A kind of microbial water purifying agent for Chinese soft-shelled turtle breeding water and preparation method thereof

Abstract

The invention discloses a microbial water clarifying agent for Chinese softshell turtle cultivation water and a preparation method thereof. The preparation method comprises the following steps: adding 20-40 parts by weight of magnetic silica spheres with C8 and C18 alkyl chain-modified surfaces into 200-400 parts by weight of water; adding 80-100 parts by weight of microbial reagents, wherein the microbial reagents comprise the following raw materials: 50-70 parts of rhodopseudomonas palustris, 50-70 parts of oscillatoria cyanobacteria, 10-30 parts of nitrosospira, 10-30 parts of nitrosolobus, 10-20 parts of thiobacillus dentrificans, 10-20 parts of leptothrix, 1-3 parts of thiothrix, 1-3 parts of beggiatoaceae, 30-70 parts of paramecium, 30-70 parts of ciliate, 20-40 parts of platymonas subcordiformis and 20-40 parts of blue algae; and then adding 40-60 parts of by weight of beef extract peptone agar medium for culturing. The microbial water clarifying agent can achieve the purpose of purifying the cultivation water after being added into a Chinese softshell turtle culture pond.

Description

technical field [0001] The invention relates to a microbial water purifying agent and a preparation method thereof, in particular to a microbial water purifying agent for Chinese soft-shelled turtle breeding water and a preparation method thereof. Background technique [0002] In recent years, the rapid advancement of high-efficiency agriculture has led to the rapid development of special aquaculture. Famous, special and high-quality new aquaculture species have reached the level of large-scale production and formed their own characteristics. Chinese soft-shelled turtle is a high-protein (15-17%), low-fat (1-4%) aquatic product containing multiple vitamins and trace elements. It has high edible and medicinal value and high economic value. Chinese soft-shelled turtle mainly eats animal food. Under artificial breeding conditions, the body weight can reach about 400-500g after 12-15 months. Feed nutrition: protein accounts for 40-50% (animal protein accounts for more than 80%...

AI Technical Summary

Problems solved by technology

However, in the process of artificial breeding, because the breeding density far exceeds the natural level, the water body cannot handle the excess bait and the excrement of the Chinese soft-shelled turtle, causing the water body to be polluted, the dissolved oxygen to drop, and the ammonia nitrogen index to rise. The growth of soft-shelled turtles is adversely affected

[0003] In the current aquaculture technology, because the aquaculture water cannot be treated, it is easy to cause problems such as an increase in the incidence of soft-shelled turtles, a decrease in survival rate, and a decrease in production.

The conventional solution is to change the water at intervals, but on the one hand, changing the water will increase the production cost, and on the other hand, it will easily cause the unsuitable symptoms of the soft-shelled soft-shelled turtle.
