Safe summer-spending method for stichopus japonicus pond culture

Abstract

The invention provides a safe summer-spending method for stichopus japonicus pond culture. The technical scheme includes the steps of firstly, mounting underground well water cooling facilities; secondly, mounting pond shading nets; thirdly, arranging young stichopus japonicus protecting net cages. The safe summer-spending method for stichopus japonicus pond culture has the advantages that since the shading nets are mounted in a stichopus japonicus pond, the temperature increase speed and range of a water body can be decreased remarkably in high-temperature weather in summer and can be particularly decreased remarkably when the air temperature at noon; an underground well water circulating temperature decrease mode similar to an air conditioner is notable in temperature decrease effect and is capable of decreasing the water temperature effectively particularly in continuous high-temperature weather; the underground well water temperature is small in change range yearly, and a stichopus japonicus growth period can be delayed and a stichopus japonicus hibernation period can be shortened with the aid of underground well water temperature increase when the water temperature is low in both winter and spring, so that stichopus japonicus culture economic benefit can be further enhanced; with the help of the shading nets and underground water temperature decrease, the cost of adopting the net cages for protecting the young stichopus japonicus is little increased, the yield and specifications of the young stichopus japonicus are increased, and risks caused by the high-temperature weather are reduced effectively.

Description

technical field [0001] The invention relates to the technical field of pond cultivation, in particular to a method for safely spending the summer in pond cultivation of sea cucumbers. Background technique [0002] Sea cucumber is an important sea cucumber economic species in northern my country. As the market demand for sea cucumber continues to increase, the cultivation area and area of ​​sea cucumber continue to expand, especially the breakthrough of "east ginseng and west cultivation". The scale of ginseng farming has also continued to develop, and the area of ​​ginseng ponds in this area has reached 400,000 mu. The suitable growth temperature of sea cucumber is 15-23°C. When the water temperature is continuously higher than 24°C, the sea cucumber will stop feeding and moving, and enter into aestivation. At this time, the emergency disease resistance of sea cucumber is weakened. If the external environment is unfavorable, Apostichopus will be affected and appear skin rot ...

Problems solved by technology

The death of japonicus caused by high temperature in summer has always been a big problem in the development of japonicus aquaculture industry in the Yellow River Delta region. The traditional sea cucumber pond culture mode is mostly adopted in the Yellow River Delta area. The conditions of the culture facilities are relatively backward and have not been adjusted according to the climatic conditions. This pond mode cannot provide suitable and stable ecology for sea cucumbers in high temperature weather in summer. environment, it is urgent to find a way to reduce the losses caused by the high temperature in summer to the cultivation of japonicus in ponds
