Abstract
A method for breeding freshwater shrimps in three seasons comprises the following steps of (1) pond conditions, (2) pond cleaning and sterilization, (3) shrimp seedling stocking, (4) bait casting management and (5) adult shrimp catching. The method is used for breeding the freshwater shrimps in three seasons , and the stocking density in autumn is reduced from conventional 9-10 ten thousands/mu to 5-7 ten thousands/mu. By means of a bait casting method adopting biological feeds and soybean meal, the casting and feeding times are increased from 1 to 3, the water level in a pond descends for 10 centimeters, the freshwater shrimp yield per mu reaches to 250-300 jin, the freshwater shrimps can appear on the market and be sold all the year round, and concentrated appearance on the market before wintering is effectively avoided.
Description
Technical field
The present invention relates to aquaculture field, especially cultivate the method for freshwater shrimp about three seasons.
Background technology
Freshwater shrimp is a kind of aquatic products of delicious food, and except delicious flavour, fine and tender taste advantage, its nutrition is also very abundant.The cultivation of freshwater shrimp was generally for two seasons: 12-1 month freshwater shrimp is put in a suitable place to breed, specification 400-500/mu, mu stocking rate 15-20 pound/acre, through growth in 4-5 month, to 5-6 month harvesting, breed shrimp seedling mid-June-mid-July, put seedling cultivation late July-mid-August, normally put 8-9 ten thousand/mu in a suitable place to breed, start to fish for listing December, 1 year cultivation spring and autumn 150-200 mu of regrowth hair freshwater shrimp per mu yields.Pond cultivating cultivation is unfavorable for four seasons listing all the year round, easily causes the price harmful competition of concentrating listing.
Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of method of three seasons cultivation freshwater shrimp, that three shrimp seedlings of annual input are put in a suitable place to breed, breeding density was reduced to and was put in a suitable place to breed 6-7 ten thousand tail/mus by conventional 9-10 ten thousand tail/mu autumn, adopt biological feedstuff to add the bait-throwing method of analysis for soybean powder, the number of times of throwing something and feeding is brought up to 3 times by 1 time, and pool inner water position declines 10 centimeters, make freshwater shrimp four seasons listing all the year round, quantity and quality is greatly enhanced.
Technical scheme of the present invention is achieved in the following ways: a kind of method of three seasons cultivation freshwater shrimps, comprises the following steps: 1) pond condition, 2) the medicine pool, 3 of cleaning up the pond) shrimp seedling puts in a suitable place to breed, 4) bait throwing in management, 5), become shrimp to fish for; It is characterized in that:
1), pond condition: select water source abundant, water quality is good, enters the construction pond, place in the convenient and pollution-free source of draining, intensive culture pool area 2-15 mu, depth of water 1-1.5 rice, smooth at the bottom of pond, mud 10-15 centimetre is advisable and is best with loam, sand takes second place; Slope, pond, than 1:3, has larger shoal to ingest for shrimp; In pond, transplanting water plants has waterweed, hydrilla verticillata etc. to account for water surface for aquaculture 20-30% to be advisable, and puts plantation before seedling;
2), the medicine pool of cleaning up the pond:
(1) one batch of cultivation in spring is arranged in and carries out the 12-1 month; Regrowth hair cultivation in summer is arranged in early July by the end of June and carries out; Three batches of cultivation were arranged in by the end of August and before carried out autumn; Method is first to drain Chi Shui, removes too much mud, finishing Chi Geng;
(2) quicklime, tea seed cake, crotons are selected in the medicine pool, and especially tea seed cake substitutes forbidden drug penta sodium pentachlorophenate, if spiral shell is more, also can use " spiral shell is killed ", " niclosamidum " to kill simultaneously;
3), shrimp seedling is put in a suitable place to breed:
(1) time: behind the medicine pool, 7 days property of medicine disappears, note 30 centimetres, new water with the close net filtration of 60-70 order, train water quality in water inlet in latter 7 days, every mu is watered bold and vigorous watering with urea 5-10 kilogram, puts seedling after water quality is grown fat again, and must first try water before putting seedling;
(2) specification quantity: spring: mu is put the juvenile prawn 10-15 jin of 300-500 tail per jin, started to fish for cultivation April and did pond results at the beginning of 6 month; Summer: it is shrimp seedling 5-6 ten thousand tails of 1.2-1.5 centimetre that mu is put specification, autumn mu to put specification be shrimp seedling 6-7 ten thousand tails of 1.2-1.5 centimetre, clean up the pond to mid-February next year.
(3) the lower pool: under juvenile prawn when the pool in the pool water temperature than working as ground temperature mean height 2-3 DEG C; Pool inner water position, than 10 centimeters of conventional declines, is 0.6-0.7 rice;
4), bait throwing in management:
(1) bait kind: add analysis for soybean powder with biological feedstuff, wherein: 40% bean powder, 30% photosynthetic bacteria powder and 30% chlorella;
(2) bait throwing in time and quantity: in the time that water temperature reaches more than 12 DEG C, start bait throwing in, water temperature 22-28 DEG C of bait throwing in a large number, daily ration, feeding quantity is controlled at the 3-15% of shrimp body gross weight; Throw something and feed 2-3 general every day, and when 8-9, account for total amount 1/3rd morning, and afternoon is when 5-6, and can throw 1 time when 9-10 the evening of the animated period of ingesting again, and accounts for altogether 2/3rds;
5), become shrimp to fish for: generally put in a suitable place to breed the 1-2 month in spring, late April starts harvesting, and early July puts in a suitable place to breed by the end of June, before fishes for by the end of August, and put in a suitable place to breed mid-August late July in autumn, starts harvesting December.
The present invention, three seasons of freshwater shrimp are thrown seedling cultivation, autumn, breeding density was by conventional 9-10 ten thousand tail/mus, reduce to and put 5-7 ten thousand tail/mus in a suitable place to breed, adopt biological feedstuff to add the bait-throwing method of analysis for soybean powder, the number of times of throwing something and feeding is brought up to 3 times by 1 time, pool inner water position declines 10 centimeters, make the per mu yield of freshwater shrimp reach 250-300 jin, the four seasons all can list marketing, has effectively avoided the price harmful competition of concentrating listing to cause before surviving the winter.
