Description
Technical field
The present invention relates to Rapana venosa seedling-raising technique field more particularly to a kind of Rapana venosa method for culturing seedlings and device.
Background technique
Rapana venosa（Rapana Venosa）Also known as red spiral shell, is the peculiar economic shellfish for living in coastal zone along the Huanghai Sea and the Bohai Sea, and foot is special
Unloose, Fresh & Tender in Texture fertile, full of nutrition, aquaculture has a extensive future.Since Rapana venosa has the cultivation speed of growth fast, support
The advantages of period is short, and premunition is strong, high survival rate, remarkable in economical benefits is grown, the continuous expansion of aquaculture scale is therefore, right
The demand of seed is also more and more, and the red spiral shell nursery in China at present is also in the experimental stage.Since red spiral shell is carnivorous shellfish and Bao
Being a difference in that after abalone attached plate for fish nursery is based on benthic diatom, and is to be with carnivorous bait after red spiral shell attached plate
Main, the bait conversion after attached plate is its technical bottleneck, thus causes Rapana venosa artificial breeding output of seedling extremely low, and industry is not achieved
The level of change can not meet demand of the cultivation unit to seed and develop new seedling raising manners for this technical problem of Rapana venosa
It is the key that put the axe in the helve, while reducing seedling cost.
Therefore, the prior art need to be improved and improve.
Summary of the invention

Piece.
A kind of Rapana venosa method for culturing seedlings, wherein including step：
Rapana venosa kind shellfish is selected, by 10-20/m3It being placed in nursery pond, kind shellfish is daily that food carries out bait throwing in clam son and mussel,
Water is changed, Rapana venosa mates after 3-4 days, and kind of a shellfish is removed after oviposition；
To be hatched within egg capsule 18-25 days under 20-25 DEG C of water temperature veliger, egg capsule after larva all hatches in black again
It sorts out；The young is cultivated by 0.1-0.2/milliliter density cloth pond, changes water, bait throwing in daily, under 23-28 DEG C of water temperature condition, warp
It cultivates within 18-25 days, obtains the initial stage young of 4 gyrations；
In the outdoor ponds that the initial stage young is continued to cultivate, while the Rapana venosa device for raising seedlings being placed in, 7 ~ 10 days
Afterwards, the initial stage larval culture of 4 gyrations is the 4 gyration mid-term young, and the mid-term young is moved in the Rapana venosa device for raising seedlings
In net cage, for settlement and metamorphosis at young spiral shell, abnormal later young spiral shell utilizes is attached to wave to the mid-term young of Rapana venosa after 2-5 days swim
Benthon on card is food, grows to 5mm and strips down later, carries out aquaculture.
The Rapana venosa method for culturing seedlings, wherein the length of the 4 gyration mid-term young is 1200-1400 microns.
Beneficial effect：Rapana venosa device for raising seedlings provided by the invention, including frame and the net cage being fixed in the frame,
The top of the frame is outstanding several floating balls, so that device provided by the present invention, which becomes to float, is placed in outdoor environment water system
In floating installation, provide for the nursery of Rapana venosa closest to natural growing environment and without excessive manual adjustment；It is described
The bottom of net cage is equipped with corrugated plating and tile, and growth attachment place can be provided for benthon, will be in 4 gyrations of Rapana venosa
The phase young is placed in the device for raising seedlings, and the young can adhere to after swimming and metamorphosis is at young spiral shell, and benthon can be eaten by young spiral shell
With, thus the carnivorous minced fillet of artificial feeding is no longer needed to, has both saved cost, more avoid feeding bait and lead to asking for water pollution
Topic, thus young survival rate can be greatlyd improve using device for raising seedlings provided by the present invention cultivation Rapana venosa.

Based on above-mentioned apparatus, the present invention also provides a kind of Rapana venosa method for culturing seedlings, wherein including step：
S1, Rapana venosa kind shellfish is selected in Rapana venosa mating period, by 10-20/m3Be placed in nursery pond, kind shellfish daily with
Clam son and mussel are that food carries out bait throwing in, change water, and Rapana venosa mates after 3-4 days, and Rapana venosa is removed after producing to enough egg capsules
Kind shellfish；
S2, egg capsule 18-25 days under 20-25 DEG C of water temperature are hatched veliger, egg capsule after larva all hatches darkly
Color is sorted out again, obtains Rapana venosa larva；Then larva is cultivated by 0.1-0.2/milliliter density cloth pond, changes water, bait throwing in daily,
Under 23-28 DEG C of water temperature condition, was cultivated through 18-25 days, obtain the initial stage young of 1000-1100 microns of 4 gyrations；
In S3, the outdoor ponds that the initial stage young is continued to cultivate, while the Rapana venosa device for raising seedlings being placed in, 7 ~ 10
After it, the 4 gyration mid-term young that the initial stage larval culture of 4 gyrations is 1200-1400 microns move the mid-term young in described
In the net cage of Rapana venosa device for raising seedlings, the mid-term young of Rapana venosa settlement and metamorphosis after 2-5 days swim is abnormal later at young spiral shell
Young spiral shell is food using the benthon being attached on corrugated plating, grows to 5mm and strips down later, carries out aquaculture.
In the step S3, while continuing the cultivation initial stage young, room that the Rapana venosa device for raising seedlings is placed in
In outer pond, it can guarantee that the initial stage young after continuing to cultivate after 7 ~ 10 days becomes 1200-1400 microns of 4 gyration mid-terms
The young synchronously, on the corrugated plating and tile in net cage adheres to upper enough benthons, can satisfy the edible need of young spiral shell
It asks, the mid-term young is moved into the net cage of the Rapana venosa device for raising seedlings, mid-term young settlement and metamorphosis Cheng Zhi after 2-5 days swim
Spiral shell, then young spiral shell can be directly food with benthon, without manually adding or feeding again carnivorous bait, avoid water quality
Pollution problem, the survival rate after settlement and metamorphosis can greatly improve output of seedling up to 50%, while saving and cultivating the time.
In conclusion described device includes frame and fixation the present invention provides a kind of Rapana venosa method for culturing seedlings and device
Net cage in the frame, the top of the frame is outstanding several floating balls, so that device provided by the present invention, which becomes, to float
The dynamic floating installation being placed in outdoor environment water system, the nursery for Rapana venosa are provided closest to natural growing environment and are not necessarily to
Excessive manual adjustment；The bottom of the net cage is equipped with corrugated plating and tile, and growth attachment ground can be provided for benthon
The 4 gyration mid-term young of Rapana venosa are placed in the device for raising seedlings by point, and the young can adhere to and abnormal at young spiral shell after swimming,
Benthon can be edible by young spiral shell, thus no longer needs to the carnivorous minced fillet of artificial feeding, has both saved cost, more avoid feeding
Bait causes the problem of water pollution, thus can be greatlyd improve using device for raising seedlings provided by the present invention cultivation Rapana venosa
Young survival rate.
It should be understood that the application of the present invention is not limited to the above for those of ordinary skills can
With improvement or transformation based on the above description, all these modifications and variations all should belong to the guarantor of appended claims of the present invention
