Embodiment Construction

[0027] A kind of efficient ecological cultivation method of Penaeus vannamei comprises the following steps:

[0028] (1) Establish a breeding greenhouse

[0029] The breeding base adopts a muddy pond with a high-density greenhouse intensive cultivation method, and the pond is slope protected. The area of ​​each pond mouth is 4 to 6 mu, the water depth is 1.0m to 1.5m, and the upper part is a plastic greenhouse with a steel frame structure. Independent water inlet channels, independent and unimpeded water intake for each growing pond in the base; drainage adopts the method of setting up a bottom drainage system, and the pond mouth is equipped with an oxygen-increasing power of 2 kW / mu;

[0030] (2) Selection of seedlings and preparation before stocking

[0031] (1) Preparation before stocking shrimp seedlings

[0032] ① Pond disinfection: Use bleaching powder with available chlorine ≥ 28% or sodium dichloroisocyanurate for pond disinfection; apply 15 kilograms of bleaching po...

Abstract

The invention discloses a high-efficiency ecological breeding method for South American white shrimps. The high-efficiency ecological breeding method includes the steps such as breeding greenhouse building, offspring seed selection, stocking preparation, breeding management, water quality management. The technology is advanced and applicable; operability is strong; and breeding risk of South American white shrimps is reduced. Disease incidence is reduced. Dissolved oxygen of varied water layers in greenhouses is improved; condition of bottom layer water is improved; improvement in appetites of the South American white shrimps is benefited; and digestibility and utilization rate of feeds are increased.

Description
