Embodiment 1

[0028] Digging to an area of ​​200m with a small excavator 2 , 5 earthen ponds with a height of 90cm. The bottom, ridge and inner wall of the ponds are compacted to make them smooth and tidy, and a high-density polyethylene impermeable film with a thickness of 0.35mm is laid. After drain pipes and overflow pipes are installed, fresh 50kg of snakehead sausage and 30kg of amaranth, and 30kg of apple snails. Each pool costs less than 5,000 yuan to build.

[0029] Add well water to a depth of 50 cm, and after 20 days, put in loach seedlings with a body length of 10-15 cm in the first ten days of May, and put in 200 kg of seedlings in each pond. Water spinach was put in at the beginning of June, and the planting area accounted for 1 / 3 of the loach breeding water surface, and the frame was made of moso bamboo to fix the water spinach. After July, water spinach is harvested every 40 days, and the density of each apple snail is controlled below 80kg, and the excess should be salvage...

Embodiment 2

[0032] Dig to an area of ​​50m with a small excavator 2, 5 earthen ponds with a height of 120cm. The bottom, ridge and inner wall of the ponds shall be compacted to make them smooth and tidy, and a high-density polyethylene anti-seepage film with a thickness of 0.25mm shall be laid. After drain pipes and overflow pipes are installed, fresh 20kg of snakehead sausage and 12kg of amaranth, and 10kg of apple snails. Each pool costs less than 1,400 yuan to build.

[0033] Add well water to a depth of 70 cm, and after 30 days, put in loach seedlings with a body length of 6 to 10 cm in the first ten days of April, and put in 40 kg of seedlings in each pond. Water spinach is put in at the beginning of May, and the planting area accounts for 2 / 5 of the loach breeding water surface, and the frame is made of moso bamboo to fix the water spinach. After June, water spinach is harvested every 30 days, and the density of each apple snail is controlled below 30kg, and the excess should be s...

Abstract

The invention belongs to the technical field of aquaculture, in particular relating to a new loach soilless culture method. The new loach soilless culture method comprises the following steps: building a culture pond, laying impermeable membranes on the wall of the pond and the bottom of the pond, arranging a drainage pipe in the pond, placing eclipta prostrate, acalypha australis linn and ampullaria gigas spix into the pond, and simultaneously putting water spinach or watercress into the pond; and after adding water and putting loach fries into the pond, then periodically harvesting the water spinach or the watercress, controlling the culture density of the ampullaria gigas spix and enhancing water quality management. By adopting the method, the defects in enclosure soil culture of a loach pond and the current soilless culture are overcome, and the method has the characteristics of easiness in regulation and control of water quality, feed conservation, few diseases and pests of loach, fast growth speed, capability of improving comprehensive benefits of the culture of the loach and the like.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a new soilless culture method for loach. Background technique [0002] Loach (Misgurnus anguillicaudatus) has high nutritional and medicinal value. It has a large demand in the domestic and foreign markets, and the price is relatively good. The artificial breeding has high profits and quick results, and the breeding prospect is promising. The breeding area of ​​loach in China is 15 million to 20 million square meters, mainly concentrated in Jiangsu, Henan, Hubei, Shandong, Anhui and Sichuan, and the breeding mode is mainly pond seine farming with soil. At present, the main factor that restricts the efficiency of loach farming is that the growth rate of loach is slow, and the annual growth rate is difficult to reach more than 3 times; the feed utilization rate is extremely low, and the bait coefficient is generally between 4.0 and 6.0, and some even as high as 8.0, which serio...
