Description

Technical Field

[0001] The utility model belongs to the field of artificial breeding of spiny-breasted frogs, and particularly relates to an integrated breeding system for spiny-breasted frogs. Background Art

[0002] The spiny-breasted frog, also known as the stone frog, is an animal of the family Ranidae in the order Anura of the class Amphibia. The frog often inhabits near clear water pits on shady mountains or near waterfalls with stone caves. It likes to live in damp, quiet, less-lighted, near-water-source, shady mountain rock walls in caves. Usually, the frog often lies in the cave entrance or exposes its head above the water surface to breathe and forage. If disturbed, it will quickly dive into the stone cave or under the rock or stone wall or into the water. The stone frog has the habits of living in groups and foraging at night. Often, several or dozens of stone frogs pile together and live in the same place. In a quiet and suitable environment, they also come out of the cave to forage during the day, and the peak period of activity is at night. It is good at jumping and climbing. Usually, its activities are weak and stable. During the peak breeding period, its activities are frequent, and it has behaviors such as calling and dragging.

[0003] In recent years, due to the continuous deterioration of the habitat and the impact of overfishing, the population of spiny-breasted frogs has dropped sharply. Coupled with environmental pollution and unreasonable development of land, the habitats of spiny-breasted frogs are threatened. Therefore, it is urgent to realize the artificial breeding of spiny-breasted frogs.

[0004] Because the living habits of spiny-breasted frogs have high requirements for the natural environment and breeding technology, and have high requirements for bait (generally only eat live bait), and have a long growth cycle (generally 2 - 3 years), and there are many natural enemies. The existing artificial breeding methods of spiny-breasted frogs are not ideal, restricting the development of the spiny-breasted frog breeding industry. Either the free-range artificial breeding method exposed outdoors, such a breeding method is difficult to control, and the survival rate of young frogs to adult frogs is low. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an integrated breeding system for spiny-breasted frogs to overcome the disadvantages of the existing artificial breeding methods of spiny-breasted frogs, such as not being ideal, low yield of spiny-breasted frogs, and difficult to meet the living habits of spiny-breasted frogs.

[0006] The technical solution adopted by the utility model is a spiny-breasted frog breeding system, which includes breeding ponds. A plurality of breeding ponds are arranged in two parallel rows. A fence is provided outside the breeding ponds. A shed is arranged at the top of the fence. The shed is surrounded by light-shielding cloth on all sides and covered with a layer of sunshade net on the top; the breeding ponds are rectangular. Third steps, second steps and first steps are successively arranged from outside to inside and from top to bottom on the opposite sides of the breeding ponds. An inlet is arranged at one end of the breeding pond located at the first step. The inlet is connected to an inlet pipe. An outlet is arranged at the other end. The outlet is communicated with a water level control pipe. The water level control pipe is arranged outside the breeding pond.

[0007] Preferably, the first step is a rectangular pool body with a bottom slope of 9-12° from the water outlet to the water inlet, forming a deep water area for breeding young frogs; the second step is inclined downward from the outside to the inside at a slope of 10-15°, which is a wet area for breeding young frogs; the third step is inclined downward from the wall of the breeding pond to the wet area with a slope of 10-15°, which is a feeding area for breeding young frogs.

[0008] Preferably, frog-blocking plates and flower pots are alternately placed on the third step along the length direction, the frog-blocking plates are in an N-shape, with legs at both ends in contact with the ground of the third step, and calamus is planted in the flower pots.

[0009] Preferably, two foam boards with holes are further provided in the above-mentioned breeding pond, and the two foam boards are placed alternately and the outer sides are in contact with the third step.

[0010] Preferably, a fence is provided around the top of the aquaculture pond wall, and the fence is 1.5-2 m high.

[0011] Preferably, each of the above-mentioned breeding ponds has a water inlet pipe with a switch, which extends into the breeding pond through a water inlet and has an opening facing downward.

[0012] Preferably, the water outlet is connected to a water level control pipe at 90 degrees through a circular pipe, the water level control pipe is in the sewer and the top end is 50-60 cm higher than the bottom of the breeding pond.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] This system can realize the integrated breeding of spiny-chested frog tadpoles, metamorphosis to spiny-chested frog juveniles and adult frogs. This system can breed spiny-chested frog tadpoles to spiny-chested frog adult frogs, avoiding the stress and damage caused by the transfer of spiny-chested frogs and tadpoles during the breeding process, improving the metamorphosis survival rate of spiny-chested frogs, and facilitating feeding and observation of the breeding and growth of spiny-chested frogs, and can remove sick frogs in time. The metamorphosis landing rate is above 70%, and the survival rate of juvenile frogs to adult frogs can be above 75%.

[0015] The breeding of Paa spinosa tadpoles during the metamorphosis period is carried out by adjusting the water level. At this time, the breeding of Paa spinosa begins to transition to the amphibious stage. Based on the tadpole breeding pond, fences are added and two thin foam boards with holes are set in the breeding pond to make them float in the breeding pond of Paa spinosa tadpoles during the metamorphosis period, so that the juvenile Paa spinosa after metamorphosis can climb up to rest at night. Lower the water level of the first step (feeding area) of the breeding pond to expose a part of the dry area to feed the juvenile Paa spinosa after metamorphosis, feed the tadpoles in the water, and feed the juvenile Paa spinosa after metamorphosis on the first step. This can allow the Paa spinosa tadpoles to be directly bred in the original frog pond after metamorphosis, reducing the damage caused during the movement of the juvenile frogs and improving the metamorphosis survival rate of Paa spinosa tadpoles. For the breeding of juvenile Paa spinosa after metamorphosis, lower the water level of the breeding pond to a suitable position, make the entire first step in a dry state, and add foam boards with bottom feet and flower pots to the first step of the breeding pond for the juvenile Paa spinosa to rest. The breeding of adult Paa spinosa is similar to that of juvenile Paa spinosa. After reducing the breeding density, use foam boards with a higher bottom for breeding.

[0021] The following will further explain and illustrate the present invention in conjunction with the drawings of the specification, so as to facilitate better understanding by those skilled in the art.

[0022] Embodiment 1

[0023] As Figures 1-5 shown, a Paa spinosa breeding system includes a breeding pond 1. A plurality of breeding ponds 1 are arranged in two parallel rows. The pool wall of the breeding pond 1 is provided with a fence along the top perimeter, and the fence is 1.5 - 2 m high; there is a wall around the breeding pond 1, and a greenhouse is set at the top of the wall. The greenhouse is surrounded by light-shielding cloth on all four sides and covered with a layer of sunshade net on the top. The breeding pond 1 is rectangular. On the opposite sides of the breeding pond 1, there are a third step 2, a second step 3, and a first step 4 from the outside to the inside and from the top to the bottom in sequence. An inlet 5 is provided at one end of the breeding pond 1 inside the first step 2. The inlet 5 is connected to an inlet pipe 6, and an outlet 7 is provided at the other end. The outlet 7 is connected to a water level control pipe 8, and the water level control pipe 8 is arranged outside the breeding pond 1.

[0024] Specifically, the above-mentioned breeding pond 1 is a rectangular pond body with a length of 7 - 9 m, a width of 4.5 - 5 m, and a height of 0.7 - 1 m. The first step 4 is a rectangular pond body with a length of 6.8 - 8.8 m, a width of 1.8 - 2 m, and a height of 0.7 - 0.75 m. The slope of the bottom from the water outlet 7 to the water inlet 5 is 9 - 12°, forming a deep water area for juvenile frog breeding. The second step 3 has a length of 6.8 - 8.8 m, a width of 0.6 - 0.8 m, and a height of 0.2 - 0.3 m, and slopes downward at an inclination of 10 - 15° from the outside to the inside, serving as a moist area during juvenile frog breeding. The third step 2 has a length of 6.8 - 8.8 m, a width of 1 - 1.2 m, and a height of 0.5 - 0.6 m, and slopes downward from the pool wall of the breeding pond 1 towards the moist area at an inclination of 10 - 15°. Each breeding pond 1 is equipped with a water inlet pipe 6 with a diameter of 0.05 - 0.08 m and a length of 1 - 1.5 m and a switch. The water inlet pipe 6 extends into the breeding pond 1 through the water inlet and has an opening facing downward. The water outlet 7 is connected by a circular pipe with a diameter of 0.15 at 90° to a water level control pipe 8 with a diameter of 0.15 m and a length of 1.2 m. The water level control pipe 8 is located in a sewer with a length of 18 - 20 m, a width of 0.5 - 0.6 m, and a depth of 0.6 - 0.8 m, and its top end is 50 - 60 cm higher than the bottom end of the breeding pond. The water level control pipe 8 mainly controls the water level in the breeding pond 1, drains water into the sewer, and will not flow back into the breeding pond 1, achieving independent water inlet and drainage.

[0025] On the upper edge of the above-mentioned third step 4, frog - blocking plates 9 and flowerpots 10 are placed alternately along the length direction. The frog - blocking plate 9 is in an n - shape, and the two end feet are in contact with the ground of the third step 4. Cattails are planted in the flowerpots 10.

[0026] In the above - mentioned breeding pond 1, there are also two foam boards 11 with a length of 1 - 1.2 m, a width of 0.5 - 0.6 m, and a thickness of 1 - 5 cm and having holes with a diameter of 0.05 m. The two foam boards 11 are placed alternately and the outer sides are in contact with the third step 2.

[0027] After hatching the tadpoles of the spiny - breasted frog, transfer them to the breeding base. After calculating the breeding density, breed the tadpoles of the spiny - breasted frog in the breeding pond. When breeding the tadpoles of the spiny - breasted frog, remove the frog - blocking plates 9 and flowerpots 10 in the breeding pond 1. No additional fence is needed for the entire breeding pond. During breeding, raise the water level to the third step 4 (the feeding area during juvenile frog breeding). At this time, it is convenient to feed the tadpoles of the spiny - breasted frog.

[0028] The tadpole breeding of spiny-chested frog in the metamorphosis period is carried out by adjusting the water level. At this time, the breeding of spiny-chested frog begins to transition to amphibians. A fence is added on the basis of the tadpole breeding pond 1 and two thin foam boards 11 with holes are added in the breeding pond 1 to make it float in the tadpole breeding pond of spiny-chested frog in the metamorphosis period, so that the spiny-chested frog juveniles can climb up to rest at night after metamorphosis. The water level of the first step 2 (feeding area) of the breeding pond is lowered to expose a part of the dry area to feed the spiny-chested frog after metamorphosis, feed tadpoles in the water, and feed the juveniles after metamorphosis on the first step 2. In this way, the spiny-chested frog tadpoles can be directly cultured in the original frog pond after metamorphosis, reducing the damage caused to the juvenile frogs during the movement process and improving the metamorphosis survival rate of the spiny-chested frog tadpoles.

[0029] After metamorphosis, the water level of the breeding pond is lowered to a suitable position for breeding young frogs of spiny chest frogs, and the first step 2 is all in a dry state. A frog-blocking plate 9 with bottom legs and a flower pot 10 are added to the first step 2 of the breeding pond to give spiny chest frogs a rest. The breeding of adult spiny chest frogs is similar to that of spiny chest frogs. After reducing the breeding density, a foam board with a higher bottom is used for breeding. This system can breed spiny chest frog tadpoles to spiny chest frogs, avoiding the stress and damage caused by transferring spiny chest frogs and tadpoles during the breeding process. The metamorphosis survival rate of spiny chest frogs is improved, and it is convenient to feed and observe the breeding growth of spiny chest frogs at the same time, and sick frogs can be removed in time. The metamorphosis landing rate is more than 70%, and the survival rate of young frogs to adult frogs can be more than 75%.

[0030] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
