Problems solved by technology

However, the current paddy farming methods and models are improper, and the crayfish produced are generally small in size, poor in color and have many diseases, which affects the survival rate and yield of crayfish, and cannot guarantee farmers to obtain corresponding economic benefits.
In addition, because the crayfish cultured in rice fields are fed with artificially compounded feed, the taste and nutrition of the crayfish produced are poor, and the nutrition of the natural crayfish cannot be achieved.

Embodiment 1

[0033] A method for cultivating crayfish in a rice field is characterized in that it comprises the following steps:

[0034] 1) paddy field preparation, specifically including the following steps:

[0035] a. Choose paddy fields with sufficient water sources, convenient drainage and irrigation, strong water retention capacity, no dry weather, no flooding, good ecological environment, no pollution sources around, fertile soil, and natural bottom structure;

[0036] b. Excavate a ring-shaped shrimp breeding ditch along the inside of the paddy field ridge, with a width of 3 meters and a depth of 2 meters. The ditch is 1 meter wide and 0.8 meters deep. The area of ​​circular ditch and field ditch accounts for 8% of the paddy field area;

[0037] c. Use the soil dug to widen, heighten and reinforce the surrounding field ridges to prevent water seepage or collapse. The top surface of the ridge is 2-3 meters wide and 1 meter higher than the field surface. The water level should be ...

Abstract

The invention belongs to the technical field of aquaculture and discloses a paddy field cultivation method for crayfish. The paddy field cultivation method is characterized by comprising the following steps of (1) paddy field preparation; (2) crayfish stocking; (3) feeding; and (4) breeding management, including the processes of (a) water quality control, (b) disease control, (c) overwintering management, and (d) catching of finished crayfish. The paddy field cultivation method for crayfish is aided by natural baits, such as hydrilla verticillata and living snails as foods for the crayfish, so that the breeding survival rate, nutrients and taste of the crayfish are improved; cyclic utilization of paddy field substances is achieved by adopting the natural bait of a paddy field ecosystem; and the breeding cost is also reduced.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating crayfish in paddy fields. Background technique [0002] The scientific name of freshwater crayfish is Procambarus clarkii, referred to as (small) lobster, which is a species of freshwater crayfish. Crayfish are native to the southern United States and northern Mexico. In the early 1930s, people transplanted them from the United States to Honshu, Japan as bullfrog bait, and then introduced them to China from Japan in the late 1930s. They grew and reproduced in areas near Nanjing and Chuxian. Later, it spread naturally along the Yangtze River Basin. From the 1980s to the 1990s, people introduced it to other places as a breeding object, and it is now distributed in more than a dozen provinces and cities in my country, and has become the dominant species in some lakes and ditches in some places. Crayfish meat is delicious, with unique flav...
