Description

Breeding spawning pond with asterias amurensis white fish roe screening function

Technical Field

The utility model belongs to the technical field of breeding spawning ponds, and particularly relates to a breeding spawning pond with a asterias amurensis roe screening function.

Background

The whitefish is commonly called as true whitefish, belongs to the species of cyprinoid, cyprinid, culter subfamily and whitefish, is unique indigenous economic fish of the star cloud lake, but due to the artificial factors such as the change of the surrounding environment of the lake, the invasion of foreign species, excessive fishing and the like, the original ecological system of the lake is destroyed, the population quantity is drastically reduced, and the fish steps into the line of endangered fish. Therefore, the protection of species and the diversity of aquatic organisms is an important work in ecological civilization construction. In actual work, the fact that the native fingerlings to be protected are not only one kind of the salmon, if a culture pond is independently arranged for the salmon, large material resources and financial resources are required to be consumed, and the actual conditions are not met, so that the culture pond is used for raising various native fingerlings to be protected together. During propagation, the asterias amurensis and other fish species lay eggs together at the same time, the asterias amurensis is small in size, the asterias amurensis belongs to small-sized fishes, single asterias amurensis spawn can not be collected, but the asterias amurensis grows slower than other fishes, and the cultivation effect of the asterias amurensis fries is poor. The breeding of the whitefish with the asterias amurensis is greatly influenced, and the roe can be collected only when the whitefish with the asterias amurensis spawns singly in autumn, so that the production capacity of fries of the whitefish with the asterias amurensis is greatly reduced. However, if the single spawning space can be reserved for the asterias amurensis in the pond according to the biological characteristics and propagation habits of the asterias amurensis, the problem that the asterias amurensis in the polyculture pond can successfully spawn and collect spawns can be effectively solved. Therefore, it is necessary to provide a culture pond with a asterias amurensis roe screening function.

Disclosure of Invention

In order to overcome the problems in the background art, the utility model provides the breeding spawning pond with the asterias amurensis roe screening function, so that single asterias amurensis roe can be conveniently collected for breeding, and the breeding production capacity of the fries of the asterias amurensis in the polyculture pond is greatly improved.

In order to achieve the above purpose, the utility model is realized by the following technical scheme:

the utility model provides a breeding spawning pond with a asteroid whitefish spawn screening function, which comprises a mixed breeding pond, a asteroid whitefish spawning pond, an artificial fish nest, a water flow ladder, a water inlet pipe, a water outlet pipe and an aerator, wherein the asteroid whitefish spawning pond and the aerator are arranged in the mixed breeding pond, the asteroid whitefish spawning pond is a rectangular device formed by surrounding a retaining wall with a net structure, the mixed breeding pond is communicated with the water outlet pipe, the artificial fish nest is paved at the bottom of the asteroid whitefish spawning pond, the water flow ladder is obliquely arranged at the outer side of the asteroid whitefish spawning pond, the tail end of the water flow ladder is communicated with the asteroid whitefish spawning pond, and the top of the water flow ladder is communicated with the water inlet pipe.

Preferably, the artificial fish nest is paved by palm and waterweed and compacted by cobbles.

The utility model has the beneficial effects that:

according to the utility model, the asterias amurensis spawning pond is additionally arranged in the polyculture pond, so that the asterias amurensis can spawn alone, single asterias amurensis spawn can be conveniently collected for culturing, and the offspring seed production capacity of the asterias amurensis in the polyculture pond is greatly improved.

Description of the embodiments

In order to make the objects, technical solutions and advantageous effects of the present utility model more apparent, preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.

As shown in figure 1, the breeding spawning pond with the function of screening the asteroid whitefish spawns comprises a mixed breeding pond 1, a asteroid whitefish spawning pond 2, an artificial fish nest 3, a water flow ladder 4, a water inlet pipe 5, a water outlet pipe 6 and an aerator 7, wherein the asteroid whitefish spawning pond 2 and the SR50 Roots aerator 7 are arranged in the mixed breeding pond 1, the SR50 Roots aerator 7 is used for increasing dissolved oxygen, according to the characteristics that the asteroid whitefish is relatively small in size and no fish fry exists in the mixed breeding pond 1, the asteroid whitefish spawning pond 2 is arranged into a pond with a net-shaped structure at the periphery, the size of the net is set into through holes with the diameter of 10cm, only the asteroid whitefish with small size can pass through, the mixed breeding pond 1 is communicated with the water outlet pipe 6, and the water outlet pipe 6 is matched with the water inlet pipe 5 communicated with the water flow ladder 4, so that water in the mixed breeding pond 1 flows circularly, and water quality is ensured. An artificial fish nest 3 is paved at the bottom of the asterias amurensis white fish spawning pond 2, the artificial fish nest 3 is paved by using palm, a water grass handle and the like, cobbles are compacted and fixed to prevent the cobbles from being washed away by flowing water, and the roes of the asterias amurensis white fish are sticky and can be attached to the palm and the water grass handle of the artificial fish nest 3 so as to be convenient to collect. The water flow ladder 4 is obliquely arranged on the outer side of the asterias amurensis white fish spawning pond 2, the tail end of the water flow ladder 4 is communicated with the asterias amurensis white fish spawning pond 2, the water flow ladder 4 is communicated with the water inlet pipe 5, when the asterias amurensis white fish breeds, spring water is injected into the asterias amurensis lake and the river channel to lay eggs upwards, according to the breeding habit, the water flow ladder 4 is arranged in the asterias amurensis white fish spawning pond 2, so that flowing water flows into the water flow ladder 4 with a certain gradient from the water inlet pipe 5 and then flows into the asterias amurensis white fish spawning pond 2 to generate water flow, the asterias amurensis white fish can drill into the asterias amurensis white fish spawning pond 2 to lay eggs in a countercurrent manner, and the spawning eggs of the asterias amurensis white fish in the artificial fish nest 3 can be collected.

The working process of the utility model comprises the following steps: in the breeding season of the whitefish, water flows into the water flow ladder 4 through the water inlet 5 and then flows into the whitefish spawning pond 2 to generate water flow, so that the whitefish with smaller size drills into the whitefish spawning pond 2 to spawn, and other fingerlings with larger size are blocked outside the whitefish spawning pond 2, so that the spawns of the single whitefish are collected for cultivation.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the utility model as defined by the appended claims.
