Abstract
The invention discloses a method for breeding freshwater shrimp parents by utilizing a river crab culture pond, which comprises the following steps of a, carrying out preparation before breeding; b, breeding seedlings; c, feeding; d, fishing the parents and separating the parents in different ponds. According to the invention, the freshwater shrimp parents are bred by utilizing superior ecological conditions and sufficient bait resources of the river crab culture pond; the patents bred by the method is higher than parents bred in a special pond in both the aspects of specification and yield; the specification and the quantity of carrying eggs of ovigerous females bred by the method are obviously higher than those of ovigerous females bred in the special pond; culture of river crabs is not influenced; freshwater shrimps mainly eat residual feeds of the river crabs and are properly additionally fed with soybean cakes and bran, so that pond port resources are saved and labor intensity is reduced.
Description
Technical field
The present invention relates to a kind of method of utilizing the culture of Chinese mitten crab pond to cultivate the freshwater shrimp parent, belong to shrimps aquatic biological breeding technical field in agriculture aquaculture.
Background technology
Freshwater shrimp parent's breeding method is all that cultivate in special pond at present.Introduce the freshwater shrimp parent in the 2～March in every year, put into special pond and start to carry out parent culture, cultivate to mid or late May, after a large amount of oogenesis of freshwater shrimp, shrimp with ovums proceeds to special pond and grows seedlings.The time that the button crab is put in the culture of Chinese mitten crab pond in a suitable place to breed is before and after March, if the freshwater shrimp parent carries out the cultivation of special pond, this pool mouth just can not be used for carrying out culture of Chinese mitten crab, and pool resources can not be utilized effectively.Culture of Chinese mitten crab pond ecological environment is superior, feed abundance, the growth of most suitable freshwater shrimp.Freshwater shrimp can utilize the residual bait of river crab, and freshwater shrimp does not possess aggressiveness simultaneously, on the not impact of cultivation of river crab.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is to, a kind of method of utilizing the culture of Chinese mitten crab pond to cultivate the freshwater shrimp parent is provided, improved specification and output, saved pool mouth resource, reduced labour intensity.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of method of utilizing the culture of Chinese mitten crab pond to cultivate the freshwater shrimp parent, it is characterized in that, and comprise the following steps:
A. put front preparation in a suitable place to breed
1. reinforce pool bank and the anti-facility of escaping;
2. the sterilization of cleaning up the pond: Winter Dry is removed mud behind the pool, thoroughly tans by the sun at the bottom of the pool 1 month, puts first 20 days water inlet 10～30cm in a suitable place to breed, and after every mu of use 50～100kg quicklime water, evenly splash in full pond;
3. rich water: put in a suitable place to breed and be filled to 50cm the last week, every mu of use is through the fertilizer 100～200kg of fermentation;
4. plant pasture and water: plantation waterweed and hydrilla verticillata; B. seed is put in a suitable place to breed
Shrimp species are put in a suitable place to breed: freshwater shrimp 10～15kg that every mu of stocking size is 800～1000 tails/kg in 2～March, and female-male proportion is 3～5:1;
The crab kind is put in a suitable place to breed: 600～800 of button crabs that every mu of stocking size is 100～120/kg in March;
C. feedstuff feeding
After river crab is put in a suitable place to breed, every mu of disposable input 300～500kg spiral shell; Spring, water temperature reached 15 ℃ of river crab pellets that start to throw something and feed, day in 3～April feeding volume be 1～3% of river crab body weight, day in May feeding volume be 3～8% of river crab body weight; Freshwater shrimp take eat river crab residual bait as main, eat when heavy, auxiliary throw something and feed soya-bean cake and wheat bran, throw something and feed weekly once, feeding volume is 3% of freshwater shrimp body weight;
D. the parent fishes for a minute pool
Mid-May, the cage fishing freshwater shrimps checks the oogenesis situation weekly, and when 90% female shrimp starts oogenesis, cage is fished for shrimp with ovums and carried out special pond and grow seedlings.
Further technical scheme is:
Above-mentioned steps 4. in, waterweed is planted before the crab kind is put in a suitable place to breed, hydrilla verticillata is planted before clear and bright, two kinds of algae cultivated areas account for 30% of water area.
In above-mentioned steps c, while throwing something and feeding the river crab pellet, minute morning and dusk secondary are thrown something and fed, and the morning 7～8 feeding volume accounts for 1/3 of day feeding volume, and 17～18 feeding volumes account for 2/3 of day feeding volume at dusk.
In above-mentioned steps c, after March 20, river crab is every other day supplemented the small fish of throwing something and feeding, the crab of at every turn throwing something and feeding heavy 3%.
After feedstuff feeding, also comprise water level management: water level is controlled at 0.5～0.6m, meets continuously overcast and rainy or significantly before the cooling arriving, adds water to 0.8 m.
After feedstuff feeding, also comprise regulating and controlling water quality: in April, every 15 days, according to the water quality condition regulating water quality, make the pond waters pH value remain on 7.5～8.5, water transparency remains on 30～40cm; Regulate dissolved oxygen in water, more than the maintenance dissolved oxygen reaches 5mg/L simultaneously.
At the beginning of 4 months～and using the microorganism formulation regulating water quality at the beginning of 5 months, described microorganism formulation is one or more in bacillus, nitrifying bacteria, late May is used the photosynthetic bacteria regulating water quality.
Use the micro-pore oxygenation facility to regulate dissolved oxygen in water.
Regulating and controlling water quality also comprises: changed water according to the gentle tender feeling condition of pond water quality, the 1/4-1/5 that each quantity of exchanged water is Chi Shui, change one time water in every 10 days.
Also comprise daily management: sooner or later respectively patrol the pool once, remove in time floating careless residual bait, prevent water quality deterioration.
The invention has the beneficial effects as follows: utilize the superior ecological condition in river crab pond and sufficient food resource to cultivate close shrimp parent, the parent of its cultivation all cultivates the parent higher than special pond on specification, output, the specification of shrimp with ovums and oogenesis amount also are significantly higher than the shrimp with ovums that cultivate in special pond, and do not affect the cultivation of river crab; Freshwater shrimp be take and ingests the residual bait of river crab as main, suitably increases throwing something and feeding of soya-bean cake, wheat bran, has saved pool mouth resource, has reduced labour intensity.
Embodiment
For further disclosing technical scheme of the present invention, below in conjunction with specific embodiment, describe embodiments of the present invention in detail: a kind of method of utilizing the culture of Chinese mitten crab pond to cultivate the freshwater shrimp parent comprises the following steps:
