Freshwater shrimp ecological pond culture system and method

Abstract

The invention discloses a freshwater shrimp ecological pond culture system. The system comprises a freshwater shrimp culture pond, an aquatic economic plant planting region and a silver carp and bighead carp culture pond, which are arranged in sequence and are communicated with each other, wherein an artificial shrimp nest is arranged in the freshwater shrimp culture pond and is used for stocking freshwater shrimps; houttuynia cordata and water spinaches are planted in the aquatic economic plant planting region; the silver carp and bighead carp culture pond are used for stocking silver carps and bighead carps; pond water circulates among the freshwater shrimp culture pond, the silver carp and bighead carp culture pond, the aquatic economic plant planting region and the freshwater shrimp culture pond. The system has the beneficial effects that the stocking density is improved by arranging the artificial shrimp nest; the freshwater shrimp culture pond water after culture provides baits for the silver carps and the bighead carps and provides nutrients for aquatic economic plants, thus the water is purified and flows into the freshwater shrimp culture pond again; under the condition of the same culture area, the freshwater shrimp yield is increased by 3-4 times and the yields of the silver carps and the bighead carps and the aquatic economic plants are substantially increased, and the drug dose is greatly reduced or even drugs are not used, thus achieving efficient ecological culture of freshwater shrimps.

Description

technical field [0001] The invention belongs to the technical field of pond cultivation, and in particular relates to a green shrimp pond ecological cultivation system capable of realizing high-efficiency ecological cultivation by setting artificial shrimp nests in combination with filter-feeding fish cultivation ponds and shrimp pond water circulation treatment in aquatic economic crop areas and ecological breeding methods. Background technique [0002] At present, cultured freshwater shrimp generally adopts artificial ponds to plant aquatic plants, and sometimes adopts a feeding method of filter-feeding silver carp and bighead carp. Due to the relatively strong seasonality of aquatic plants, it is easy to age and affect water quality in a short period of time. If no aquatic plants are planted, freshwater shrimp will directly contact the bottom mud, and the raised shrimp will turn black and be susceptible to pathogens. If the amount of silver carp and bighead carp raised i...

AI Technical Summary

Problems solved by technology

If the amount of silver carp and bighead carp raised in nests is small, the water purification effect will not be achieved. If the amount is large, their mobility will destroy the quiet environment necessary for the growth of freshwater shrimp, which will affect the growth and survival.

Therefore, it is difficult to increase the yield in freshwater shrimp farming
