Description

Technical Field

[0001] The invention relates to the technical field of shrimp fry breeding, and in particular to a feces recycling device for high-density shrimp fry breeding. Background Art

[0002] Shrimp fry farming is an important branch of aquaculture, which involves the hatching, cultivation and eventual sale of shrimp fry. Shrimp fry farming is a technology-intensive process that requires farmers to have certain professional knowledge and experience. With the development of aquaculture technology, shrimp fry farming is also constantly introducing new technologies, such as automated monitoring systems, precision feeding technology, etc., to improve farming efficiency and sustainability. The success or failure of shrimp fry farming directly affects the benefits of the entire farming process. The following are some key points of shrimp fry farming:

[0003] Hatching conditions: It is necessary to control appropriate environmental factors such as water temperature, salinity, pH value and dissolved oxygen to ensure the smooth hatching of shrimp fry.

[0004] Feed management: Provide sufficient high-quality feed to ensure that the shrimp fry obtain the necessary nutrition and promote their healthy growth.

[0005] Water quality control: Regularly test and adjust water quality to prevent the accumulation of harmful substances such as ammonia nitrogen and nitrite.

[0006] However, shrimp fry farming is a systematic project. In the farming equipment, impurities in the farming water need to be cleaned regularly. If the feces are not cleaned in time, it will affect the oxygen content of the water and cause an increase in shrimp fry microorganisms, thereby causing problems such as reduced farming production. For this reason, we propose a feces recycling device for high-density shrimp fry farming. Summary of the invention
