Embodiment 1

[0031] During fry cultivation, its steps are as follows:

[0032] 1) Disinfection: After treating the dry pond of 1 mu of pond, put 100kg of quicklime into the pond separately, add water until the water depth is 10cm, react with quicklime to get calcium hydroxide, stir evenly, that is, lime water, soak in lime water Disinfect for 7 days.

[0033] 2) Change the water: pump out the lime water in the pond, add water to rinse repeatedly until the pH value is <8, drain the water, and add river water filtered through a 60-mesh sieve to a depth of 60cm.

[0034] 3) Fertilization: Sprinkle 8kg of dry soybeans with water and beat the whole pond, and then evenly sprinkle 8kg of Taifeng brand omnivorous fish feed (Jinfeng Feed Factory) in the whole pond, and compost for 7 days. The color of the water body becomes darker, and the microorganisms in the water body reproduce in large numbers, containing more plankton, especially the opening bait organisms of the water flower seedlings.

Embodiment 2

[0044] During fry cultivation, its steps are as follows:

[0045] 1) Disinfection: After the 1-acre pond is dried, expose it to the sun for 5 days, put 150kg of quicklime into the pond, add water until the water depth is 20cm, obtain lime water, soak the pond with lime water and disinfect it for 14 days.

[0046] 2) Change the water: pump out the lime water in the pond, add water to rinse repeatedly until the pH value is <8, drain the water, and add groundwater filtered through an 80-mesh sieve to a depth of 80cm.

[0047] 3) Fertilization: Sprinkle 12kg of dried soybeans with water and beat the whole pond, then evenly sprinkle 12kg of Taifeng brand omnivorous fish feed (Jinfeng Feed Factory) in the whole pond, and compost for 10 days. After 10 days, the color of the water body became darker, and the microorganisms in the water body multiplied in large numbers, containing more plankton, especially the opening bait organisms of the water flower seedlings.

[0048] 4) Use a mes...

Embodiment 3

[0057] During fry cultivation, its steps are as follows:

[0058] 1) Disinfection: After treating the dry pond of 1 mu of pond, expose it to the sun for 7 days, put 125kg of quicklime into the pond separately, add water until the water depth is 15cm, obtain lime water, soak and disinfect with lime water for 10 days.

[0059] 2) Change the water: Drain the lime water in the pond, add water to rinse repeatedly until the pH value is <8, drain the water, and add new water to a depth of 70cm.

[0060] 3) Fertilization: Sprinkle 10kg of dry soybeans with water and beat the whole pond, and then evenly sprinkle 10kg of Taifeng brand omnivorous fish feed (Jinfeng Feed Factory) in the whole pond, and compost for 8 days. After 8 days, the color of the water body became darker, and the microorganisms in the water body multiplied in large numbers, containing more plankton, especially the opening bait organisms of the water flower seedlings.

[0061] 4) Add 10kg of photosynthetic bacteria ...

Abstract

The invention discloses a night culture method of loach using lamplight. The night culture method of the loach using lamplight includes the steps of sterilization, water change, fertilizer application, addition of photosynthetic bacteria, seed addition, seed raising and the like. During the culturing, night lamplight is used to attract palatable bait (plankton) of fry to gather to pond surface, the palatable bait serves as night prey for the fry, and accordingly no fertilizer is added. The night culture method of loach using lamplight also includes advanced fry culture process. Food intake of the fry increases. A small amount of fertilizer is added during night lighting to promote growth of the advanced fry. The survival rate of the fry of the loach cultured by the night culture method reaches more than 50%, and the survival rate of summerlings reaches more than 90%.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and mainly relates to a method for cultivating loach with lights at night. Background technique [0002] Loach is delicious, tender and nutritious, and is known as "ginseng in water". Loach is rich in protein and multivitamins, with very little fat and cholesterol. It is a high-protein and low-fat food, and loach contains an unsaturated fatty acid similar to eicosapentenoic acid, which is beneficial to the human body's anti-vascular aging, so it is beneficial to Elderly and cardiovascular patients. Loach is also rich in nucleosides, which are the main components of various vaccines and can improve the body's ability to resist viruses. In addition, loach is flat in nature and sweet in taste, and has the effects of nourishing the middle and nourishing Qi, dehumidifying and reducing jaundice, nourishing the kidney and yang, dispelling dampness and stopping diarrhea, warming the spleen and stom...
