Problems solved by technology

[0003] (1) Long breeding cycle: Compared with other marine cultured economic organisms, sea cucumber has the double dormancy characteristics of aestivation and hibernation, so the growth cycle itself is longer than that of other cultured organisms, and the current pond construction and breeding methods have not been carried out according to its characteristics. Therefore, it usually takes 30 to 36 months from hatching eggs to breeding commercial sea cucumbers
[0004] (2) High risk of breeding: the construction of japonicus breeding ponds in the prior art does not have the ability to prevent natural disaster risks such as high temperature, low temperature, and salinity drop, and there is no matching technology for disaster prevention. Since 2013, this The situation has already caused tens of billions of serious losses to the sea cucumber farming in our country
[0005] (3) Low breeding efficiency: Under the existing technical conditions, the survival rate of sea cucumber cultured in ponds is usually about 55-70% in the 12 months before reaching the commercial specification, and the growth rate is relatively slow
It can be seen that the current breeding ponds used for sea cucumber farming can no longer meet the needs of the sustainable and healthy development of the industry

Embodiment 1

[0041] Carry out present embodiment in Laiyang, Yantai: pond area is 50 mus.

[0042] (1) Pool bottom construction

[0043]Lay a layer of loess on the bottom of the pond and compact it. After compaction, the thickness of the loess layer is 20cm. After laying the loess, the effective water depth of the pond must reach 1.2m. The bottom of the pool is set up in the shape of "non". There are 2 vertical grooves and 23 horizontal grooves. Each groove is 2m wide and 10cm deep.

[0044] (2) Attachment base setting

[0045] At the bottom of the pond, two types of attachment bases are set longitudinally along the direction of the inlet and outlet, the breeding net cage and the wave-type sunshade net, and the ratio of the number of rows of the two attachment bases is 1:2. The diameter of the breeding net cage is 35cm, and the wave-type sunshade net is a double-layer green sunshade net supported by bamboo sticks or pvc pipes. After setting, the distance between the peak height and the b...

The diameter of the breeding net cage is 40cm, and the wave-type sunshade net is a double-layer green sunshade net supported by bamboo sticks or pvc pipes. The distance between the peak height and the bottom of the pon...

Embodiment 3

[0069] Carry out present embodiment in Penglai, Yantai: pond area is 20 mus.

[0070] (1) Pool bottom construction

[0071] Lay a layer of loess on the bottom of the pond and compact it. After compaction, the thickness of the loess layer is 40cm. After laying the loess, the effective water depth of the pond must reach 2.5m. The bottom of the pool is set in the shape of "non". There are 2 vertical grooves and 16 horizontal grooves. Each groove is 3m wide and 30cm deep.

[0072] (2) Attachment base setting

[0073] At the bottom of the pond, two kinds of attachment bases are set longitudinally along the direction of the inlet and outlet, the breeding net cage and the wave-type sunshade net, and the ratio of the number of rows of the two attachment bases is 2:1. The diameter of the breeding net cage is 45cm, and the wave-type sunshade net is a double-layer green sunshade net supported by bamboo sticks or pvc pipes. After setting, the distance between the peak height and the bot...

Abstract

The invention belongs to the technical field of stichopus japonicus aquaculture pond and application thereof. According to biological characteristics of stichopus japonicus, traditional pond bottom modification and selection and setup strategies of main foundation facilities including sediments, water inlet and outlet valves, interception filter screens and the like are broken through, and by redesign and optimization of the pond, the survival rate and the growth rate in stichopus japonicus aquaculture can be increased substantially, aquaculture loss risks caused by harmful organisms and extreme weather such as intensive heavy rainfall and continuous high temperature and low temperature, the stichopus japonicus annual aquaculture growth period can be prolonged by 0.8-1.2 months on the basis of high ecological safety of the environment, and remarkable quality and efficiency improvement effects are achieved. By aquaculture environment modification, aquaculture method adoption and suitable habitat construction, stichopus japonicus growth is promoted, and the annual aquaculture growth speed can be increased by 12-25%; in addition, aquaculture waste discharge and effects of aquaculturewaste on sediments can be reduced, and accordingly pond sediment ageing is retarded, and a pond cleaning period is prolonged substantially.

Description

technical field [0001] The invention belongs to the technical field of sea cucumber cultivation, and in particular relates to a sea cucumber cultivation pond and its application. Background technique [0002] Land-based pond farming is currently the main mode of sea cucumber farming in my country. Most of the ponds used were built during the shrimp farming boom in the 1970s or were newly built in recent years. Optimizing and transforming the academic characteristics. Especially in recent years, with the frequent occurrence of abnormal climate phenomena such as high temperature, freezing, and continuous rainfall, as well as the emergence of a series of new problems such as the degeneration of sea cucumber germplasm and the deterioration of the breeding environment, the benefits of sea cucumber farming have gradually declined. Some disadvantages of pond construction and breeding methods have become increasingly prominent, mainly in: [0003] (1) Long breeding cycle: Compared ...
