Method for culturing procambarus clarkia by reforming paddy field into pond

Abstract

The invention discloses a method for culturing a procambarus clarkia by reforming a paddy field into a pond. The method comprises the following technical steps: (1) reform of the paddy field; (2) construction of an escape-proof facility; (3) culture and propagation of a parent shrimp; (4) preparation of a pelletized feed; (5) formation of a larva; and (6) fishery. The method can be used for increasing the per-unit yield of the procambarus clarkia quickly and can also propagate a large quantity of young shrimps for personal culture and sale, thereby improving the culture yield and the culture benefit obviously.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and more specifically relates to a field-to-pond culture method for Procambarus clarkii. Background technique [0002] Procambarus clarkii is native to North America, commonly known as freshwater crayfish, and belongs to Arthropoda, Crustacea, Subclass Decapod, Cryridae. It was introduced to China in 1929 and has been widely distributed in my country. [0003] Due to the rapid growth of market consumption and export processing quantity of Procambarus clarkii, the number of its wild resources is decreasing sharply. Therefore, increasing the production of Procambarus clarkii through artificial breeding has become an important task to meet the processing, export and consumption markets. One of the ways, at present, the pond culture method of Crayfish clarkii usually comprises the preparation of pond before stocking in a suitable place, broodstock shrimp is stocked in a suitable place to breed, b...

Problems solved by technology

Its defects are: 1. The water quality is too fertile, which may easily cause the death of Procambarus clarkii due to lack of oxygen; 2. The ecological environment of the bottom surface of the pond is deteriorated by the pollution of organic fertilizers. In the shallow water area of ​​the pond slope, the result is that the cannibalism rate increases significantly, and the breeding output is difficult to increase; 3. The aquatic plants at the bottom of the pond can be used as feed for Procambarus clarkii, and at the same time, it can improve the ecological environment of the water body and serve as a When a large amount of organic fertilizer is dissolved in the water, the transparency of the water body will be greatly reduced, making it difficult for the aquatic plants at the bottom of the pond to survive due to the lack of light.

Procambarus clarkii cultured in ponds lacking aquatic plants not only grows slowly, but also has a high rate of self-colonization, and the ecological environment of the pond is easy to deteriorate; 4. After the water quality of the pond deteriorates, a large amount of water needs to be changed, and the energy consumption increases; 5. Livestock The manure is fermented at the bottom of the water and mainly plays the role of fertilizer and water. Not only is there a large amount of fertilizer waste, but also the water pollution caused will affect the artificial feed intake of Crayfish clarkii, and the feed utilization rate will decrease, which will eventually affect the cultivation of Crayfish clarkii The improvement of output, due to the existence of above-mentioned defect, causes the cost of existing Crayfish pond cultivation method to be on the high side, and output is lower and benefit is not ideal enough
