total amount day
50%
6th, water quality adjustment
The water colour in Penaeus Vannmei pond is preferably yellowish-brown.Early stage is cultivated, transparency is controlled in 30 cms, later stage
40 cms.Fermentation muck is imposed during cultivation weekly 1 time, every mu of consumption is 25 kilograms.
7th, disease control
Penaeus Vannmei is once fall ill, it is difficult to cure, should be to put prevention first.Prevention method：Disappear using C5H6Br2N2O2 is compound
Toxic agent, was used 1 time per 10-15 days, and per cubic meter of water consumption is 0.1 gram, and the molten full pond of water is uniformly splashed.Treatment method, is used
C5H6Br2N2O2 composite disinfectant 1 time, per cubic meter of water consumption is 0.2 gram, if being in a bad way, is changed every 2 days after the water of part, then make
With 1 time, per cubic meter of water consumption is 0.1 gram.Culture of Penaeus vannamei 65-80 days, specification reaches 60-70 grams, just can list out
Sell.Lobster basket netting gear harvesting can be used, the pool can be also done and arrest.
The present invention beneficial features be：Fertility is strong, and growth is fast, high efficiency.
Embodiment：
Embodiment：A kind of freshwater aquiculture technology of prawn, the prawn culturing early stage is fed 2 times daily, i.e., when 8,20 when
Feed；Cultivation mid-term feed daily 3 times, i.e., when 8,19 when, 23 when feed；Cultivation the later stage feed 4 times daily, i.e., when 7,12 when,
When 19,0 when feed.Early stage day feeding volume is the 8.1% of shrimp gross weight, and mid-term is 6.8%, and the later stage is 4%-5%.On the pool when feeding
Side is uniformly splashed, and night feeding volume, which is accounted for, feeds the 50% of total amount day.
