Abstract
The invention discloses a kind of method of artificial breeding river snail, it is characterised in that including following aspect：（1）Seedling selects, and selective body focuses on 18 23g, shell color and luster light brown, the river snail that shell is thin, body rounded tail is blunt and is used as kind of a spiral shell, immerses in saline solution and sodium chlorate solution clean respectively；（2）Domesticating and cultivating, is built in culturing chamber by river snail seedling immigration box for breeding and carries out domesticating and cultivating, feed nutrient fodder daily；（3）Branch mailbox cultivates, according to female, male river snail 89 in each box for breeding:46 proportioning mixed breedings, mixed breed poor 1 time of cooling in every 3 days after 12 months, add plant extraction liquid into box for breeding 1 time every 23 days of April and September, persistently carry out 1 month；（4）Young spiral shell cultivation：Young spiral shell is transferred to independent box for breeding and carries out constant temperature cultivation, is periodically carried out disinfection using liquor natrii hypochloritis to young spiral shell and box for breeding, cultivation moves to culturing chamber in 23 months and cultivated jointly.
Description
Technical field
The invention belongs to aquatic breeding field snail technical field, and in particular to a kind of method of artificial breeding river snail.
Background technology
River snail, belongs to fresh water mollusk, it is distributed widely in rivers, lake and pond, and common kind is with China
Based on circle river snail, it is stronger to water quality requirement, and the speed of growth is slow, and yield is relatively low.River snail habit likes that water quality is limpid, water plant is rich
Rich, miniflow water environment, using the polygamy such as water plant young stem and leaf, organic matter, phytoplankton, algae food as food；Its optimum is given birth to
Long temperature is 20-27 DEG C, when water temperature is less than 10 DEG C or higher than 30 DEG C river snails can stop entering rest period；River snail meat is fresh
It is beautiful, full of nutrition, wherein containing nutritional ingredients such as abundant protein, fat, mineral matters, to hot eyes, jaundice, tinea pedis, hemorrhoid
Deng having effects that, and river snail can also be used as medicine, and have effects that clearing away heat and promoting diuresis, removing dampness and detoxicating act on.The delicious mouthfeel of river snail and
Trophism, will be widely welcomed in the market, then market supply is mainly propagated artificially with collecting wild river snail, with need
The amount of asking increases, and collecting river snail with acquisition mode cannot meet to cultivate scale demand, there is provided a large amount of good young spiral shells of quality become
Raiser there is an urgent need to；Patented invention：201410083931.2 the cultural method of wild river snail provides a kind of young spiral shell breeding side
Method, in its scheme in addition to domesticating and cultivating, other methods are little with normal aquatic breeding field snail difference, and the young spiral shell of crop field breeding easily by
Parasite, pathogenic bacteria infringement, the speed of growth is slow, survival rate is low.
The content of the invention
The present invention is directed to the problem of existing：Then market supply is mainly propagated artificially with collecting wild river snail, with
Demand increases, and collecting river snail with acquisition mode cannot meet to cultivate scale demand, there is provided a large amount of good young spiral shells of quality into
For raiser there is an urgent need to；Patented invention：201410083931.2 the cultural method of wild river snail provides a kind of young spiral shell breeding
Method, in its scheme in addition to domesticating and cultivating, other methods are little with normal aquatic breeding field snail difference, and breeding young spiral shell in crop field is easy
Encroached on by parasite, pathogenic bacteria, the speed of growth is slow, survival rate is low.To solve the above problems, the present invention provides a kind of artificial breeding
Educate the method for river snail.
The present invention is achieved by the following technical solutions：
A kind of method of artificial breeding river snail, comprises the following steps：
（1）Seedling selects：Selective body focuses on 18-23g, shell color and luster light brown, the river snail that shell is thin, body rounded tail is blunt and is used as kind of a spiral shell, can
The river snail that life is vigorous, fertility is strong is selected, improves the quality for breeding young spiral shell, wherein female spiral shell is big and justifies, outside male spiral shell
Shape is small and sharp, and kind of spiral shell is immersed the saline solution that mass concentration is 0.5% soaks 7-9min, is then immersed in liquor natrii hypochloritis clear
3-4min is washed, morbidity rate and the death rate is reduced, obtains river snail seedling；
（2）Domesticating and cultivating：Into box for breeding plus clear water stand more than 6h, by river snail seedling immigration box for breeding be built in culturing chamber into
Row domesticating and cultivating, is improved to breeding environment adaptability, and cultivation on daytime temperature is 22-26 DEG C, and night cultivation temperature is 15-18
DEG C, nutrient fodder is fed according to the 1.5%-2% of river snail weight, there is provided the various nutritional ingredients needed for river snail, improve growth daily
Speed, feeds at twice, feeds interval time in more than 8h, and field must be tamed after 2 months by replacing once water in cultivation, cultivation weekly
Spiral shell；
（3）Branch mailbox cultivates：According to female, male river snail 8-9 in each box for breeding:4-6 is matched, and river snail quantity exists in each box for breeding
70-90, nutrition raising is fed according to rural area weight 1.8%-2.2%, feeds in three times daily, cultivates 21-24 DEG C of room temperature, daytime
3-5 DEG C of the night temperature difference, after mixed breed 1-2 months every 3 days cooling differences to 10-12 DEG C 1 time, adjusted by the temperature difference and promote river snail numerous
Grow, in addition plant extraction liquid 1 time into box for breeding per 2-3 days of April and September, its plant extract component contained can promote field
Spiral shell sexal maturity, improves the fertility of river snail, persistently carries out 1 month, river snail proceeds by breeding；
（4）Young spiral shell cultivation：Independent box for breeding is transferred to after young spiral shell is cultivated 10-15 days in former box for breeding to be cultivated, nutrition
Feedstuff feeding amount is the 0.4%-0.6% of young breechblock weight, and 1 water was replaced per 3-4 days, and uses within 4-6 days liquor natrii hypochloritis to children
Spiral shell and box for breeding carry out disinfection, and can improve young spiral shell survival rate and the speed of growth, cultivate 2-3 months and move at a temperature of 20-24 DEG C
Cultivated jointly to culturing chamber.
Step（1）The liquor natrii hypochloritis, its mass concentration are 30ppm.
Step（2）The nutrient fodder, it, which is respectively configured to sub-prime gauge part, includes：23-27 parts of fish meal, peanut meal 14-
17 parts, 10-13 parts of carapace powder, 7-10 parts of chlorella powder, 5-8 parts of albumen slag, 4-6 parts of mulberry leaf powder, 2-5 parts of fishbone dust, chelating calcium 1-3
