Technical field
The present invention relates to aquaculture technology, relate to a kind of technology that adopts the two-period form controlled ecological fresh waterization efficiently to culture Penaeus Vannmei specifically.
Technical background
Because aquatic products have characteristics such as delicious flavour, nutritious, strong health-care function, be found in recent years and be rich in, and more and more be subjected to people's welcome the medicable n of cardiovascular disease~3 unsaturated fatty acids and other active substances.The nutritive value of aquatic products and peculiar flavour are understood, are admitted and favor by the consumer gradually, this progressively enlarges its market colony, especially in recent years be subjected to the influence of rabid ox disease and bird flu in the world, the consumer produces the feared state of mind to animal products, sight is turned to aquatic products, demand to aquatic products significantly increases, and in rising trend always, and the consumption market reaches its maturity.The main consumer nation of aquatic products demands such as U.S., Japan and Korea S. heighten, and calendar year 2001 U.S.'s import aquatic products reach 1,900,000 tons, record high.Penaeus Vannmei is with its delicious meat in recent years, and mouthfeel well has prawn series products import requirements such as very big consumption market, particularly fast food restaurant very big abroad.China's shrimps goods total export value broke through 1,000,000,000 dollars in 2003, was the highest product of product water outlet value.Culture Penaeus Vannmei and have vast market prospect.
Penaeus Vannmei (Penaeus vannamei Boone, 1931), be under the jurisdiction of Arthropoda (Arthropda) Crustachia (Crustacea) Decapoda (Decapoda) swimming suborder (Natantia) Penaeidae (Penaeus) Litopenaeus subgenus on the taxonomy.The Penaeus Vannmei crust is thinner, and whole body is transparent, and the tail fan outer rim is banded red, and two long men are pink, and carapace is short, and the frontal eminence upper limb has 8~9 teeth, and lower edge is 2 teeth, becomes the long maximum of shrimp body to reach 23 centimetres in a left side.Originate in the pacific warm water of South America waters, Peru the north to the Gulf of Mexico bank that mainly distributes is the highest shrimp species of single rate in the present three big cultured prawns in the world.It has advantages such as vitality is strong, wide adaptability, and premunition is strong, growth is rapid, low to the forage protein content requirement, dressing percentage is high, the dried up time-to-live is long, is the improved seeds of intensification high yielding culture.
The aquaculture organism of Penaeus Vannmei is learned characteristics: the breeding cycle is long, can the anniversary carry out seed production; Nutritional requirement is low, and Protein content accounted for 20%~25% o'clock in the bait, can satisfy its normal growth demand, and the ratio of protein content need account for 40%~45% in the Chinese prawn bait; Feed coefficient is generally about 1.4.Juvenile prawn shell in 4~6 days once, 15 gram above prawns about fortnight shells once, the beginning of each month one, 15 front and back prawns are understood a large amount of shells, growth rate is the fastest in 60 days, after this growth rate is obviously slowed down, its daytime, night all ingest; Strong, the wide adaptability of Penaeus Vannmei vitality, salinity accommodation 0~45 ‰, the suitableeest scope are 10~35 ‰, under the situation of desalination gradually, can be normal growth in 0.5 ‰~2 ‰ the fresh water in salinity also; Penaeus Vannmei is cultured 23~34 ℃ of suitable water temperatures, and the suitableeest growth water temperature is 28~32 ℃, stops to ingest below 19 ℃, begins to occur death below 9 ℃, and water temperature is bigger to its organism metabolism influence greater than 35 ℃.PH accommodation 7.6~8.6, dissolved oxygen threshold value are 1.2mg/L, water nutrition salt: phosphate 0.1~0.3mg/L, and silicate 2.0mg/L, ammoniacal nitrogen is less than 0.4mg/L; Below nitrite 0.05 mg/litre; Below hydrogen sulphide 0.1 mg/litre.Growth is rapid, high, the neat specification of output, and can carry out high-density breeding is the improved seeds of intensification high yielding culture; Adaptability and resistance against diseases are strong.Because white shrimp can be a normal growth in 0.5 ‰~2 ‰ the fresh water in salinity, therefore is fit to mariculture, also is fit to river mouth brackish water desalination cultivation.
The desalination cultivation Penaeus Vannmei has the incomparable superiority of mariculture really, cut off that pathogene the seawater infects and the Secondary cases virus disease that causes from the water source head, thereby greatly reduced M ﹠ M.Though Penaeus Vannmei can be grown in fresh water, growth rate is slow, yields poorly raiser's deficiency in economic performance.Simultaneously, because Penaeus Vannmei is cultured suitable water temperature at 23~34 ℃, the suitableeest growth water temperature is 28~32 ℃, stop to ingest below 19 ℃, begin to occur death below 9 ℃, water temperature is bigger to its organism metabolism influence greater than 35 ℃, therefore, suitable time weak point of growing with Penaeus Vannmei is unfavorable for the raising of output in the whole year.
Summary of the invention
Can in fresh water, grow for overcoming Penaeus Vannmei, but growth rate is slow, the problem that yields poorly, the present invention has set up the efficient cultural technique of Penaeus Vannmei two-period form controlled ecological fresh waterization, it is characterized in that: the phase I is with shrimp seedling 28-35 days juvenile prawns to long 3~6 centimetres of body of fresh water cultivation in the training seedling pond of controllable temperature; Second stage adopts controlled ecological fresh water breed Penaeus Vannmei technology, is about to juvenile prawn and removes to the brackish water Tu Chi of low salinity and support 100 days to becoming shrimp.Further improve Penaeus Vannmei cultured output and economic benefit.
