Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to an ecologically simulated energy-saving Procambarus clarkii shrimp seedling cultivation device and a cultivation method. Background Art

[0002] Procambarus clarkii is an omnivorous shrimp. Water quality and bait are important factors affecting the growth of Procambarus clarkii. In aquaculture, probiotics such as Bacillus, photosynthetic bacteria, and lactic acid bacteria are often used as water quality improvers, and fresh-frozen fish, corn, rapeseed cake, etc. are fed to Procambarus clarkii for food. In recent years, Procambarus clarkii has been mainly consumed in East China, South China, Central China, and North China, and has shown a trend of expanding to the Southwest, Northwest, and Northeast regions. The international demand for crayfish is also on the rise.

[0003] In the existing technology, the cultivation of Procambarus clarkii fry mostly uses cages or frames, and the breeding area is small, which cannot achieve the effect of ecological cultivation of Procambarus clarkii. Moreover, since the shrimp fry grow together in the same pond, their body lengths are different, and their feed intake is also different, which leads to a certain impact on the production speed of the shrimp fry. At the same time, the existing shrimp fry cultivation equipment is mostly built outdoors, and the growth of the shrimp fry is easily affected by external environmental factors, making it difficult to achieve large-scale cultivation. Summary of the Invention
