Description
Technical field
The present invention relates to field of marine product cultivation technology, and in particular to overwintering cultivation method outside sea shrimp room.
Background technology
In recent years, China's sea shrimp cultivation fast development, had become an important sea-farming cause.But cultivation
Close shrimp used still relies on sea and catches natural close shrimp.Due to the change of sea situation, the increase of marine fishing intensity and other factorses, affect
The quantity of spawning colony.Therefore, natural sea shrimp resource is increasingly reduced, and fishery output significantly declines.For conservation of nature money
Source, while ensureing the required parent stock that accrues, meets the sufficient amount of close shrimp of cultivation needs, is done step-by-step complete artificial
Cultivation, carries out close shrimp artificial overwintering work imperative.
The content of the invention
The purpose of the present invention is aiming at above-mentioned defect of the prior art, there is provided overwintering cultivation method outside sea shrimp room.
To achieve these goals, the technical scheme of present invention offer is：Overwintering cultivation method outside sea shrimp room, including it is following
Step：
1) survive the winter and prepare before pond：
Check wintering pond, preheating pond, storage cistern, water, draining, inflation, heating, the working order of power supply, wintering pond and pre-
Hot pond will be cleaned, and the bleaching fluid sterilization of the liquor potassic permanganate with 20ppm or 500-1000ppm, then with precipitation, mistake
Seawater flushing after filter, or it is clean with fresh water flush, discharging water to 1 meter, shrimp is put in wait；
2) sea shrimp parent shrimp enters pond：
Selected sea shrimp parent shrimp enters behind pond, adds the formalin of 20-25ppm, continuous charge to change water 1/5 daily in pond,
Formalin is removed after 5-7 days, can enter normal overwinter management, and close shrimp breeding density is 10-15 tails/m2；
3) water temperature regulation and control：
Sea shrimp parent shrimp enter overwintering culture pond after, can decline with natural temperature, less than 8 DEG C after, need heat, make to survive the winter
The temperature of phase is maintained at 15 DEG C, and Wintering Period water temperature keeps stable；After female shrimp mating, with spermatophore, when close shrimp moves pond or changes water,
The difference of two water temperature, must not exceed 0.5 DEG C；The method of regulating and controlling temperature, by increase and change preheating water or into pond directly
Heating, keeps room temperature to be higher than 2-3 DEG C of water, prevents pool inner water temperature to scatter and disappear；Sea shrimp parent shrimp enters the lifting in pond initial stage and the later stage of surviving the winter
Water temperature, after face and often 1 DEG C of lifting, all should should stablize temperature adjustment again in 2-3 days by daily less than 1 DEG C of temperature difference lifting, make close shrimp day by day
Adapt to；
4) bait throwing in：
The bait of Wintering Period includes scallop class, cuttlefish, clam worm, small shrimpses and fish, and shrimp of getting married need to be processed during bait throwing in can be with
The fritter ingested, when feeding small fishes, will avoid the kind for using fat content higher, can the alternately throwing of various bait when having ready conditions
Hello, it is to avoid the single bait of Long-Time Service；Daily ration, feeding quantity is the 3-5% of sea shrimp parent's shrimp body weight, is fed daily 2 times, and feed in the morning always needs
The 1/3 of amount, feeds remaining 2/3 afternoon；
5) intensity of illumination is controlled：
Control intensity of illumination, using shading device, in the whole normally overwintering culture stage, intensity control within 500 Le,
When night closes electric light, light intensity should be made gradually to weaken；
6) inflate：
In order to keep wintering pond water quality to be adapted to the needs of parent shrimp, entering the pond initial stage in close shrimp should inflate in right amount, it is desirable to daily molten
Solution oxygen is not less than 5mg/L, and bubble is little, and surviving the winter, the later stage carries out continuous charge；
7) draining and blowdown：
Daily soil pick-up changes water once, and changing before water should stop inflation, first excludes remaining water, and daily quantity of exchanged water is 1/5-1/3, row
Residual bait and other dirts are removed after water, dead shrimp, debris are fished for；After draining and sink bottom, should add in time through fully precipitation,
The new water in the preheating pond of temperature is filtered, has mixed up, the water temperature preheated in water temperature and wintering pond in pond is consistent；
8) water standard of overwintering culture phase：
Water temperature：15℃；Salinity：15-35 ‰, appropriate 25-35 ‰；PH value：7.6-8.6；Ammonia nitrogen：Below 0.5ppm；Dissolving
Oxygen：More than 5mg/l；Chemical oxygen consumption (COC)：Below 3mg/l；Water readability：1 meter of depth of water, close shrimp and bait it is high-visible.
Beneficial effects of the present invention are：Overwintering cultivation method outside the sea shrimp room that the present invention is provided, can be applied to sea shrimp parent
The overwintering culture of shrimp, implements to operate according to the inventive method, and, up to more than 70%, close shrimp spawning rate can for female parent shrimp overwintering survival rate
Up to more than 80%, every square metre of wintering pond can cultivate into female parent shrimp 7-10 tails of surviving the winter.
