Description

A kind of efficient cultural method of spiral shell
Technical field
The present invention relates to technical field of shellfish culture, and in particular to a kind of efficient cultural method of spiral shell.
Background technique
Spiral shell is being commonly called as rectangular Bellamya sp, for the rectangular Bellamya sp of Viviparidae animal or other belong to the entirety of animal, spiral shell Shell cone, hard thick, shell is about 3 centimetres high, and shell is top, and 7 layers of gyration, suture is deep, and body whorl is bigger;Shell surface yellowish-brown is deep brown Color has apparent growth line and thicker spiral shell rib, and faucal oval, edge is complete, operculum cutin, yellowish-brown, oval, smoothly, On have the growth lines of concentric annular arrays, spiral shell often inhabits that cool in summer and warm in winter, subsoil is soft, bait lake abundant, pond, water In the river small stream of field and unhurried current, its most suitable growth water temperature is at 20~25 DEG C or so, when water temperature is up to 15 DEG C or less and 30 DEG C or more Stop feeding activity, artificial breeding river snail can dig pool specialized raising, natural rice field, marsh, irrigation canals and ditches can also be used, can also be same Fish mixed breeding, but requires breeding water body nontoxic, harmless, pollution-free, such as utilizes paddy field aquaculture, then can not applying pesticides, Bu Nengli Rake, and intake-outlet installation iron wire or plastics filter are answered, to be controlled.
Six Julys had just been the barbecue busy season, and people can largely ingest spiral shell, and four Mays were exactly spiral shell breeding season, were produced By 2-3 weeks, young spiral shell need to reach constant weight, can ingest, and spiral shell is in great demand at this time, because that need to develop a kind of cultivation side Young spiral shell weight can be improved in method, while in terms of meat taste preferably.
Existing Chinese patent literature (publication number:CN104855309B a kind of cultivation side of man-made pond(pool) spiral shell) is disclosed Method lists in first 30 days in spiral shell;Wherein:10 days early periods the water-soluble oxygen amount of initial monitoring pool, when water dissolved oxygen amount is lower than Aerator is started when 5.0mg/L, and water dissolved oxygen amount is made to be maintained at the critical value or more;Daily early morning, which feeds, increases calcium feed, makes to put down Finished product spiral shell intake in side feeds spirulina liquid at 4 grams or more, and in daily night, make square in finished product spiral shell take the photograph Enter algae amount at 5 milligrams or more;This stage, for water temperature between 20~25 DEG C, which mainly passed through control water dissolved oxygen round the clock Feed is measured and feeds to cultivate spiral shell, and feeding feed is mainly calcium powder, fish meal etc., raising output results are unobvious, It plays a role simultaneously single, it is not good enough to cultivate out spiral shell mouthfeel, yield.
Summary of the invention
The purpose of the present invention is to provide a kind of efficient cultural methods of spiral shell, to solve to propose in above-mentioned background technique The problem of.
To achieve the above object, the present invention provides the following technical solutions:
A kind of efficient cultural method of spiral shell, includes the following steps:
