Problems solved by technology

In summer, the pond water temperature is high and lasts for a long time, and the surface water temperature of the ginseng pond can reach above 32°C, which has dealt a serious blow to the sea cucumber farming industry in the Yellow River Delta region and brought huge losses to the sea cucumber farming households

Embodiment Construction

[0021] A sea cucumber culture method in spring and summer, through the improvement of the following four aspects, avoids the risk of summer sea cucumber and greatly improves the safety of sea cucumber summer.

[0022] Specifically include the following steps:

[0023] 1. Regulation of ecological environment in aquaculture ponds:

[0024] (1) Combine reasonable water level adjustment and pull-net shading technology to adjust the light intensity, pond water temperature, and salinity of sea cucumber culture ponds; adjust the water level to about 1.0 meters in spring, use Bacillus to increase transparency, and the transparency is 50-70 cm , increase the depth of sunlight exposure and increase the water temperature. It is advisable to change the water at 10% of the total water body each time; when entering the water, it is best to choose to do it at noon or afternoon on a sunny day; before summer comes, raise the water level to about 1.6 meters. EM bacteria, reduce the transparenc...

Abstract

The invention discloses a sea cucumber spring and summer culture method. The sea cucumber spring and summer culture method aims at avoiding the aestivation risk of sea cucumbers and greatly improving the aestivation safety of the sea cucumbers through improvement of four aspects comprising eight steps. The four aspects comprise performing ecological environment regulation on a culture pond; adopting a relay type cultivation mode; constructing the step type pond; cultivating seedlings in batches. According to the sea cucumber spring and summer culture method, the related technology research is performed due to main restricting factors that the water temperature is high, the salinity is low, the water quality is poor, the oxygen deficiency of the bottom is easy to cause, and the like caused by the summer climate according to the area self-characteristics of the stichopus pond cultivation of the yellow river delta, the problem of the aestivation of the stichopus pond cultivation of the yellow river delta is majorly solved, the systematic technical support is provided for the aestivation of the sea cucumbers, and accordingly the healthy sustainable development of the stichopus pond cultivation industry of the yellow river delta is ensured.

Description

technical field [0001] The invention relates to the technical field of sea cucumber cultivation, in particular to a spring and summer cultivation method of sea cucumber. Background technique [0002] Due to the continuous high temperature and concentrated rainfall brought about by summer weather changes, the sea cucumber culture in tidal flat ponds in the Yellow River Delta area has suffered serious losses, especially the water temperature, low salinity, poor water quality, and harmful phytoplankton algae for the survival and growth of sea cucumbers in the aestivation state. The main restricting factors such as hair growth, through the cultivation and application of high-temperature resistant strains, combined with light intensity, water temperature, water quality, salinity and algal balance control technology, establish the technology of sea cucumbers in ponds in the Yellow River Delta to cope with high temperatures in summer to prevent frequent disease and death. In order ...
