Embodiment 1

[0011] A kind of loach soilless culture method, it is characterized in that: build culture pond, lay one deck of river sand at the bottom of the pond, be provided with inlet and outlet pipes in the pond, water depth 40cm in the pond, have water hyacinth, apple snail etc. in water cultivation, in water body Cultivate some plankton in it.

[0012] The culture pond is 50 square meters, and the depth is between 80.

[0013] Described after late autumn, build plastic shed for culture pond. This can maintain the temperature of the culture and prevent the loach from being frozen to death during the winter. Due to the increase in temperature, the growth cycle of the loach can be extended by up to 4 months, which greatly improves the time for the loach to go to market.

[0014] The river sand is used in conjunction with coarse river sand and fine river sand, and the thickness of the laying is between 15. This can improve the living environment of the loach, reduce the...

Embodiment 2

[0018] A kind of loach soilless culture method, it is characterized in that: build culture pond, lay one deck of river sand at the bottom of the pond, be provided with inlet and discharge pipes in the pond, the depth of water in the pond is 50cm, cultivate water hyacinth, apple snail etc. in the water, in the water body Cultivate some plankton in it.

[0019] The culture pond is 60 square meters, and the depth is between 100cm.

[0020] Described after late autumn, build plastic shed for culture pond. This can maintain the temperature of the culture and prevent the loach from being frozen to death during the winter. Due to the increase in temperature, the growth cycle of the loach can be extended by up to 4 months, which greatly improves the time for the loach to go to market.

[0021] The river sand is used in conjunction with coarse river sand and fine river sand, and the thickness of the laying is between 20cm. This can improve the living environment of the lo...

Abstract

The invention discloses a soilless loach breeding method. A breeding pond is established, a layer of river sand is laid on the pond bottom, a water inlet and outlet pipeline is arranged in the pond, the depth of water in the pond ranges from 30 cm to 60 cm, water hyacinth, ampullariagigas and the like are planted in water, and some planktons are cultivated in water. The soilless loach breeding method has the advantages that loach inhabits in fine sand, the catching efficiency is high during selling, the taste of the loach is better than that of the loach bred in mud, the breeding density is larger than that the loach bred in the mud by four times, and the length of the large loach incubated in spring can reach 15-16 cm at the end of the year in the pond built through concrete.

Description

technical field [0001] The invention relates to a culture field, in particular to a soilless culture method for loach. Background technique [0002] Loach has a slender body with a slightly cylindrical front section. The rear side is flat, the abdomen is round, and the head is small. Mouth small, inferior, horseshoe-shaped. Eyes small, no undereye thorns. Must be 5 pairs. The scales are extremely small, round and buried under the skin. The back of the body and both sides are gray-black, and there are many small black spots on the whole body. There are also many black spots on the head and each fin. The spots on the dorsal and caudal fin membranes are arranged in rows, and there is an obvious black spot at the base of the caudal peduncle. It has good nutritional value. With the current breeding and breeding methods, the loach often has the disadvantages of slow growth, small individuals, and heavy meaty smell. Contents of the invention [0003] For the problems referr...
