Description

The method that a kind of river snail is cultured

Technical field

The present invention relates to the method that a kind of river snail is cultured.

Background technology

The river snail meat is tender and crisp, and delicious flavour is nutritious, and the function of nourishing and fit keeping function is arranged, and is the aquatic products that China both urban and rural residents likes.River snail in the streamside, all there is distribution in pond, irrigation canals and ditches, paddy field etc., have that fertility is strong, fast growth, output height, be easy to advantage such as feeding and management.Support spiral shell in recent years and become the new social connections that the man people in many areas build up the family fortunes already.According to investigations, propagate river snail artificially and can gather in the crops 1800～2000 kilograms, 3500～4000 yuan of the output values for general every mu.

Summary of the invention

The present invention relates to the method that a kind of river snail is cultured, implement by following four aspects: (1) cultures the place: all have smooth irrigation canals and ditches, paddy field moorland, the field of lying fallow, vegetable garden ditch, orchard ditch, flow slowly small stream beach, the fish pond, pond etc. in running water source all can put in a suitable place to breed.Propagate artificially should select to have abundant water resources, the place of the fresh cleaning of water quality builds ground.(2) plant the spiral shell source: selecting body weight is 15～20 grams, and color and luster light brown, shell is thin, body is round, tail is blunt fresh and alive female spiral shell are as kind of a spiral shell.Breed commodity spiral shell can be selected female spiral shell and directly put in a suitable place to breed, if culture kind of spiral shell for breeding usefulness, then should arrange in pairs or groups in 2: 1 ratio of male and female and put in a suitable place to breed.(3) planting spiral shell throws in: culture the commodity spiral shell and drop into 10 female spiral shells of laying eggs and get final product for general every square metre, if immature little young spiral shell should be pressed the male and female ratio input of 1: 1 or 2: 1.If special breeding seedling, can throw in 100～150 on the female spiral shell of laying eggs for every square metre, immature young spiral shell, female-male proportion were then thrown in by 2: 1 or 3: 1.(4) feeding and management: planting Luo Chi should clear up earlier and sterilize, and spreads the fertile mud of 20 cm thicks at the bottom of the pond.Inject fresh water then, the water quality of fostering and apply fertilizer.Day feeding volume be breechblock heavy 1%～3%, o'clock feed 1 time every morning 8～9.Refresh the water periodically, keep water cleaning.Need often inject new water, and add profundal zone when surpassing 30 ℃ when water temperature summer, so that reduce water temperature; Can adopt winter mend night, white row's pipe water way, regulate water layer, also can execute barnyard manure such as a little pig manures, cow dung, can temperature raising, the water quality of fostering and apply fertilizer again.

Specific implementation method

1. it is strong to culture place river snail vitality, and disease is few, not tight to culturing site requirements, and all have smooth irrigation canals and ditches, paddy field moorland, the field of lying fallow, vegetable garden ditch, orchard ditch, flow slowly small stream beach, the fish pond, pond etc. in running water source all can put in a suitable place to breed.Propagate artificially should select to have abundant water resources, the place of the fresh cleaning of water quality builds ground.Cement pit also can be built in the pond of can cutting the earth.Area is decided according to the breed scale.Commodity spiral shell pool area is advisable with about 100 square metres, and breeding spand generally with 40 square metres better.Dark general 70～80 centimetres of pond, 40～50 centimetres of the depth of waters.20 centimetres of fertile earth of living of place mat at the bottom of the pond, the two ends in pond are established water inlet and delivery port respectively, prevent escaping with wire netting or plastic wire.

2. planting spiral shell source annual 6～September is a large amount of egg reproduction phases of river snail.Distribution ground such as seedling can be from the pond, irrigation canals and ditches, paddy field are manually picked up, and also can arrive market and buy commodity and become spiral shell, and therefrom selecting body weight is 15～20 grams, and color and luster light brown, shell approaches, body is round, tail is blunt fresh and alive female spiral shell are as kind of a spiral shell.Female spiral shell individuality is bigger, and the spiral shell body is round slightly partially, and face-piece is recessed flat; Male spiral shell individuality is less, and the spiral shell body is longer, the face-piece projection.Breed commodity spiral shell can be selected female spiral shell and directly put in a suitable place to breed, if culture kind of spiral shell for breeding usefulness, then should arrange in pairs or groups in 2: 1 ratio of male and female and put in a suitable place to breed.

3. plant the happiness of spiral shell input river snail and perch in shallow waters such as pond, irrigation canals and ditches, paddy field, be good at sludge.It is vigorous to ingest during 20～25 ℃ of water temperatures, and it is the fastest to grow; Water temperature is lower than 15 ℃ or be higher than 30 ℃ and stop to ingest; It is cruel that water temperature is reduced to the winter of burying below 10 ℃, and water temperature was raised to and just recovered more than 15 ℃ to look for food next year.Most of provinces and regions of China 3～11 are monthly throws in breed.Kind of spiral shell is put in a suitable place to breed in the natural region, cultures the commodity spiral shell and drops into 10 female spiral shells of laying eggs and get final product for general every square metre, if immature little young spiral shell should be pressed the male and female ratio input of 1: 1 or 2: 1.Children's spiral shell grows up to big spiral shell, and mate and oviposit hatches little river snail again, just they can be formed the commodity spiral shell.If special breeding seedling, can throw in 100～150 on the female spiral shell of laying eggs, immature young spiral shell for every square metre, female-male proportion was then thrown in by 2: 1 or 3: 1, and general 4 ages, above close spiral shell can produce 40～50 young spiral shells, and 2～3 week of postpartum, the son weighed 0.025 gram, begin to ingest, raise and to raise up seed again after 1 year.

4. feeding and management kind Luo Chi should clear up earlier and sterilize, and spreads the fertile mud of 20 cm thicks at the bottom of the pond.Inject fresh water then, the water quality of fostering and apply fertilizer.The water surface can be put water lettuce, red green apple etc. in a suitable place to breed, get food so that plant spiral shell, but also winter protection is avoided heat.Plug small bamboo or little batten in the pond, the confession river snail perches and lays eggs.The river snail feeding habits are assorted, and the small animal in the water and plant and algae etc. all are natural baits.Children's spiral shell also to add after growing up feed rice bran, wheat bran, bean dregs, Ipomoea batatas, insect, fish frightens and pluck, offcuts etc., with good conditionsily also can feed manufactured feed.Day feeding volume be breechblock heavy 1%～3%, o'clock feed 1 time every morning 8～9.After should chopping up, roughage just throws in.The pond many with water plants raised together with in fertile paddy field and fish spiral shell, can throw or not throw feed less.Refresh the water periodically, keep water cleaning.Need often inject new water, and add profundal zone when surpassing 30 ℃ when water temperature summer, so that reduce water temperature; Can adopt winter mend night, white row's pipe water way, regulate water layer, also can execute barnyard manure such as a little pig manures, cow dung, can temperature raising, the water quality of fostering and apply fertilizer again.

Points for attention:

1. river snail is very sensitive to agricultural chemicals, weed killer herbicide, petroleum-type and industrial sewage, should carry out the work of forfending.Chloride running water also should not be used for culturing.

2. river snail is an ovoviviparous animal, and annual early June, mid-August, early September are the peak periods that breeding is laid eggs, and will fish for into spiral shell selectively during results, stay female spiral shell more, in order to breeding, increases output.Preferably avoiding breeding the peak period receives and drags for.
