Description

Technical Field

[0001] The invention relates to the technical field of giant salamander breeding, in particular to an ecologically simulated high-density and efficient breeding method for giant salamanders. Background Art

[0002] The giant salamander (commonly known as the baby fish) is a national second-class protected animal. It is a subtropical amphibious fish with a wide range of adaptability. 17-30℃ is the optimal growth temperature for the giant salamander. The giant salamander contains more than 70 kinds of natural active organisms, which have unique research and development value in food, medicine, cosmetics, and health food. It can also promote human physiological activity, improve human cell metabolism, promote human protein synthesis, improve human immune function, and enhance human disease resistance. The giant salamander contains an anti-cancer factor that can soften cancer cells, inhibit cancer cell metastasis, and activate the body to produce anti-cancer factors, thereby achieving the purpose of cancer prevention and anti-cancer. The giant salamander can also be used as a traditional Chinese medicine with nourishing and strengthening effects. It can also treat neurasthenia, anemia, and dysentery.

[0003] There are currently two main breeding technologies for giant salamanders: original ecological breeding technology, simulated ecological breeding technology, and factory-based artificial breeding technology. Artificial breeding technology is mature, but most of the current artificial breeding on the market is non-standardized, without temperature control, poor water quality, no circulation, and unsanitary environment, which leads to changes in the skin color of giant salamanders, low quality, and loss of nutritional value, which is not conducive to the healthy development of the industry. The original ecological breeding of giant salamanders has the defects of being too affected by environmental and climatic factors, and the water quality safety in the breeding area cannot be fully guaranteed. Simulated ecological breeding has always been threatened by natural factors and difficult to breed in batches;

[0004] The high-density and efficient breeding method of giant salamanders proposed in the present invention can well solve the technical problems existing in ecological breeding. Therefore, ecological breeding can achieve high-density breeding and high-quality breeding, and will become the standard breeding model of the giant salamander breeding industry. It will promote the industry to develop in a standardized and normalized way. By implementing the high-density and efficient breeding method of giant salamanders, it is possible to protect development opportunities in nature and realize a win-win development path of ecological environmental protection and high-quality economic development.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] like Figures 1 to 4 As shown, the embodiment of the present invention provides a method for high-density and efficient ecological breeding of giant salamanders, including: selecting a site, selecting a stream with cool water quality, requiring lush aquatic plants and many trees on the bank, the water level in the dry season is not less than 40 centimeters, the minimum width of the stream is more than 200 centimeters, the water level in the dry season can be adjusted by building a dam, the stream with lush aquatic plants can provide more plankton, aquatic insects and small invertebrates for giant salamanders to eat, and the cool water quality and the trees on the bank can provide a good habitat and shelter environment for giant salamanders;

[0028] To build a bionic cave, multiple pits are dug on the surface of the riverbed 1 on one side of the stream width direction. The pits are fifty centimeters deep, three hundred and twenty centimeters long, and one hundred and ninety centimeters wide. The multiple pits are spaced in sequence along the length of the stream. A base 2 is placed in the pit. The base 2 is a C20 concrete bottom plate. The upper surface of the base 2 is at the same height as the surface of the riverbed 1. A bionic cave with an opening 6 is built on the upper surface of the base 2. The opening 6 faces the downstream of the stream. A breeding layer 13, a habitat layer 14, and a flood control layer 15 are arranged in sequence from bottom to top in the bionic cave. The internal heights of the breeding layer 13, the habitat layer 14, and the flood control layer 15 are fifty to 60 cm, with the cave entrance 6 facing the downstream of the stream, so that in the event of a flood, there will be no impact on the interior of the bionic cave, release, select healthy giant salamanders aged 1-2 years old from artificially bred giant salamanders for release, and the number of releases is less than the total number of bionic caves in the stream section; management, after release, habitat protection and safety management are carried out, and bait is appropriately supplemented from spring to summer, and live fish or fresh fish are fed. The breeding layer 13 and the habitat layer 14 can be used for giant salamanders to lay eggs and live, and the flood control layer 15 can be used for giant salamanders to hide in the event of a flood, so as to avoid being washed away by the flood and being affected by the poor water quality of the flood;

[0029] The bionic cave is composed of a shell 3, a first layer plate 4 and a second layer plate 5. The shell 3 is fixedly connected to the upper wall of the base 2. The shell 3 is a 10 cm thick C25 reinforced concrete shell. The first layer plate 4 and the second layer plate 5 are fixedly connected to the inner wall of the shell 3 in order from bottom to top. The first layer plate 4 and the second layer plate 5 are both 10 cm thick C25 reinforced concrete partitions. The distance between the first layer plate 4 and the base 2, the distance between the second layer plate 5 and the first layer plate 4, and the distance between the second layer plate 5 and the inner upper wall of the shell 3 are equal. The internal heights of the breeding layer 13, the habitat layer 14 and the flood control layer 15 are between fifty and sixty centimeters, which can provide a relatively spacious living space for the giant salamander.

[0030] The outer wall of the shell 3 is provided with a decorative layer 12, which is 30 cm thick M10 mortar pebbles. By decorating the outer wall of the shell 3 with mortar pebbles, the appearance of the bionic cave is close to the original ecology, making it easier for the giant salamander to accept the artificial bionic cave;

[0031] A breeding layer 13 is formed between the first plate 4 and the base 2, a habitat layer 14 is formed between the second plate 5 and the first plate 4, a flood control layer 15 is formed between the second plate 5 and the inner upper wall of the shell 3, and a hole 6 is arranged on the side of the shell 3 facing the downstream of the stream and is located near the base 2. The width and height of the hole 6 are both 30 cm, and the hole 6 can be used for the giant salamander to enter and exit the bionic cave;

[0032] The lower walls of the breeding layer 13, the habitat layer 14 and the flood control layer 15 are all provided with a protective layer 7, which is a 10 cm thick M10 mortared pebbles. The mortared pebbles make the breeding layer 13, the habitat layer 14 and the lower wall of the flood control layer 15 close to the original ecological environment, and also play a role in protecting the abdomen of the giant salamander;

[0033] A connecting passage is provided between the breeding layer 13 and the habitat layer 14, and between the habitat layer 14 and the flood control layer 15. The connecting passage includes a first ramp 9 and a second ramp 11. The inner wall of the first plate 4 is provided with a first inlet 8 which is through-through from top to bottom, and the inner wall of the second plate 5 is provided with a second inlet 10 which is through-through from top to bottom. The first ramp 9 is provided between the inner lower wall of the breeding layer 13 and the first inlet 8, and the second ramp 11 is provided between the inner lower wall of the habitat layer 14 and the second inlet 10. Both the first ramp 9 and the second ramp 11 are pebble-laid ramps. The first inlet 8 and the second inlet 10 are both 30 cm wide and 40 cm long in top-view projection. The first ramp 9 and the second ramp 11 are used for the giant salamander to move between the breeding layer 13, the habitat layer 14 and the flood control layer 15.

[0034] The edges of the first entrance 8, the second entrance 10 and the hole 6 are all polished to form arc corners. Polishing the corners into arc corners is beneficial to protecting the body of the giant salamander and avoiding bumps and injuries.

[0035] Working principle: The interior of the stream with lush aquatic plants can provide more plankton, aquatic insects and small invertebrates for the giant salamander to eat. The cool water quality and the trees on the shore can provide a good habitat and shelter environment for the giant salamander. The outer wall of the shell 3 is decorated with mortar pebbles to make the appearance of the bionic cave close to the original ecology, making it easier for the giant salamander to accept the artificial bionic cave. The width and height of the cave opening 6 are both 30 cm. The cave opening 6 can be used for the giant salamander to enter and exit the bionic cave. The mortar pebbles make the breeding layer 13, the habitat layer 14 and the lower wall of the flood control layer 15 close to each other. The original ecological environment also plays a role in protecting the abdomen of the giant salamander. The first ramp 9 and the second ramp 11 allow the giant salamander to move between the breeding layer 13, the habitat layer 14 and the flood control layer 15. The edges of the first entrance 8, the second entrance 10 and the hole 6 are all polished to form arc corners. The polishing of the corners into arc corners is beneficial to protecting the body of the giant salamander and avoiding bumps and injuries. The breeding layer 13 and the habitat layer 14 can be used for the giant salamander to lay eggs and live. The flood control layer 15 can be used for the giant salamander to take shelter in the event of a flood to avoid being washed away by the flood and being affected by the poor water quality of the flood.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
