Description

A spawning pond for silver pomfret broodstock

technical field

The utility model relates to a broodstock spawning pool in the field of aquaculture, in particular to a silver pomfret broodstock spawning pool.

Background technique

Silver pomfret is the main marine economic fish in my country, which has high edible value and market prospect. Since the 1980s, domestic scholars have carried out research on its breeding biology. Because silver pomfret broodstock dies immediately out of water, live silver pomfret broodstock cannot be obtained from natural sea areas. At the beginning of this century, researchers have obtained the seedlings of silver pomfret through artificial insemination at sea. Through research in recent years, the parents of artificially cultured silver pomfrets have been successfully bred, and their natural ovulation has been realized. However, because silver pomfrets are easily frightened by external stimuli, the separation of fertilized eggs in broodstock ponds should not be collected in the form of artificial nets. Therefore, on the basis of ensuring the survival rate of fertilized eggs, how to minimize the stress response of silver pomfret broodstock caused by human manipulation is a research content that cannot be ignored. In the separation of fertilized eggs in silver pomfret broodstock ponds, external stimuli are the main factors leading to the stress response of silver pomfret, therefore, a silver pomfret broodstock spawning pond that can minimize artificial manipulation stimulation is needed.

Contents of the invention

The technical problem to be solved by the utility model is to provide a spawning pool for silver pomfret broodstock, so as to collect fertilized eggs and reduce stimulation to silver pomfret broodstock during operation.

The technical scheme adopted by the utility model to solve its technical problems is: provide a kind of silver pomfret broodstock spawning pond, comprise circular cement pond, pot bottom shape pond bottom and sieve tulle bag, described circular cement pond lower end and The bottom of the pot-shaped pool is connected, and two fertilized egg outlets are distributed on the upper end of the circular cement pool; a buffer bucket is provided below each of the two fertilized egg outlets; the sieve tulle bag is bound on The fertilized eggs are discharged from the outlet and suspended in the buffer bucket; the circular cement pool is provided with a water inlet pipe; the upper end of the water inlet pipe is higher than the top of the circular cement pool , and is provided with a water inlet; the bottom of the bottom of the pot-shaped pool is provided with a sewage outlet at the bottom of the pool.

The sewage outlet at the bottom of the pool is arranged at the center of the bottom of the bottom of the pot bottom.

The two outlets for fertilized eggs are symmetrically distributed on the upper end of the circular cement pool.

The water inlet pipe is located on the central axis of the circular cement pool and extends to the bottom of the circular cement pool.

The sieve tulle bag is a 100-mesh sieve tulle bag.

The diameter of the circular cement pool is 6 meters.

The distance between the outlet of fertilized eggs and the top of the wall of the circular cement pool is 20 centimeters.

Beneficial effect

Due to the adoption of the above-mentioned technical scheme, the utility model has the following advantages and positive effects compared with the prior art: the utility model is simple in structure, easy to operate, easy to collect fertilized eggs, and reduces the stimulation to silver pomfret broodstock in the operation process .

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

The embodiment of the present utility model relates to a kind of broodstock spawning pond of silver pomfret, as shown in Figure 1, comprises circular cement pond 1, pot bottom shaped pond bottom 7 and sieve tulle bag 3, wherein, the circular cement pond 1 The diameter is 6 meters, and the sieve tulle bag 3 adopts 100 mesh sieve tulle bags. The lower end of the circular cement pool 1 is connected to the bottom of the pot-shaped pool 7, and the upper end of the circular cement pool 1 is symmetrically distributed with two fertilized egg discharge outlets 2, and a buffer bucket 4 is respectively arranged below the two fertilized egg discharge outlets 2, and the fertilized egg The distance between the outlet 2 and the top of the circular cement pool 1 is 20 centimeters. The sieve tulle bag 3 is bound on the fertilized egg discharge port 2, and is suspended in the buffer bucket 4. The central axis of the circular cement pool 1 is provided with a water inlet pipe 6, the upper end of the water inlet pipe 6 is higher than the top of the circular cement pool 1, and is provided with a water inlet 5, and the water inlet pipe 6 extends to the bottom of the circular cement pool 1 bottom end. The bottom central position of the bottom of the pot-shaped pool 7 is provided with a sewage outlet 8 at the bottom of the pool.

When the utility model is in use, the buffer bucket is filled with seawater, and the 100-mesh sieve tulle bag tied to the outlet of fertilized eggs is placed in the buffer bucket, and seawater is injected into the circular cement pool from the bottom of the pool through the water inlet pipe, which has the advantages of The buoyant silver pomfret fertilized eggs slowly gather in the 100-mesh sieve tulle bag from the fertilized egg outlet. After the collection is over, take off the 100-mesh sieve tulle bag to collect the fertilized eggs, and the water level in the circular cement pool can be adjusted to an appropriate water level by the sewage outlet at the bottom of the pool. It is not difficult to find that the utility model is simple in structure, easy to operate, convenient to collect fertilized eggs, and reduces the stimulation to silver pomfret broodstock in the operation process.
