Problems solved by technology
However, in industrial aquaculture, it is very difficult to stably control the algal phase and maintain good water color, and the existing technical means cannot achieve precise control under the condition of industrial circulating water. Therefore, it is urgent to reduce the losses caused by mutual cannibalism of prawns under the condition of high density of circulating water technical means

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] see Figure 1-Figure 2 , a three-dimensional culture system for regulating the water color of prawns in circulating water, including a container 2 for storing artificial pigment mixed liquid, and an aerator 7; the container 2 extends to the vicinity of the aerator 7 through a liquid inlet hose 6, and An automatic filling pump 3 is provided at the bottom, and the artificial pigment mixed liquid is evenly mixed with the pool water through the agitation of the aerator; a sampler is arranged in the culture pond 1, and the sampler is connected with the transparency sensor 4, and the transparency sensor 4 is connected with the control box 5; The control box 5 is also connected with the automatic filling pump 3; a nylon mesh 8 with a mesh size of 8-10 cm is laid at a certain depth under the water surface, and the nylon mesh 8 is laid with a lay...

The invention relates to a circulating water prawn water color regulation and control stereo culture system comprising a container that stores an artificial pigment mixed liquor and an aerator; the container extends to the aerator via a liquid inlet flexible pipe; an automatic liquid feeding pump is arranged in the front portion of the liquid inlet flexible pipe; the artificial pigment mixed liquor and the pond water are evenly mixed under the stirring effect of the aerator; a sampler in the culture pond is connected with a transparency sensor; the transparency sensor is connected with a control box; the control box is also connected with the automatic liquid feeding pump; a nylon net with the mesh of 8-10cm is arranged at certain depth under the water surface; a nylon net layer is repeatedly paved below said nylon net at a spacing A until the final layer is paved, wherein the distance between the final layer and the pond bottom is the spacing A or close to A. the water color regulation and control artificial automation control is realized so as to build a prawn shielding protection and comfortable culture environment, thus improving the prawn survival rate in an exuviation period,fully utilizing the culture water body space stereo culture, increasing the culture density, and effective minimizing prawn mutual devouring losses.
Description
technical field [0001] The invention relates to a prawn cultivation system, in particular to a three-dimensional cultivation system for prawns with water color control in circulating water, and belongs to the technical field of prawn cultivation. Background technique [0002] Under the conditions of industrialized recirculating aquaculture, existing technical means can satisfy the environment (such as temperature, dissolved oxygen, salinity, pH, ammonia nitrogen etc.) There are big problems, one of which is the loss of prawns due to molting and cannibalism. [0003] Good water color in the outdoor shrimp pond can provide shelter for the prawns and improve the survival rate of the prawns during the molting period. However, in industrial aquaculture, it is very difficult to stably control the algal phase and maintain good water color, and the existing technical means cannot achieve precise control under the condition of industrial circulating water. Therefore, it is urgent to...
