Embodiment 1

[0029] A culture method for improving rice field eel meat quality, comprising the following steps:

[0030] (1) 8.5 days before stocking, use quicklime 200g / m 2 Splash the disinfection tank, control the water level to 17.5cm, the water temperature to 25.5°C, the oxygen content in the water to 3.5mg / L, pH=6.8, and change the water once every 2.5d;

[0031] (2) Put 55 rice field eels per square meter and soak them with 1.5% salt water before stocking;

[0032] (3) No feeding within 2.5 days of stocking, and feeding twice a day after 3 days. The feed amount was 1.5% of the eel seed weight within 2 weeks, and the feed amount was increased to 2.5% of the eel seed weight after 17.5 days.

[0033] The present embodiment is a breeding method for improving rice field eel meat quality. The step (1) feed is: mix the selenium-added feed in proportion, then add 1% of the total mass of health-care regulator and stir evenly, pulverize to 100 orders, and place in the bag The rotation speed ...

Embodiment 2

[0041] A culture method for improving rice field eel meat quality, comprising the following steps:

[0042] (1) 7 days before stocking, use quicklime 200g / m 2 Splash the disinfection tank, control the water level to 15cm, the water temperature to 23°C, the oxygen content in the water to 2mg / L, pH=6.5, and change the water once every 2 days;

[0043] (2) Put 50 rice field eels per square meter, soak with 1% salt water before stocking;

[0044] (3) No feeding within 2 days of stocking. After 3 days, they were fed twice a day. The amount of feed fed was 1% of the weight of eel seeds within 1 week, and the amount of feed was increased to 2% of the weight of eel seeds after 15 days.

[0045] The present embodiment is a breeding method for improving rice field eel meat quality. The step (1) feed is: mix the selenium-added feed in proportion, then add 1% of the total mass of health-care regulator and stir evenly, pulverize to 100 orders, and place in the bag The rotation speed of t...

Embodiment 3

[0053] A culture method for improving rice field eel meat quality, comprising the following steps:

[0054] (1) 10 days before stocking, use quicklime 200g / m 2 Splash the disinfection tank, control the water level to 20cm, the water temperature to 28°C, the oxygen content in the water to 5mg / L, pH=7.2, and change the water once every 3 days;

[0055] (2) Put 60 swamp eels per square meter, soak with 2% salt water before stocking;

[0056] (3) No feeding within 3 days of stocking. After 3 days, they were fed twice a day. The amount of feed was 2% of the weight of eel seeds within 2 weeks, and the amount of feed was increased to 3% of the weight of eel seeds after 20 days.

[0057] The present embodiment is a breeding method for improving rice field eel meat quality. The step (1) feed is: mix the selenium-added feed in proportion, then add 1% of the total mass of health-care regulator and stir evenly, pulverize to 100 orders, and place in the bag The rotation speed of the coat...

Abstract

The invention discloses a breeding method for improving the quality of ricefield-eel meat. According to growth requirements of ricefield eels, selenium-rich feed for different stages is provided for feeding, rich nutrients are provided for growth development of the ricefield eels, easily-infected disease and parasitic disease in the ricefield-eel breeding process are effectively prevented, the survival rate of artificial breeding of the ricefield eels is increased, the quality and the nutriment content of meat of the ricefield eels are effectively improved, and high-quality selenium-rich ricefield eels are obtained. The selenium-added feed is prepared from spartina alterniflora extract, EM bactericide, fish meal, wheat, soybean meal, soybean oil, monocalcium phosphate, dried earthworms, beer yeast, sleeve-fish visceral meal, kelp meal, salt, carrot powder and selenium methionine.

Description

technical field [0001] The invention relates to the technical field of aquatic animal breeding, in particular to a breeding method for improving rice field eel meat quality. Background technique [0002] Field eel, also known as eel, is a fish belonging to the genus Field Eel in the family Synbranchidae. It often lives in muddy water bottoms such as paddy fields, small rivers, streams, ponds, canals, lakes, etc. It is produced all over China, with the Yangtze River Basin, Liaoning and Tianjin producing more, and the production period is from June to October. -The fattest produced in August. [0003] The eel meat is tender and delicious. The nutritional value is very high. Every 100 grams of eel meat contains 17.2-18.8 grams of protein, 0.9-1.2 grams of fat, 38 mg of calcium, 150 mg of phosphorus, and 1.6 mg of iron; in addition, it also contains thiamine (vitamin B1), riboflavin ( B2), niacin (vitamin PP), ascorbic acid (vitamin C) and other vitamins. Swamp eel is not o...
