Paddy seedlings
Paddlefish are more mature than Chinese sturgeon and Daphnia magna. Male sexual maturity is usually 7-9 years, females are usually 8-10 years, and females are generally selected to produce about 18 kg. Female sex ratio is generally 1:1. Paddlefish broodstock has no obvious side sexual characteristics. In general, female individuals are large, abdominal distension, swollen, congested and slightly loosened near the urogenital port, and easy insertion of the urogenital port with little fingers; male individuals are smaller and have more protrusions on the head. A more reliable method is to observe the gonad with the naked eye.
At present, the effect of oxytocin is better. The pituitary gland and luteinizing hormone-releasing hormone analogue (LRH-A) of the frozen paddlefish are common, and the pituitary gland of the paddlefish is commonly used. The females are generally used in two pituitary/tailed males and males in one pituitary/tail. After thawing the pituitary, 1.5 ml of deionized water was added, and after grinding, it was intraperitoneally injected. The injection method was one needle and the success rate was 65%. With LRH-A oxytocin has a good effect, the dose is generally 10mg per kilogram of body weight, more use of two-needle injection method, the gonads developed better broodstock, basically empty. After promoting estrus in the broodstock, eggs are collected, inseminated, de-adhered, and hatched to obtain fry. It should be noted that 24°C is the sublethal temperature for fry hatching and 28°C is the lethal temperature, while water temperature below 11°C will also reduce the survival rate and inhibit its growth. The optimum water temperature range is 20~24°C. In addition, larval rearing should be carried out indoors to avoid death caused by excessive temperature difference.
2. Seed cultivation
In two stages, the first stage is raised from 2 to 3 cm in length to 6 to 7 cm. Usually hold in the cement tank or cement tank for about 15 days to reach a full length of 6 to 7 centimeters. During the cultivation period, the dissolved oxygen is kept above 6 mg/L. The feed is suitable for feeding, and the amount of bait (mainly Cladocera) is sufficient. Prevent excessive density to avoid self-inflation.
After a total length of 6 to 7 centimeters, it is put into a pond for cultivation. The pond area requires 3 to 5 mu, the water depth is 1.5 to 2 meters, and drainage and irrigation are convenient. Each pool is equipped with a 1.5-kilowatt aerator. Before stocking, the pond water shall be drained and disinfected with quicklime. The amount of mu is 300-400 kilograms to kill miscellaneous fish, aquatic plants, pathogens and predators. The growth temperature can be 2 °C ~ 37 °C can be, the most suitable 25 °C ~ 32 °C, a week before the pond, to do fertilizer to cultivate knife water quality, with green manure or manure. After 3 days, soymilk and slag were sprinkled into the pond, and the amount of 5kg/mu promoted the horny genus. Before the lagoon, it was not necessary to use a net to remove the larvae and other debris.
When stocking, the temperature difference between the fish pond water temperature and the fish container should not exceed 1°C. Operation should be carried out in the evening. The main farming method is monoculture, but sometimes with herbivorous fish, do not match fierce fish, stocking density of 1000 ~ 1500 tail / mu this is good. In the breeding process, in addition to fertilizing and cultivating water quality, soybean milk (2kg/mu), glutinous rice bran and rice bran, or special pellet feed is also fed to maintain the water quality of fertilizer, living, tender and cool.
