Recycling method for culture tail water of Babylonia areolata

Abstract

The invention discloses a recycling method for culture tail water of Babylonia areolata. A sand falling tank and a sedimentation and filtration tank are arranged outside a culture pond, impurities in the culture tail water can be settled in the sand falling tank, and part of the settled culture tail water can be directly pumped back to the culture pond after being subjected to sand filtration; and the other part is purified by the sedimentation and filtration tank and filtered by a sand filter tank, and then is recycled and enters the culture pond, so that the culture tail water is recycled. When the recycling method for the culture tail water is adopted to treat the culture tail water, the occurrence rate of diseases of babylonia areolata is reduced to 6.15% from original 41.54%, the breeding survival rate of the babylonia areolata can be increased to 89.7% or above from original 30.2%, the culture risk can be reduced, pollution of the culture tail water to the sea area environment can be reduced, the novel healthy Babylonia areolata management and maintenance mode which is energy-saving, water-saving and emission-reducing is realized, and the healthy and sustainable development of the Babylonia areolata industry is promoted.

Description

technical field

[0001] The invention belongs to the field of aquaculture, and in particular relates to a method for recycling and utilizing tail water of aquaculture tail water of snails. Background technique

[0002] Fangban Dongfeng snail (Babylonia spp.) is referred to as Dongfeng snail, commonly known as Wang snail, flower snail, and phoenix snail. The meat is delicious, crisp and refreshing. It is a rare marine economic gastropod second only to abalone. It is very popular in domestic and foreign markets. The market is in short supply. In recent years, Dongfeng snail farming has the advantages of high value, low risk, less technical difficulty in daily feeding and management, and simple operation. The area and production of Dongfeng snail farming have continued to increase, and the related industries it has driven have greatly promoted the development of coastal fishing villages in Hainan. With economic development and social development, it has become a new breed of ma...

[0028] A kind of recovery and utilization method of the culture tail water of Fangban Dongfeng snail, comprises the following steps:

[0029] In the process of cultivating the square snail, put the snail seedlings at a reasonable stocking density in the breeding pond, regularly feed the bait, and carry out corresponding daily management; and set the drainage channel 2 outside the breeding pond 1, the described Lay grating on top of the drain. Set the sand-falling tank 3 at the end of the drainage channel, discharge the culture tail water of the falling-sand tank from the breeding pond, 30% of the water passes through the sand and gravel layer 31 at the bottom of the sand-falling tank, and the diameter of the sand and gravel is 0.3-0.8mm. After filtering, it is Directly pump back the sand filter 4, the water after the sand filter directly flows back to the culture pond; the rest of the water flows into the sedimentation filter 5, and after sedimentation and filtration, it is pu...

[0038] A method for cultivating square-spotted snails, comprising the following steps:

[0039] After the seawater in the sea area is filtered by the sand filter, it is discharged into the breeding pond for cultivating the snails. After the seedlings of the snails are put in, the bait is regularly fed according to the cultivation method of the snails, and the corresponding daily management is carried out. . The tail water produced in the breeding process is recycled by the method described above. In order to ensure the water quality of the seawater that enters the culture pond and sand drop pond, the water quality can be measured in advance. The excess tail water from the sedimentation filter tank, or the aquaculture water after the harvest of Fangban Dongfeng snails, can also be discharged into the sea area from the sedimentation filter tank after treatment. In order to avoid polluting the environment of the sea area, it is also necessary to increase the water quality measu...
