Abstract

The utility model belongs to cray breeding field provides a laboratory cray breeding hides device that hides yin, and the device includes: a shade box, a bait feeding port for observation and an oxygenation device. The device provides a dark activity space for the crayfishes according to the life habits of the crayfishes. Throw the food through the mouth of feeding, crayfish can be in the dark environment of liking and eat to set up oxygenation device in the mouth position of throwing something and feeding, guarantee that aquatic dissolved oxygen is sufficient, food is difficult for rotting, quality of water environmental stability, reduce the crayfish and lead to dying because of the stress response that the aquaculture environment changes and arouse.

Description

Laboratory crayfish is bred and hides device of shady

Technical Field

The utility model belongs to cray breeding field, concretely relates to laboratory cray is bred and hides device of shady.

Background

In recent years, crayfish breeding has developed very rapidly throughout the country. Taking Hubei province as an example, the culture area of the crayfishes in Hubei province in 2017 reaches 544 ten thousand mu, the yield reaches 63 ten thousand tons, and the total yield of the crayfishes accounts for more than half of 112 ten thousand tons. With the increasing heat of crayfish breeding and the increasing expansion of breeding areas, more and more research institutes are developing research works in the aspects of artificial propagation, feed nutrition, epidemic disease prevention and the like of crayfish. Crayfish in the laboratory was the first step in the successful development of the above-mentioned research work. The crayfish growth is greatly influenced by environmental factors, and the crayfish can be stressed and die due to direct illumination, water quality deterioration and other factors. Therefore, a dark activity space and a good water quality environment are provided for the crayfish in the laboratory, and the method is of great importance for the crayfish culture in the laboratory.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a laboratory crayfish is bred and hides device that shades, and the device can provide a bionical attitude environment for the laboratory is bred the crayfish.

In order to achieve the purpose, the utility model adopts the following technical measures:

a laboratory crawfish breeding shading device, the device comprising: a shade box, a bait feeding port for observation and an oxygenation device;

the shading box is a box body with a lower opening, and a channel opening is formed in the box wall at the opening edge of the box body; the number of the channel openings is more than or equal to 2; an observation ear-throwing opening is arranged at the top of the box body; the oxygen increasing device is inserted from the bait feeding port, and the air outlet of the oxygen increasing device is positioned in the box body;

in the above-described device, preferably, a fixing clip is provided on the rim of the observation bait casting port;

in the above device, preferably, the air outlet of the oxygenation device is parallel to the bottom of the shading box;

in the above device, preferably, the width of the passage port is 20-30cm, and the height is 15-25 cm.

Compared with the prior art, the utility model has the advantages of it is following:

1. the device is small and exquisite in design, applicable in most laboratory turnover case or fish bowl.

2. The shading box is suitable in size, at least 3 crayfishes can be allowed to pass through the shading box in parallel, and death caused by blocked actions of the crayfishes in the shading box is avoided.

3. The device has the effect of shading and accords with the habit of crayfish liking yin. In addition, according to the characteristics that the crayfish is low in ingestion speed and the feed is easy to deteriorate, a fixed bait casting port is designed, and an oxygen increasing device is installed in a water body of a bait casting position, so that the stable water quality is ensured.

4. The device has low cost and high efficiency, and is suitable for large-scale production.

FIG. 2 is a perspective view of the apparatus of example 1;

wherein: 1-a shade box, 2-a bait feeding port for observation and 3-an oxygen increasing device.

Detailed Description

Example 1:

a laboratory crawfish breeding shading device, the device comprising: a shade box 1, an observation bait casting opening 2 and an oxygenation device 3;

the shading box is a box body with a lower opening, and a channel opening is formed in the box wall at the opening edge of the box body; the number of the channel openings is 4, the width of the channel openings is 30cm, and the height of the channel openings is 25 cm; an observation ear-throwing opening is arranged at the top of the box body; an oxygen pipe of the oxygenation device is inserted from the observation bait casting port, and is fixed on the port edge by a fixing clamp on the port edge of the observation bait casting port, and an air outlet of the oxygenation device is positioned in the box body and is parallel to the bottom of the shading box; the oxygenation device is an oxygen pump.

The utility model discloses a use as follows:

the crayfish breeding shading device is placed in the turnover box in the laboratory, and water for crayfish breeding is injected into the turnover box, so that the water submerges the air outlet of the oxygenation device, and the total water body height is not more than 15 cm. And (4) opening the oxygenation device, and putting in crayfishes, so that the crayfishes can be cultured in the laboratory.
