A kind of shrimp-crab pond ecological culture system and culture method thereof

Abstract

The invention relates to the technical field of aquaculture, and discloses a shrimp-crab pond ecological cultivation system and a cultivation method thereof, comprising a rectangular pond, the bottom of the pond is provided with several soil ridges parallel to the long sides of the pond, and the sides of the pond are There is an air supply pipe between the slope and the middle soil ridge and between two adjacent soil ridges, and several aeration tube rings with micropores are connected to the air supply pipe. Lay aquatic weed suppression film, insert several plastic pipes with small holes in the pipe wall vertically on the water weed suppression film to form soil caves, plant Elodea and bitter grass or water grass and bitter grass in turn in the soil caves, and cultivate Chinese cashmere in the pond Crayfish, Procambarus clarkii and Macrobrachium japonicus, or farming of Chinese mitten crabs, Procambarus clarkii and Penaeus vannamei. The invention realizes the cultivation of river crabs, crayfish, freshwater shrimps or vannamei in the same pond, which not only increases the pond cultivation output, but also improves the comprehensive breeding benefits.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a shrimp-crab pond ecological culture system and a culture method thereof. Background technique [0002] Procambarus clarkii is commonly known as crayfish, Macrobrachium japonica is commonly known as freshwater shrimp or river prawn, Chinese mitten crab is commonly known as river crab, hairy crab, hairy crab, and Penaeus vannamei is also known as Litopenaeus vannamei, all of which are aquaculture species with great economic value in my country. object. Among them, the output value of Procambarus clarkii and Chinese mitten crab aquaculture has exceeded 50 billion yuan, and the development momentum is good. However, the above-mentioned shrimp or crab farming has a low yield per mu. The average yield per mu of crayfish is only about 100 kg, and that of river crab is only about 75 kg. In recent years, with the vigorous promotion of farming in various places, the prices of river ...

Problems solved by technology

However, these models have exposed many problems in practical applications, such as hypoxia and a sharp rise in pH for a certain period of time caused by the overgrowth of aquatic plants covering too much water surface; Cause a large number of shrimp and crabs to die; or because the aquatic plants are excessively expanded and block the water flow, resulting in poor oxygenation effect at the bottom or the water surface; or because the aquatic plants cover too much, the bait thrown is stuck on the aquatic plants, and the shrimp and crabs cannot find food and are wasted ; or due to failure to grasp the growth characteristics of shrimp and crabs, their growth performance cannot be fully utilized, and the market can be realized as soon as possible to save breeding costs; The yield and benefit of the whole pond

In short, the common shrimp and crab polyculture model has not formed a stable and operable production process
