1?Materials and methods
1.1? Domestication
1.1.1? Domestication Pond
?? Test domesticated pond area of ​​2000 ~ 3333m2, water depth of 1.5m, aquatic plants planted in shallow water pond, quiet environment, built around the pond "T' type escape wall, the pond to the north facing south side to build a 20m2 spawning field A rain-proof shady stone shed is set up on the sand field. The middle of the pond is separated by 2m to build a wooden drying platform and food table. The water surface is planted with Eichhornia crassipes (the total area is 1/5 of the water surface).
1.1.2? Mountain Rui source?
?? From the mountains or the market to buy weight 1 ~ 2kg, no injury-free, robust, no deformity, skin light, thick and strong back skirt edge, and strong, quick action wild mountain Rui.
1.1.3 feed and domesticated food
??????????????????????????????????????????????????????????????????combined feed uses the market full-price to mix the forage feed, the animal feed uses the fresh fish, the snail meat and the small shrimp mainly, the animal feed is soaked in 5% brine for 15 to 20 minutes and then washed with water. Taming the food using a small number of multi-point method, on the table 5cm away from the waterside animal feed to attract food, 18:00 at 18:00 daily, the first 2d morning to remove residual food. By the 8th day, Sanriru began to crawl on the food platform. After the 15th day, the domestication process was basically over. Shan Ruiji had adapted to the food on the food table. At this time, he went into normal feeding and fed it every day. The amount of 3% to 5% of body weight was fed in the morning and evening, and the feed was gradually fed at full price, supplemented with animal feed, and a small amount of green feed was added.
1.1.4? Daily management and disease prevention
?? According to the "four definite" principle of feeding and management, more observations, and earnestly make the relevant records. Domestic ponds are regularly filled with fresh water to remove residual food in a timely manner to keep the water fresh. Strengthen diarrhea prevention and control, every 20 days with conventional disinfectants such as dibromohydantoin, complex iodine or quicklime 10 ~ 15kg/667m2 into lime milk Quanchiposa uniform disinfected once, while feeding antibiotic baits, once a day, even Hello 3d.
1.2 breeding and hatching
1.2.1? Intimate cultivation
In November, the selection of physically robust Shanrui (♀:♂=3:1) from the domestication ponds was used as artificial breeding progeny to move into the nursery pond for cultivation. Intimate breeding ponds have plastic film insulation sheds. The cultivation pond area is 260m2, the brickwork structure, inside the block, the bottom of the pool is placed with 20cm thick yellow mud, the water depth is 1m, and there is a food table and sun drying platform. A 20m2 spawning sand field is built at one end of the pool. Keep the temperature of the water in the boiler at 25°C or so, feed it with animal feed, and feed the full price with cockroach feed and green feed. Strengthen water quality management and disease prevention, and apply photosynthetic bacteria once a month.
1.2.2 mating and spawning
Under artificially controlled temperature conditions, Shan Rui's relatives can mate at water temperatures of 22°C to 25°C, and 15 to 20 days after mating, females start spawning. The spawning takes place in the middle of the night. The female cubs climb onto the battlefield to find a good position, dig nests for spawning, and cover up after laying eggs.
1.2.3? Artificial incubation
10 to 15m2 incubator room, covered with heat-insulating foam board on the four walls and the top, built a small ditch along the wall and injected water and a little fine sand; hang a UV lamp for disinfection and sterilization, use an electric furnace to raise the temperature, use a constant temperature The appliance controls the furnace to control the room temperature.
After 3 days of pro-spawning, fertilized eggs are collected in the hatchery and packed. The method is: first in the bottom of the wooden box 50cm40cm15cm supplemented with 3cm thick hatching sand, then according to the egg spacing 1cm, the animal pole (white point) upwards to release a good fertilized egg, and then cover the hatching sand 10cm, placed on the iron frame, Manual temperature control for incubation. The hatching sand must be screened, contaminated, disinfected and exposed to sunlight to adjust the humidity of the sand (the humidity is 4% to 5%, that is, it is appropriate to disperse it by hand after loosening it by hand). After about 60 days of hatching, the juvenile can hatch out.
During the incubation process, strictly control the room temperature at 302 °C, and control the indoor air humidity at 80% to 85%, to maintain the humidity of hatching sand.
2 results
2.1? Domestication results
In the domestication trials, a total of 964 wild mountain raccoons were purchased, including 703 females and 261 males, with a ratio of 2.7 to 1. After more than two years of domestication trials, the number of acceptances for Ruitang in Cangtang Mountain was 800, and the survival rate was 83.0%. Among them, 623 were females in the pond, and the survival rate was 88?6%; 187 of the males in the pond had a survival rate of 71.6%.
2.2? Egg production rate
According to observations, April and May (Guangzhou-Guangxi area) were the peak period for spawning of Sanrethi, and spawning was basically completed by the end of June. Shan Ruiqi only spawns eggs once a year. In the first year of the trial, females spawned 218 nests, and 309 females entered the nursery pool. The egg production rate was 70.6%.
2.3? Fertilization rate?
According to records, the number of spawnings of Shan Ruiqi is 5 to 20 pieces/fowl, and the majority is 10 to 18 pieces/fowl, with an average of 15.6 pieces/fowl. A total of 3,480 eggs were collected from 218 litters, of which 1,378 were fertilized eggs and the fertilization rate was 39.6%. In terms of oviposition per litter, the minimum fertility rate was 22.3% and the highest fertilization rate was 46.8%.
2.4? Hatching rate
1378 fertilized eggs hatched into the hatchery were hatched after about 60 days, and 12,25 hatchlings were hatched. The hatching rate was 88.9%. Of these, 2 were malformed, accounting for 0.2%.
3 Discussion
3.1? Morphological characteristics
Through observation, it is concluded that the external morphological features of Shanruiqi are: flat and round in shape, with a wide and thick skirt at the back of the body, and a distinct row of granular pods arranged regularly on the front edge of the carapace. The scattered, granular pods are grayish-white on the ventral side and have more black cloud spots. There are lumps on both sides of the base of the neck and the skin is rough.
3.2? Ecological characteristics
Through observation, investigation, and research, it is believed that Shan Ruixin likes to live in a stream. He particularly likes to live in streams with a trickle and quiet environment. It is mainly eaten with animal foods such as snails, clams, fish, shrimp and insects. Plant foods. The suitable water temperature for growth is 20°C to 32°C, and the optimal water temperature for growth is 25°C to 32°C. When the water temperature is below 12°C, hibernation begins. During hibernation, activities and feeding are performed as long as the water temperature rises above 18°C. Shan Ruiqi is docile, has a timid nature, and is slow in action. His back and spawning are all closer to the water.
3.3? Domestication situation
From the results of domestication, the survival rate of males is lower than that of females. According to the analysis, the main reason may be that males are sexually aggressive and injured, causing various diseases to die.
3.4 oviposition
In the first year of the trial, the egg production rate reached 70.6%, which is relatively normal. Some females may not have reached the maturity requirement.
3.5? Fertilization rate
The low fertilization rate may be related to the reason that the cultivation environment does not meet the requirements of Sanrethi ecological environment, or the nutrition of the feed does not meet the requirements of innate breeding. For further study.
3.6? Hatching rate
According to the hatching of Chinese sturgeon, the hatchling can be hatched after about 60 days when the hatching sand has a maximum particle size of 0.5 mm, a relative humidity of 4% to 5%, and an average temperature of 30°C. 88.9%. I believe that the normal level of incubation has been reached.
Since this is the first year of the trial, many aspects of domestication and breeding are still being explored. We will sum up experience and further explore the artificial domestication and breeding techniques of wild wild lycium, providing technical support for large-scale domestication and reproduction.
