Embodiment 1

[0028] A method for cultivating puffer puffer fry in earthen ponds comprises the following steps:

[0029] S1: Pond preparation, use a pond with an area of ​​3-5 mu and a depth of 2 meters as an earthen pond for cultivation, install a microporous aerator in the pond, install 5-6 aeration plates per mu of water surface, and then use quicklime for drying. Method clear pond disinfection, the amount of quicklime is 140 kg / mu;

[0030] S2: Raise water, sterilize the pond for 5-7 days, then enter the pond, filter the water inlet with 80-mesh silk screen, and turn on the microporous aerator when the water depth in the pond reaches 50cm;

[0031] S3: Detoxify the pool water. After raising the water for 2 days, use sodium humate to detoxify the pool water. The dosage of sodium humate is 0.8 kg / mu;

[0032] S4: Water transfer, on the day when the pool water is detoxified, EM bacteria are used for water transfer, and the dosage of EM bacteria is 2 kg / mu;

[0033] S5: Test the wat...

Abstract

The invention provides a method for culturing takifugu obscurus fry in an earth pond. The method comprises the steps of pond preparation, water conserving, pond water disinfection, water diversion, water testing, fry releasing, fertilization, water addition and diversion and food conversion, wherein sodium humate is adopted in the step of pond water disinfection, and 1.2 kg of sodium humate is used per mu of earth; water diversion is conducted by using EM bacteria, and the use amount of the EM bacteria is 2-3 Kg/mu. According to the method for culturing the takifugu obscurus fry in the earth pond, it is not required that takifugu obscurus is cultured to be about 1 cm in a concrete pond and then put into a large pond for culture, the takifugu obscurus can be directly cultured in the earth pond, time and labor are saved, the cost is low, the culture method is simple and easy to understand, technical content requirements are low, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of cultivating puffer puffer fry fry, and in particular relates to a method for cultivating puffer puffer puffer fry fry in an earthen pond. Background technique [0002] Pufferfish obscurus, commonly known as pufferfish. The body is nearly round, the rear gradually becomes thinner, and the caudal peduncle is slightly flattened. It is mainly distributed in the coastal waters of China (East, Yellow Sea, Bohai Sea) and the middle and lower reaches of the Yangtze River. It is a sea and freshwater migratory fish. In spring, the broodstock spawns from the sea against the river, and the juveniles are fattened in the Yangtze River and lakes, and enter the sea in the next spring. Pufferfish obscurus has fresh, tender and plump meat, rich in protein and fat, and is deeply loved by consumers. Tetrodotoxin extracted from puffer ovaries, kidneys, blood and other parts is a high-grade analgesic drug with high analgesia...
