An artificial substrate for Procambarus clarkii culture

Abstract

The invention belongs to the field of aquaculture, and relates to an artificial substrate for breeding procambarus clarkii. The artificial substrate is in an arc-shaped imbricate shape; four openings are formed in the side of the bottom side of the artificial substrate; the artificial substrate is made form ceramic material and is prepared by firing compound clay. According to the artificial substrate, the water body can be fully utilized, the spatial heterogeneity of the aquatic water is improved, and the inhabiting area of the procambarus clarkii is enlarged. Tourmaline powder is added into the artificial substrate in the manufacturing process, so that the pH value of the water is stabilized by the tourmaline, ammonia nitrogen is absorbed and degraded, water molecular groups are activated, self cleaning capacity of water is improved, and water change quantity and water pollution can be reduced. Furthermore, nutrient elements with a special proportion are added into the substrate, so that the artificial substrate is beneficial to the growth of alga such as diatom and the like which are good for ingestion and growth of the procambarus clarkii in the water.

Description

technical field [0001] The invention belongs to the field of aquaculture and relates to an artificial substrate for Procambarus clarkii cultivation. Background technique [0002] In recent years, as the consumption of Procambarus clarkii has become more and more accepted by the public, the consumption of Procambarus clarkii has increased sharply in the "Yangtze River Delta" region, and its breeding scale and scope have also continued to expand. It has formed regional characteristics that can effectively drive the development of aquaculture. Field investigation often finds that, due to its own territoriality in its physiological characteristics, in water bodies with high breeding density, Procambarus clarkii often affects feeding and reproduction due to domain fights on the pond base, and grows slowly and reproduces difficultly. At the same time, due to the high degree of eutrophication in aquaculture water, it is easy to grow and explode cyanobacteria blooms, but it is diff...

AI Technical Summary

Problems solved by technology

Stocking densities often fail to expand due to territorial physiology

[0005] (2) The bottom mud of the breeding pond is silted, often depositing a large amount of nutrient-rich substances and flocculated cyanobacterial debris, which is not suitable for the growth of beneficial algae bait such as benthic diatoms

[0006] (3) The water quality fluctuates frequently, and the PH value of the water body is more acidic, which affects the growth rate of Procambarus clarkii
