一种华东地区稻田养殖一龄性早熟母蟹的方法
By digging cross-shaped ditches in paddy fields to plant specific aquatic plants and releasing juvenile crabs, the problem of low yield of one-year-old early-maturing crabs in the rice-crab co-cultivation model in East China has been solved, realizing efficient large-sized one-year-old early-maturing crab farming and improving the overall benefits of rice and crabs.

AI Technical Summary
In East China, the rice-crab co-cultivation model makes it difficult to balance crab breeding and rice planting, resulting in low yields, inconsistent sizes, and low market value of one-year-old early-maturing crabs.
Dig a cross-shaped ditch in the middle of the paddy field, plant water hyacinth and/or giant water hyacinth, as well as Elodea and/or Hydrilla verticillata. After transplanting rice seedlings, release female juvenile crabs when the water temperature is suitable, feed them with crab farming feed, and harvest them after the early maturity rate reaches 70-90%. Combine paddy field management techniques to optimize water quality and feeding strategies.
This method has enabled high-yield and high-specification farming of large-sized, one-year-old early-maturing crabs in rice paddies, with yields exceeding 50 jin/mu and sizes exceeding 30g, thereby improving the overall profitability of rice cultivation and reducing feed costs.
