Problems solved by technology

Reservoir flowing water farming method not only wastes water resources seriously, but also pollutes the surrounding environment due to untreated aquaculture sewage
Moreover, most reservoirs are distributed in mountainous areas, making long-distance transportation difficult
Indoor factory hybrid sturgeon breeding mainly relies on microbial nitrification and denitrification to remove nitrogen in the cultured water. This method has a better control effect on ammonia nitrogen produced during the breeding process, but it is prone to accumulation of phosphorus, potassium and many heavy metal ions

Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0017] Such as figure 1 As shown, a hybrid sturgeon culture system includes a culture pond 1 and a subsurface wetland pond 2, wherein the culture pond 1 can be single or multiple, and the total area ratio between the culture pond 1 and the subsurface wetland pond 2 is 5:1 to Between 7:1.

[0018] Such as figure 2 As shown, the subsurface wetland pool 2 is sequentially divided into a wetland water inlet area 21, a plant planting area 22, and a wetland water outlet area 23 by the grid 3; the plant planting area 22 is filled with a matrix, and the matrix almost fills the plant planting area 22, Close to the upper edge of the subsurface wetland pool 2, plants are planted above the substrate; a sewage pipe 7 is connected between the wetland water inlet area 21 and one end of the culture pond 1, and the sewage pipe 7 communicates with the middle part ...

Abstract

The invention relates to a culture system for hybridized sturgeons and belongs to the field of aquaculture. The culture system for the hybridized sturgeons comprises culture ponds and an underflow wetland pond, wherein the underflow wetland pond is sequentially divided into a wetland water inlet area, a plant planting area and a wetland water outlet area by grilles, a filtering device is arranged above a water surface of the wetland water inlet area, dirt pumps are separately arranged at the bottoms, close to the grilles, of the wetland water inlet area and the wetland water outlet area and all communicate with the filtering device through water pipes, a blow-off pipeline is connected between the wetland water inlet area and one end of each culture pond, a purified water pipeline is connected between the wetland water outlet area and the other end of each culture pond, and one end part, located in the wetland water outlet area, of the purified water pipeline is connected with a water pump. According to the culture system for the hybridized sturgeons, solid-liquid separation is achieved by using mechanical facilities, and metabolic wastes such as soluble nitrogen, phosphorus, potassium and heavy metals produced during the culture of the hybridized sturgeons are removed by using underflow wetland so as to achieve the cyclic utilization of water resources; and the culture system is located in a greenhouse, so that culture activities of the hybridized sturgeons can be carried out all the year round.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a hybrid sturgeon breeding system. Background technique [0002] The hybrid sturgeon is a species of fish produced by the crossbreeding of a sturgeon and a sturgeon. It has the advantages of fast growth, high feed conversion rate, strong disease resistance, high nutritional value, no thorns in muscles, and low temperature resistance. Because hybrid sturgeon breeding requires fresh water quality, dissolved oxygen above 6mg / L, pH of 7-8.5, high hardness, and preferably micro-flow environment, it is difficult to carry out breeding activities in ordinary ponds. Now, most of the hybrid sturgeon breeding industry is only limited to reservoir running water fish farming and indoor factory farming. Reservoir flowing water farming method not only seriously wastes water resources, but also pollutes the surrounding environment due to untreated aquaculture sewage. Moreover, most reservoirs are d...
