Penaeus vanmamei circulating integrated culture system and method

Abstract

The invention discloses a penaeus vanmamei circulating integrated culture system and method. The system comprises a biogas digester, a culture pond and a culture shed. The biogas digester is located underground. The culture pond is located on the biogas digester and arranged in the culture shed. The culture shed further comprises a heat supply device and an oxygen supply device. The culture pool and the biogas digester are built based on the prior art. The integrated circulating structure of the biogas digester and the culture pond is adopted for culturing penaeus vanmamei, the greenhouse type heat accumulation and preservation system design is adopted, fuel gas produced by the biogas digester is provided for the shed for keeping temperature constant, meanwhile, an appropriate temperature field can be produced in the biogas digester conveniently, the energy utilization cyclicity is improved, waste produced by culture is used for the biogas digester, and resources are reasonably utilized.

Description

technical field [0001] The invention belongs to the technical field of aquatic product cultivation, and in particular relates to a circulation integrated cultivation system of Penaeus vannamei and a cultivation method thereof. Background technique [0002] The living habits of prawns: (1) Water temperature: the suitable range is 17°C-35°C, and the optimum temperature is 25°C-32°C. If the temperature is lower than 16°C, stop feeding, lie on the side, and enter a state of suspended animation; if the temperature is lower than 12°C, a large number of tiger prawns will die; if the temperature is lower than 9°C, all of them will die. (2) Salinity: Widely saline. The suitable range is 0.2‰-45‰, and the most suitable range is 10‰. Penaeus vannamei can grow normally in fresh water (the pond bottom mud contains a small amount of salt), and the minimum salt content of Penaeus monodon is required to be above 4‰; (3) pH value: the suitable range is 7.5-9.0, and the optimum range is 7.8...

Problems solved by technology

(4) Dissolved oxygen (DO): more than 4mg / L is the best, can tolerate 1.2mg / L for a long time, but the growth is slow

[0003] In the current shrimp farming industry, the biggest problem lies in disease prevention and control and how to use appropriate models for farming. The water temperature for shrimp farming: the suitable range is 17°C-35°C, and the optimum temperature is 25°C-32°C. It is necessary to maintain the water temperature or the ambient temperature, which consumes a lot of energy, increases the cost of breeding, and indirectly pollutes the environment.
