A Rice Field-Penaeus vannamei Heterotopic Ecological Breeding System

Abstract

The invention discloses an ectopic paddy field-penaeus monodon ecological breeding system which sequentially comprises a water purification unit, a primary purification paddy field, a secondary purification paddy field, a plurality of high-position shrimp breeding tanks and / or water storage tanks and a plurality of penaeus monodon greenhouses according to a water flow direction. A water inlet ditch is arranged on one side of each penaeus monodon greenhouse and communicated with the corresponding high-position shrimp breeding tank and / or water storage tank, and a drainage ditch is arranged on the other side of each penaeus monodon greenhouse and communicated with the primary purification paddy field. The organic paddy fields are separated from the high-position shrimp breeding tanks and thepenaeus monodon greenhouses, an ectopic paddy field-penaeus monodon ecological breeding mode is established, the problem of high death rate of intensive breeding of penaeus monodons is solved, penaeus monodon production and quality are improved, and both production and income are increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a paddy field-Penaeus vannamei ectopic ecological culture system. Background technique [0002] Penaeus vannamei, collectively referred to as Penaeus vannamei in my country, and its commercial name is Jiwei shrimp. Penaeus vannamei is a euryalline and tropical shrimp species. It has a thin shell and fat body, fresh and tender meat, high meat yield (65%), and disease resistance. Strong, fast growth, rich in nutrition and other advantages, native to the waters of the Pacific coast of the Americas, is recognized as one of the three largest shrimp species in the world today with the highest yield of farmed shrimp, introduced in my country in 1988, mainly in the wide salty coastal areas Aquaculture. The culture of Penaeus vannamei has developed from coastal areas to inland areas, and the farming models are also diversified. Winter shed farming in coastal areas, inland p...

Problems solved by technology

In the prior art, the culture mode coupled with the shrimp culture system and the rice planting system is mainly adopted, which not only stabilizes food production, but also provides a good water source for the growth of Penaeus vannamei through the rice fields. There have also been reports about the cultivation of prawns in the rice fields in recent years, and the relevant rice fields and ectopic culture of shrimp intensive culture (small shed culture) system has not been reported
