Description

Attachment is bred to field snail

Technical Field

The utility model belongs to the technical field of aquaculture, a an attacher for field snail breeds is related to.

Background

In natural environment, river snails inhabit water areas which are warm in winter and cool in summer, fresh in water quality, slow in water flow and rich in baits, and the river snails are likely to stop eating and colonize in shady and cool places when the water temperature is higher than 30 ℃ and fall into hibernation when the temperature is lower than 8 ℃. The river snail is a male-female variant, the egg is produced in a fetus, the river snail lays eggs in batches, the egg laying time is 4-10 months every year, and the fertilized eggs are produced after the fertilized eggs develop into young snails in a female snail breeding room. The young snails which are just born have swimming ability and agile actions, gradually lose the swimming ability and gradually slow the actions along with the growth and development. River snails adhere to river banks, stones and aquatic plants, scrape and eat microorganisms such as moss on the surface of river snails or filter impurities in the feed water.

At present, market supply and collection of snail seeds and snail seedlings still mainly depend on wild fishing, the breeding technology of the river snails is lagged, the collection of the snail seedlings still adopts a method of breeding the snail seedlings on the spot after natural breeding, and the production efficiency is low; and traditional natural breeding modes such as ponds and the like are influenced by external factors such as weather temperature, bait abundance, precipitation and the like, and untimely collection can reduce the survival rate of the river snails and restrict the development of the river snail industry.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a field snail breeds attachment convenient to collect, improve the survival rate.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

an escargots breeding attachment comprises a positioning plate, a fixing pile and an attachment piece; the fixing piles are distributed and fixed on the plate surface of the positioning plate; the attachment is sleeved on the fixing pile; the attachment comprises a fixed column and a spiral blade; the spiral blade is arranged on the surface of the fixed column; a central pore passage is arranged in the bottom of the fixed column; the inner diameter of the central pore canal is larger than the outer diameter of the fixed pile.

As a further technical improvement, the depth of the central hole is larger than the height of the fixing pile. The attachment is sleeved on the fixing pile through the central hole channel until the bottom surface of the fixing column is in contact with the plate surface of the positioning plate, and the fixing is reliable.

As a further technical improvement, the top of the fixed column is provided with a lifting ring. When the snails are collected, the attachment piece is lifted out through the lifting ring, the field snails attached to the attachment piece are lifted all at once, and the snails are collected after being directly washed by water, so that the operation is convenient and fast.

As a further technical improvement, the above-described helical blade is made of opaque, rough-surfaced plastic. The opaque helical blade can play a good shading effect and help the river snails to safely pass the high-temperature period of cultivation.

During the use, place the locating plate in the breed water of river snail, through on the spud pile of central pore with the attachment piece cover on the locating plate, through increasing or reducing or interval fixed attachment piece, adjust the attachment area to adjust and breed density.

Compared with the prior art, the utility model has the advantages and beneficial effect below:

1. the utility model is different from the traditional catching mode, the viviparidae is attached to the attachment piece by utilizing the habit of the viviparidae, and the collection is convenient and timely; and the three-dimensional space of the aquaculture water body is fully utilized, the attachment area is increased, the number and the interval of the attachment pieces can be flexibly adjusted according to the specification of the aquaculture water body, and the attachment area is conveniently adjusted, so that the aquaculture density is adjusted, the situation that oxygen deficiency is caused due to congestion is avoided, and the yield of the escargots is improved.

2. The utility model discloses when receiving the spiral shell, will adhere to the piece through the pull ring and propose, the field snail that adheres to on the attachment piece is mentioned by one, directly receives the spiral shell after the water-washed, and convenient operation is swift, has improved and has received spiral shell efficiency.

3. The utility model discloses a helical blade is not transparent, can play good shading effect, helps the high temperature that helps the river snail safety to spend the breed, improves the survival rate of field snail.

The attached drawings are as follows:

1-positioning plate, 2-fixing pile, 3-lifting ring, 4-fixing column, 5-helical blade and 6-central pore canal.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example 1:

an escargots breeding attachment comprises a positioning plate 1, a fixing pile 2 and an attachment piece; the fixing piles 2 are distributed and fixed on the plate surface of the positioning plate 1; the attachment is sleeved on the fixing pile 2; the attachment comprises a fixed column 4 and a spiral blade 5; the helical blade 5 is arranged on the surface of the fixed column 4; a central pore passage 6 is arranged in the bottom of the fixed column 4; the inner diameter of the central hole 6 is larger than the outer diameter of the fixed pile 2.

The depth of the central hole 6 is greater than the height of the fixing pile 2. The attachment is sleeved on the fixing pile 2 through the central hole 6 until the bottom surface of the fixing column 4 is contacted with the plate surface of the positioning plate 1, and the fixing is reliable.

During the use, place locating plate 1 in the aquaculture water body of river snail, locate the spud pile 2 on locating plate 1 with the attachment piece cover through central pore 6 on, can be according to aquaculture water body's specification, through increasing or reducing or interval fixed attachment piece, adjust the attachment area to adjust cultivation density.
