Description

Technical Field

[0001] The present invention relates to the technical field of goldfish breeding, and particularly relates to a breeding method for telescope-eye goldfish. Background Art

[0002] The history of goldfish breeding in China is long. With the continuous improvement of people's living standards, goldfish have entered thousands of households as pets. As ornamental fish, people mainly judge their quality from aspects such as body shape, breed characteristics, body color, patterns, and swimming postures.

[0003] Telescope-eye goldfish is a precious variety among goldfish, also known as "upward-facing eye, dragon-looking sky, upward-facing dragon, top telescope eye". Its eyeballs protrude outside the eye sockets like those of dragon-eye goldfish. When swimming in water, the pupils are bright, making it more majestic than dragon-eye goldfish. The wonder of this fish lies in its eyes always looking upward. The most important viewing point of telescope-eye goldfish is that its eyes look upward and the whole is harmonious and beautiful. Therefore, the coordination between the size of its eyeballs and the whole is particularly important; there are also individual aesthetic differences in the market. For example, some people especially like telescope-eye goldfish with large eyeballs, thinking they look more majestic, while others like telescope-eye goldfish with a more coordinated overall proportion. In view of this, it is urgent to develop a breeding method that can regulate the size of its eyeballs and the overall proportion to meet the market demand. Summary of the Invention

[0004] The purpose of the present invention is to provide a breeding method for telescope-eye goldfish, which regulates the proportion of the eyeballs of telescope-eye goldfish in the whole by adjusting the breeding environment of telescope-eye goldfish.

[0005] The present invention provides a breeding method for telescope-eye goldfish, which is divided into an incubation stage, a first cultivation stage, and a second cultivation stage, and includes the following steps:

[0006] 1) Incubation stage;

[0007] Carry out reproduction and incubation on telescope-eye goldfish;

[0008] 2) First cultivation stage;

[0009] After the fry start to feed, gradually and slowly raise the temperature of the breeding water body from normal temperature until the preset temperature is reached, and maintain the preset temperature for breeding;

[0010] 3) Second cultivation stage;

[0011] After breeding for a preset time, when the proportion of the eyeballs of telescope-eye goldfish in the whole reaches the preset proportion, gradually and slowly lower the temperature of the breeding water body until it reaches normal temperature.

[0012] Through actual experimental breeding and observation, it was found that: as the high-temperature breeding time increased, the proportion of the eyeballs of telescope goldfish in the whole body gradually increased, and was extremely significantly larger than that of telescope goldfish bred at normal temperature (P < 0.01); when the high-temperature breeding gradually returned to normal temperature, the proportion of the eyeballs of telescope goldfish in the whole body no longer increased significantly, but maintained the eyeball proportion at the time when the high temperature was stopped. According to this rule, a method for regulating the proportion of the eyeballs and the whole body of telescope goldfish by controlling the temperature of the breeding water body was developed.

[0013] According to the breeding method of telescope goldfish provided by the present invention, the preset temperature in the first cultivation stage is 29°C to 32°C. Breeding telescope goldfish at this temperature can effectively increase the proportion of the eyeballs of telescope goldfish in the whole body on the basis of ensuring the survival rate.

[0014] According to the breeding method of telescope goldfish provided by the present invention, the preset proportion in the second cultivation stage is 6%. When the proportion of the eyeballs of telescope goldfish in the whole body reaches 6%, the whole body of telescope goldfish looks more coordinated and is more popular.

[0015] According to the breeding method of telescope goldfish provided by the present invention, the preset breeding time required in the first cultivation stage is 2.5 to 3 months. After breeding telescope goldfish at high temperature for 2.5 to 3 months, the proportion of the eyeballs of most telescope goldfish in the whole body can reach the required proportion.

[0016] According to the breeding method of telescope goldfish provided by the present invention, in the first cultivation stage and the second cultivation stage, the dissolved oxygen in the breeding water quality is greater than 5mg / L, the turbidity is less than 15, and the ammonia nitrogen is less than 0.5mg / L.

[0017] According to the breeding method of telescope goldfish provided by the present invention, in the first cultivation stage and the second cultivation stage, the daily feeding amount of telescope goldfish is based on the amount that telescope goldfish of the same age can finish eating in 10 - 20 minutes at normal temperature, and only one feeding is carried out every day. In order to ensure the overall size of telescope goldfish and at the same time ensure the proportion of the eyeballs of telescope goldfish in the whole body, the bait amount of high-temperature telescope goldfish is reduced to be the same as that in normal breeding, and the bait amount is preferably 1 - 4% of the fish body weight.

[0018] According to the breeding method of telescope goldfish provided by the present invention, like normal temperature breeding, in the first cultivation stage and the second cultivation stage, defective products with deformed tails, poor dorsal shapes, and unequal eye sizes are periodically eliminated.

[0019] According to the breeding method of telescope goldfish provided by the present invention, after the second cultivation stage, individuals with the eyeballs of telescope goldfish flipped to the standard 90° can be sold as high-quality commercial fish. Some individuals that have not been successfully flipped can be re-bred at normal temperature for about 1 - 2 months until they are successfully flipped and then sold as high-quality commercial fish.

[0020] According to the breeding method of telescope-eye goldfish provided by the present invention, in the first cultivation stage, the temperature of the breeding water body is gradually and slowly increased by 1°C every day until the preset temperature is reached. Such treatment in the first cultivation stage is to prevent the breeding water temperature from fluctuating too much, causing stress to the seedlings due to their inadaptability, and thus increasing the mortality rate. By gradually increasing the temperature of the breeding water body, it is possible to effectively increase the proportion of the eyeballs of the telescope-eye goldfish in the whole body on the basis of ensuring the survival rate and health of the fish.

[0021] According to the breeding method of telescope-eye goldfish provided by the present invention, in the second cultivation stage, the temperature of the breeding water body is gradually and slowly decreased by 1°C every day until the normal temperature is reached. In the second cultivation stage, to prevent the breeding water temperature from being too large, causing stress to the goldfish due to their inadaptability and increasing the mortality rate, by adopting this slow and gradual cooling method, it is possible to effectively regulate the proportion of the eyeballs of the telescope-eye goldfish in the whole body on the basis of ensuring the survival rate and health.

[0022] The specific technology is as follows. Telescope-eye goldfish are artificially bred at room temperature, and the fertilized eggs are incubated conventionally. Starting from the opening of the fry, the temperature of the breeding water body is slowly increased by 1°C every day from the normal temperature until the temperature reaches 30°C. Such slow temperature increase is mainly to prevent the water temperature from fluctuating too much and causing stress to the seedlings, resulting in an increase in the mortality rate. After that, pay attention to maintaining the breeding water temperature between 29 - 32°C, and flexibly change the water according to the water quality situation to adjust the water quality, so as to keep the dissolved oxygen in the water body greater than 5 mg / L, the turbidity less than 15, and the ammonia nitrogen less than 0.5 mg / L. During this period, control the feeding amount, and feed about the amount that can be eaten up by the telescope-eye goldfish cultured at normal temperature in 20 minutes every day, and only feed once a day. During the breeding period, like the normal temperature breeding, regularly eliminate defective products with deformed tails, poor dorsal shapes, and unequal eye sizes. Generally, according to the current market aesthetics, when the proportion of the eyeballs of the telescope-eye goldfish in the whole body is about 6%, the whole looks more coordinated and is more popular. According to the test results, when cultured according to this method for about 2.5 - 3 months, the proportion of the eyeballs of the telescope-eye goldfish in the whole body can reach 6%. At this time, it is necessary to slowly cool down, about 1°C per day, until the normal temperature is reached. At this time, individuals with the telescope eyes flipped to the standard 90° can be selected and sold as high-quality commercial fish. Some individuals that have not been successfully flipped can be cultured at normal temperature for about 1 - 2 months until they are successfully flipped, and then sold as high-quality commercial fish.

[0023] In addition, among goldfish enthusiasts, there are also some who like telescope-eye goldfish with large eyeballs. At this time, the cultivation mode at the temperature of 29 - 32°C above can be extended for more than 3 months until the proportion requirement of the eyeballs of the telescope-eye goldfish liked by the goldfish enthusiasts is reached, and then slowly cool down by 1°C every day until the normal temperature is reached. At this time, when sold as commercial fish, it can meet the needs of goldfish enthusiasts who like telescope-eye goldfish with large eyeballs.

[0024] The breeding method of telescope-eye goldfish provided by the present invention divides the breeding stage of telescope-eye goldfish into an incubation stage, a first cultivation stage and a second cultivation stage. This goldfish breeding method mainly realizes the regulation of the eyeball size and overall proportion by controlling the temperature of the breeding water body, and is simple and easy to implement in actual breeding. Through this breeding method, the expected effect can be achieved in actual breeding. The cultivated telescope-eye goldfish can meet the aesthetic needs of the market. At the same time, this provides basic experimental materials for the research on the eye development of telescope-eye goldfish, and can also lay a foundation for its use as a model animal for the research on human eye-related diseases. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to more clearly illustrate the technical solutions in the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0026] Figure 1 It is a flow schematic diagram of the breeding method of telescope-eye goldfish provided by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0028] The breeding method of telescope-eye goldfish provided by the embodiments of the present invention, as Figure 1 shown, the breeding method of this telescope-eye goldfish includes the following steps:

[0029] 1) Incubation stage;

[0030] Step 1: Breed and incubate the telescope-eye goldfish;

[0031] 2) First cultivation stage;

[0032] Step 2: After the fry start to feed, gradually increase the temperature of the aquaculture water body slowly from room temperature until the preset temperature is reached, and maintain the preset temperature for cultivation; the preset temperature in the first cultivation stage is 29°C to 32°C. Cultivating telescope goldfish at this temperature can effectively increase the proportion of the eyeballs of telescope goldfish in the whole body on the basis of ensuring the survival rate. The preset cultivation time required for the first cultivation stage is 2.5 to 3 months. After cultivating telescope goldfish at high temperature for 2.5 to 3 months, the proportion of the eyeballs of most telescope goldfish in the whole body can reach the preset proportion. During the entire first cultivation stage, defective products with deformed tails, poor dorsal shapes, and unequal eye sizes are eliminated irregularly.

[0033] In the first cultivation stage, the temperature of the aquaculture water body is gradually increased by 1°C every day until the preset temperature is reached. In the first cultivation stage, to prevent excessive temperature difference in the water body and the increase in mortality caused by stress in the seedlings, the method of slow and gradual temperature increase is adopted, which can effectively increase the proportion of the eyeballs of telescope goldfish in the whole body on the basis of ensuring the survival rate.

[0034] 3) The second cultivation stage;

[0035] Step 3: After cultivating for the preset time, when the proportion of the eyeballs of telescope goldfish in the whole body reaches the preset proportion, gradually and slowly reduce the temperature of the aquaculture water body until it reaches room temperature. The preset proportion in the second cultivation stage is 6%. When the proportion of the eyeballs of telescope goldfish in the whole body reaches 6%, the whole body of telescope goldfish looks more coordinated and is more popular. The temperature of the aquaculture water body is gradually and slowly reduced by 1°C every day until it reaches room temperature. In the second cultivation stage, to prevent excessive temperature difference in the aquaculture water body and the increase in mortality caused by stress in goldfish, the method of slow and gradual temperature reduction is adopted, which can effectively regulate the proportion of the eyeballs of telescope goldfish in the whole body on the basis of ensuring the survival rate. During the entire second cultivation stage, defective products with deformed tails, poor dorsal shapes, and unequal eye sizes are eliminated irregularly.

[0036] In the first cultivation stage and the second cultivation stage, the dissolved oxygen in the aquaculture water body is greater than 5mg / L, the turbidity is less than 15, and the ammonia nitrogen is less than 0.5mg / L. The daily feeding amount of telescope goldfish is based on the amount that telescope goldfish of the same age can finish eating the feed in 10 - 20 minutes under room temperature cultivation, and only one feeding is carried out every day. In order to ensure the overall size of telescope goldfish and at the same time ensure the proportion of the eyeballs of telescope goldfish in the whole body, the food intake of telescope goldfish at high temperature is reduced, which is the same as the bait amount during normal cultivation. It is found that it is better when the bait amount is 1 - 4% of the fish body weight.

[0037] After the second cultivation stage, select individuals with the eyeballs of telescope goldfish turned into a standard 90°, which can be sold as high-quality commercial fish. Some individuals that have not been successfully turned can be cultured at room temperature for about 1 - 2 months until they are successfully turned, and then sold as high-quality commercial fish.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below. The telescope goldfish broodstock in the following embodiments are from the telescope goldfish conservation population cultured in the Xiaotangshan Breeding Base of the Institute of Aquatic Sciences, Beijing Academy of Agriculture and Forestry Sciences.

[0039] The feeds used in the following embodiments are as follows: Live hatched brine shrimps are used as the first feed; for about 2 weeks, frozen small multi-vitamin red worms are fed; at one month old, pellet feeds with a diameter of 0.5 - 1.0 mm are fed; after 2 months old, pellets with a diameter of 2.0 mm are fed. The pellet feeds are all purchased from Sanyou Chuangmei Company.

[0040] Example 1

[0041] The experiment was carried out at the Xiaotangshan Breeding Base of the Institute of Aquatic Sciences, Beijing Academy of Agriculture and Forestry Sciences. Telescope goldfish cultured in the base were selected for artificial reproduction. Before the hatching stage, first, 3-year-old male and female broodstock with obvious variety characteristics, strong physique, and no diseases were selected as the breeding broodstock; artificial wet insemination was adopted, with a male-female ratio of 1:2, and the fertilized eggs were hatched naturally in the conventional way.

[0042] After hatching, when the fry start to feed, the temperature of the breeding water body is gradually and slowly increased by 1°C every day from the normal temperature until the temperature of the breeding water body reaches 30°C. The slow heating method is mainly to prevent excessive temperature difference in the water body and the increase in mortality rate caused by stress in the seedlings. After that, pay attention to maintaining the breeding water temperature at 29 - 32°C, and flexibly change the water according to the water quality situation to adjust the water quality, so as to keep the dissolved oxygen in the water quality greater than 5 mg / L, the turbidity less than 15, and the ammonia nitrogen less than 0.5 mg / L. During this period, control the feeding amount, and feed about the amount that can be eaten by the same-age telescope goldfish cultured at normal temperature in 20 minutes every day, and only feed once a day. During the breeding period, defective products with deformed tails, poor dorsal shapes, and unequal eye sizes are eliminated irregularly. Generally, according to the current market aesthetics, when the proportion of the eyeballs of the telescope goldfish in the whole body is about 6%, the overall proportion is coordinated and favored by the market.

[0043] According to the test results, after culturing according to this method for about 2.5 - 3 months, the proportion of the eyeballs of the telescope goldfish in the whole body can reach 6%. At this time, slowly cool down, about 1°C per day, until the normal temperature is reached. Select individuals with the telescope goldfish eyeballs flipped to the standard 90°, which can be sold as high-quality commercial fish. Some individuals that have not been successfully flipped can be cultured at normal temperature for about 1 - 2 months until they are successfully flipped, and then sold as high-quality commercial fish.

[0044] Example 2

[0045] The experiment was carried out at the Xiaotangshan Fine Breed Breeding Base of the Fisheries Research Institute of Beijing Academy of Agriculture and Forestry Sciences. The same group of Telescope Eye Goldfish cultured in the base was used as broodstock for reproduction and hatching. When the fry just started to feed, about 600 tails were taken and evenly divided into two groups, with three parallel replicates in each group.

[0046] The first group of Telescope Eye Goldfish was the normal temperature group and was cultured at room temperature. The water quality was adjusted by flexible water change according to the water quality situation to keep the dissolved oxygen in the water quality greater than 5 mg / L, the turbidity less than 15, and the ammonia nitrogen less than 0.5 mg / L. During this period, the daily feeding amount was based on the amount that the fish could finish eating within 20 minutes, and only one feeding was carried out every day. During the breeding period, defective products with deformed tails, poor dorsal shapes, and unequal eye sizes were eliminated irregularly.

[0047] The second group of Telescope Eye Goldfish was the high temperature group and was cultured by heating with a heating rod. After the fry started to feed, the temperature of the culture water body was slowly increased by 1 °C every day from the normal temperature until the temperature reached 30 °C. After that, the overall culture water temperature was maintained at 29 - 32 °C, and the water quality was adjusted by flexible water change according to the water quality situation to keep the dissolved oxygen in the water quality greater than 5 mg / L, the turbidity less than 15, and the ammonia nitrogen less than 0.5 mg / L. During this period, the feeding amount was controlled, and the daily feeding was about the amount that the Telescope Eye Goldfish in the first group cultured at normal temperature could finish eating within 20 minutes, and only one feeding was carried out every day. During the breeding period, defective products with deformed tails, poor dorsal shapes, and unequal eye sizes were eliminated irregularly.

[0048] During the four - month culture of the two groups of Telescope Eye Goldfish, about 10 tails were randomly taken from each group of fish every month. After weighing the body weight, the eyeballs were removed and weighed, and the eyeball / body weight was calculated. Through apparent observation and combined with the index data of eyeball / body weight, the eyeball size and the overall proportion were compared.

[0049] Example 3

[0050] Continuing the experiment based on the above Example 2, the first group of Telescope Eye Goldfish and the second group of Telescope Eye Goldfish were cultured for another 8 months.

[0051] Among them, the first group of Telescope Eye Goldfish was cultured at room temperature and was the normal temperature group; the water quality was adjusted by flexible water change according to the water quality situation to keep the dissolved oxygen in the water quality greater than 5 mg / L, the turbidity less than 15, and the ammonia nitrogen less than 0.5 mg / L. During this period, the feeding amount was controlled, and the daily feeding was based on the amount that the Telescope Eye Goldfish could finish eating within 20 minutes, and only one feeding was carried out every day. During the breeding period, defective products with deformed tails, poor dorsal shapes, and unequal eye sizes were eliminated irregularly.

[0052] The second group of goldfish were heated with heating rods to maintain the water temperature at 29-32℃. The water quality was adjusted by changing water flexibly according to the water quality to keep the dissolved oxygen greater than 5mg / L, the turbidity less than 15, and the ammonia nitrogen less than 0.5mg / L. During this period, the feeding amount was controlled, and the amount of feed was about the amount that the first group of goldfish cultured at room temperature could finish in 20 minutes, and only fed once a day. During the breeding period, defective products with deformed tails, poor back shapes, and unequal eye sizes were eliminated from time to time.

[0053] After the two groups of goldfish were raised for the second year, 10 fish were randomly selected from each group. After weighing their body weights, their eyeballs were removed and weighed, and the eye weight / body weight was calculated. The eye size and overall proportion were compared through visual observation combined with the eye weight / body weight index data.

[0054] The comparison of eye weight / body weight between the two groups at each stage was performed using one-way analysis of variance. A P value of less than 0.05 indicated a significant difference, and a P value of less than 0.01 indicated an extremely significant difference. The results were expressed as mean ± standard error.

[0055] Table 1 Statistical comparison of eye weight / body weight*100% of two groups of goldfish at different ages under different breeding conditions

[0056]

[0057] The results showed that the proportion of eyeballs in the high temperature group was significantly larger than that in the normal temperature group at each stage. The specific data are shown in Table 1. After visual observation, the proportion of eyeballs in the high temperature group was also larger than that in the normal temperature group at each stage. As the breeding time increased, the proportion of eyeballs gradually increased.

[0058] Example 4

[0059] The experiment was continued in the above embodiment 3, and then the high temperature group was further divided into two groups, one of which gradually recovered to normal temperature, slowly reduced by 1°C every two days, until it was completely restored to normal temperature, and then the heating was stopped; the remaining two groups continued to maintain 29-33°C. Half a year later, it was observed that the eyeballs of the goldfish kept at a high temperature of 29-33°C were still growing, but the overall proportion was not coordinated, and the large eyeballs made people uncomfortable; the proportion of their eyeballs in the whole was obviously larger than that of the group restored to normal temperature; the eyeballs of the group restored to normal temperature no longer seemed to increase with the overall increase, and the overall proportion was coordinated. Therefore, the development phenomenon of the eyes of the goldfish can be used as scientific research material, and further research can be carried out on it to explore the deep reasons why high temperature causes the eyeballs to enlarge, and provide model materials for the study of human eye-related diseases.

[0060] According to the above experimental results, according to market and scientific research needs, appropriate proportions of goldfish can be selected as commercial fish or scientific research experimental fish models during appropriate high-temperature breeding periods.

[0061] In summary, the breeding method of telescope goldfish provided by the embodiments of the present invention divides the breeding stage of telescope goldfish into an incubation stage, a first cultivation stage, and a second cultivation stage. This goldfish breeding method mainly realizes the regulation of the eyeball size and overall proportion by controlling the temperature of the breeding water body, which is simple and easy to implement in actual breeding. Through this breeding method, the expected effect can be achieved in actual breeding. The telescope goldfish bred can meet the aesthetic needs of the market. At the same time, this provides basic experimental materials for the research on the eye development of telescope goldfish, and can also lay a foundation for its use as a model animal for the research of human eye-related diseases.

Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
