Embodiment
The introduced parent shrimp of high-effective living-protective intensive culture technology for introduced parent shrimp of the present invention is: the close shrimp of buying outside state (border); or the close shrimp of buying from domestic each department; the close shrimp of no matter outside domestic or state (border), buying; variation has all taken place in its environmental factor; add turning from side to side of long-distance transport; if technical management is improper, often cause very big loss.Therefore, the technical measures of taking must adapt to its living environment, just can guarantee high survival rate.
High-effective living-protective intensive culture technology for introduced parent shrimp is step by the following method:
(1) cleanse and disinfect in cultivation pond and workshop
Parent shrimp rearing pond water is thoroughly cleaned up, cultivate pond environment on every side and also must clean up, foreign material around eliminating keep cultivating the neatly clean of workshop, pond, in case the mutual infection between the Chi Yuchi.
With strong chlorine oil 1000-1500ppm or formaldehyde 1000-1500ppm each is cultivated the sterilization of splashing of pond and whole workshop, or adopt two kinds of medicines successively to carry out disinfection, sealed door and window then 48 hours, allow whole cultivation pond and workshop enclosing sterilizing, can effectively kill various bacteriums and infectious disease, prevent that the disease after close shrimp is introduced from taking place.
(2) cultivate the pond water inlet
Cultivate the pond and behind enclosing sterilizing, just can intake, take out nature seawater and enter after through husky coarse filtration (or through sedimentation basin, storage cistern) and cultivate the pond, dark 50-60 centimetre of water inlet position; Draw up the seawater that comes and should reach following index: pH value 7.9-8.4, below the nitrite 0.10mg/L, below the ammonia nitrogen 0.40mg/L; If basic symbols is share the water requirement then can be adopted, if do not reach the water requirement then draw water in addition or carry out water treatment and use again.
(3) temperature adjustment, accent salt
Originally temperature, the salinity of life Chi Shui or transportation and packing water compared to being drawn into the water of cultivating the pond and close shrimp, adjust to roughly the same as far as possible, water temperature preferably is no more than ± and 2 ℃, salinity is no more than ± and 2 ‰, if the close shrimp of knocking down surpasses 5 ℃ of temperature, salinity 5 ‰ quickly, can influence survival rate, normally the pH value of nature seawater generally need not adjusted, if abnormal nature seawater then should not adopt.
(4) adjust light intensity: the light intensity of parent shrimp rearing pond workshop condition is transferred to comparison half-light degree, and promptly light intensity is: between the 15-40IX, similar with the light intensity of original close shrimp living environment.
Its reason is: originally close shrimp lives in the bigger deep pond, the water in pond is relatively more fertile, algae and various material are many, the intensity that solar irradiation is mapped in the pond is more weak, prawn adapts to this environment for a long time, if have only in the strong cultivation pond of 50-60 centimetre and light to the depth of water quickly, just cause prawn urgent to living environment easily, be easy to cause immunity degradation and fall ill.If the light intensity of cultivating the pond is transferred to similar with former shrimp pond, just can makes prawn as living in original environment.
(5) sterilization of cultivation Chi Shui and close shrimp;
Its effect of dispensing sterilization has two: one, to being about to enter the pond water sterilization of close shrimp.The 2nd, to the sterilization of the close shrimp health of coming in, can prevent and control prawn disease and take place.The kind and the method for throwing in medicine are: close shrimp advance the pond before 30 minutes every cubic metre of water body throw penicillin 100--130 ten thousand units and streptomycin sulphate 100--130 ten thousand units, the parent shrimp went into the pond 48 hours, throw methylene blue 0.025-0.03ppm after the blowdown again, carry out disinfection again and nurse one's health water colour.
(6) close shrimp goes into the pond: after all work were ready, promptly affable shrimp went into the pond.The parent should move fast when shrimp goes into the pond, carefulness again, gently removes and puts down gently, prevents to damage the shrimp body.If the packed close shrimp of import, then should be former bag put in the pond 15-20 minute into, allow its about temperature unanimity release again, when emitting the pond, also should open the advanced a part of water of sack, advance a part of water again, advance a part of water (continuing 1-2 minute) again, to adapt to the stress reaction that every reasons such as salinity have big difference.Or open one bag, and detect its temperature, salinity, put the pond again into after every index of good Chi Shui to be adjusted.The parent shrimp enters to be cultivated after the pond, keep the comparison quiet environment, and too many artificial disturbance factor is not arranged, and close shrimp is in keeps regulating aeration quantity simultaneously in the static environment.
(7) management:
1. feed intake and want science, accurate, will throw agreeable to the taste, high-quality feed after close shrimp comes in.If the close shrimp that comes in from the shrimp pool, can throw particle shrimp material a bit of fine quality earlier, described feed of fine quality is meant the manufacturer that credit is good, stay in grade, the degree of fixation height, soaked 2 hours are not loose, have a fish like smell no musty, the people edible it, have sweet felling, feed coefficient (FCR) is between 0.8-1.1, and inventory is to eat up with 1 hour to be as the criterion.Throw material such as a little fresh and alive insects again, to strengthen the physique of newly advancing close shrimp, the variation that shakes down.General after 7-14 days stationary phase, feeding intake by the mode of usual parent shrimp rearing gets final product.
2. the adjustment of light intensity: be transferred to when close shrimp has just gone into the pond than half-light degree (15-40IX), the 6-7 days follow-up cumulative light intensities that add recover ordinary ray intensity after 10 days, coincide with the light of cultivating algae like this.
3. cultivate the algae phase, conditioned water quality water colour: change water 30-50 centimetre every day, adopt natural sea-water to get final product, keep in the water a certain amount of algae kind being arranged, so that in the cultivation pond, breed through husky coarse filtration.If overgrow with algae around the cultivation pond, and threw in the various profitable strains of 1ppm every 1-2 days, pond water will be very stable like this, and close shrimp is susceptible disease not, and physique can be healthy and strong, the bosom ovum soon and many, the output height.
