Abstract
The invention discloses a procambarus clarkia autumn seedling reproduction method, and belongs to the technical field of aquaculture. The method comprises the following steps: (1) constructing a pond: arranging escape prevention walls around the pond; (2) desilting and insolating the pond, and disinfecting with calcined lime; (3) planting aquatic plants; (4) aquaculturing parent procambarus clarkia seedlings; (5) keeping the pH value of pond water at 7.5 to 8.5 to enable the dissolved oxygen content in the pond to be not less than 5 mg/L, controlling the transparency at 30 to 40 cm, spraying calcined lime dissolved water to the whole pond every 15 to 20 days, and spraying a microorganism preparation to the whole pond after 3 days; (6) reasonably controlling a water level; (7) catching the procambarus clarkia seedlings. The procambarus clarkia autumn seedling reproduction method fully considers the temperature condition and the growth characteristics and the aquaculture characteristics of procambarus clarkia, and the adopted aquaculture mode and the technology design are reasonable; anti-season aquaculture is realized, so that commercial shrimps can be sold in the market in advance, and considerable economic benefits are brought to farmers; the high occurrence period of diseases is avoided; the morbidity of the procambarus clarkia is reduced, so that the aquaculture risk of the farmers is reduced.
Description
Technical field
The invention belongs to technical field of aquaculture is and in particular to a kind of mating system of procambarus clarkii shrimp seedling.
Background technology
Procambarus clarkii, also known as Procambarus clarkii, are to be distributed the widest, the most common crayfish of cultivation in the world.Should
Macrobrachium nipponensis delicious, unique flavor, nutritious, high protein, low fat, rich in calcium, phosphorus, ferrum etc.,
Become the ticbit on urban and rural residents' dining table, day by day favored by domestic and international market, be also China in recent years
One of main aquatic products of foreign exchange earning.The discovery that procambarus clarkii is worth, lures that people fish in a large number into, causes
Wild procambarus clarkii resource is day by day exhausted.Increasing raiser starts artificial cultivation procambarus clarkii now.
The seedling supply of Procambarus clarkii cultivation at home is mainly dependence natural propagation at present, and idiophase is mainly annual
3～May of spring.After March, when heavy rain or water, embrace young shrimp and appear, finding has water
Ditch, river.The change embracing young shrimp in different quantity of different time of appearing with this period of 3～May
Change, build and define the pulse market of the commercial sized prawn source of goods later and its price change.In conjunction with for many years
Experience, annual 3～early June, Procambarus clarkii price highest, per jin reach 28～55 yuan, this is because this
Armful young phase of section period exactly Procambarus clarkii or spring Seedling then are not also brought up, and marketing shrimp amount is little, and
And the old shrimp mostly surviving the winter of market circulation, quality is bad, even March appear very early embrace son
The young shrimp seedling of shrimp, grows to the front standard being also not reaching to prawn at the beginning of 6 months.When the spring, Seedling brought listing up,
Also exactly nature and each raiser concentrate the period listing, and the market price goes way down, and price is very low.And
And the sickness rate highest of this various disease of period Procambarus clarkii, particularly it is susceptible to white spot syndrome, increase
The risk of cultivation.
Content of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of procambarus clarkii autumn Seedling mating system, real
Show anti-season cultivation, so that commercial sized prawn is listed in advance, bring considerable economic benefit to raiser.
A kind of present invention the technical scheme is that procambarus clarkii autumn Seedling mating system for achieving the above object,
It is characterized in that: mainly comprise the steps that
(1) pond setting: pond is deeply 150～200cm, pool wall slope ratio for 1:2～1:3, in the setting of pond surrounding
Anti-escape wall；
(2) clean up the pond sterilization:
Desilting is carried out to pond and is exposed to the sun, and with quick lime, pond is carried out disinfection；
(3) pasture and water cultivation:
Plant heavy water class and very water class water plant at pond bottom, water filling, the holding depth of water is 80～100cm, chases after
Apply compound fertilizer or bio-feritlizer；
(4) parent puts in a suitable place to breed:
In March, temperature is stablized when 10 DEG C～20 DEG C, every mu of procambarus clarkii Seedling putting 150～300 tails/kg in a suitable place to breed
Plant 3000～5000 tails, the female-male proportion of described seed is 2:1～3:1；
(5) feedstuff feeding:
March～early September feeds the mixture of plant feed and animal fodder, feeds 2 times daily；
Mid-September, little Qiu Seedling out started to feed mixed feed afterwards, fed daily 2 times, in described mixed feed
Protein content be 35%～41%；
(6) water quality management:
Keep water ph value 7.5～8.5, the dissolved oxygen content in pond is not less than 5mg/l；
Pond is carried out changing water, so that transparency is controlled in 30～40cm；
Every the molten water of every mu of use 4～6kg quick lime of 15～20d, carry out full pond clearance-type after molten water immediately and splash
Sterilization, is splashed full pond using microorganism formulation, and water transfer changes bottom；
(7) water table management:
March～May, water filling, water lev el control is in 60～80cm；
June～August, water filling, water lev el control is in 80～150cm；
September～November, water filling, water lev el control is in 150～200cm；
(8) fish for:
Mid or late October, when the specification of little Qiu Seedling reaches 300～500 tails/kg, fished in batches.
In described step (1), pond is provided with phytal zone and profundal zone.
In described step (1), anti-escape wall is plastic sheeting or mesh sheet.
When pond is carried out in described step (2) with dry pool sterilization, the consumption of every mu of quick lime is 90～110kg.
In described step (3), heavy water class water plant is algae dish and waterweed, and very water class plant is Caulis Zizaniae caduciflorae；Institute
Apply the fertilizer that compound fertilizer is containing n, p, k and trace element.
Procambarus clarkii parent seed in described step (4) is the strange land seedling taking at least more than two places.
Carry out multiple spot when feeding in described step (5) to feed；6:00～7:00 puts into the 30%～35% of day feeding volume,
17:00～18:00 puts into the 65%～70% of day feeding volume；The particle diameter of described mixed feed is 0.8～2.0mm.
Every 12～18d, water is once changed to pond in described step (6), quantity of exchanged water is whole pond water
10%～30%；Daily unlatching oxygen increasing equipment 1～6h, when dissolved oxygen in fish pond is less than 5mg/l, opens oxygen supplement
Equipment；Microorganism formulation is em bacterium or bacillus cereuss.
Described step (3) or step (7) pond in water filling, using 60～80 mesh sieve thin,tough silk filtered water inlets.
In described step (6), pond is when changing water, using 60～80 mesh silk cover filterings.
The technique scheme of the present invention compared with prior art has the advantage that the autumn of (1) crayfish
Ji Yumiao, makes commercial sized prawn carry first trimester mass marketed, realizes anti-season cultivation, fills up domestic artificial breeding
The blank of crayfish autumn shrimp seedling；(2) commercial sized prawn carries first trimester mass marketed, and price is usual 2～4
Times, improve the economic well-being of workers and staff of raiser；(3) cultivate procambarus clarkii autumn Seedling, avoid disease occurred frequently when
Phase, reduce the sickness rate of procambarus clarkii, thus reducing the cultivation risk of raiser.
