Embodiment Construction

[0027] An efficient ecological breeding method of Penaeus vannamei includes the following steps:

[0028] (1) Establish a breeding greenhouse

[0029] The breeding base adopts muddy ponds with high-density greenhouses and intensive cultivation methods. The ponds are slope-protected. Each pond has an area of ​​4-6 acres and a water depth of 1.0m-1.5m. The upper is a plastic greenhouse with a steel frame structure. Independent water inlet channels, independent and unobstructed water inlets for the growing ponds in the base; drainage adopts the method of setting up a bottom drainage system, and the entrance of the pond is equipped with aeration power of 2 kW / mu;

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

[0031] (1) Preparations before stocking shrimp larvae

[0032] ① Pond disinfection: use bleaching powder with effective chlorine ≥ 28% or sodium dichloroisocyanurate for pond disinfection; apply 15 kg of bleaching powder per acre, and splash the whole pond with ...

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

Technical field [0001] The invention relates to a method for breeding Penaeus vannamei. Background technique [0002] The existing South American giant white shrimp farming generally has defects such as low survival rate and long farming cycle, and needs further improvement. Summary of the invention [0003] The purpose of the present invention is to provide an efficient ecological breeding method of Penaeus vannamei with high survival rate and convenient operation. [0004] The technical solution of the present invention is: [0005] An efficient ecological breeding method of Penaeus vannamei is characterized in that it comprises the following steps: [0006] (1) Establish a breeding greenhouse [0007] The breeding base adopts muddy ponds with high-density greenhouses and intensive cultivation methods. The ponds are slope-protected. Each pond has an area of ​​4-6 acres and a water depth of 1.0m-1.5m. The upper is a plastic greenhouse with a steel frame structure. Independent water i...
