A kind of microbial water purifying agent for black fish culture water and preparation method thereof

Abstract

The invention discloses a microbial water purifying agent for snakehead culture water and a preparation method thereof. The preparation method comprises the following steps: adding 20-40 parts by weight of surface-modified C8 and C18 alkyl-chain magnetic silicon balls into 200-400 parts by weight of water; adding 80-100 parts by weight of microbial reagent, including 60-80 parts of Synechococcus, 60-80 parts of Oscillatoria, 10-30 parts of Nitrosococcus, 10-30 parts of Nitrosolobus, 10-20 parts of iron bacteria, 10-20 parts of Leptothrix, 1-5 parts of Thiothrix, 1-5 parts of Vitreoscilla, 30-70 parts of paramecium, 30-70 parts of infusorian, 30-50 parts of Tetraselmis and 30-50 parts of blue algae; and adding 50-90 parts by weight of beef extract peptone agar culture medium, and culturing. The microbial water purifying agent can be added into a snakehead culture tank to achieve the goal of purifying culture tank water.

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 used for snakehead aquaculture 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. Snakefish, also known as snakehead, snakehead, lizard, is ferocious in nature, strong in fecundity, and has a huge appetite. It can often eat all other fish in a certain lake or pond. As early as two thousand years ago, it was listed as the top grade of insects and fish by "Shen Nong's Materia Medica", stone honey, bee cock, beeswax (propolis), oyster, tortoise shell, mulberry octopus, sea clam, Meretrix meretrix, and carp. Black fish is a "dis...

Problems solved by technology

However, in the process of artificial breeding, because the density of breeding far exceeds the level of nature, the water body cannot process the excess bait and the excrement of snakeheaded fish, causing the water body to be polluted, the dissolved oxygen to drop, and the ammonia nitrogen index to rise, which is harmful to snakeheaded fish. Adverse effects on growth, which in turn affect farming efficiency

[0004] 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 snakeheaded fish, 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 snakehead's unsuitable symptoms
