Litopenaeus vannamei growth promoting microecologics and use method and application thereof

Abstract

The invention discloses a litopenaeus vannamei growth promoting microecologics and a use method and application thereof. The microecologics contains at least one or a combination of photosynthetic bacteria, lactic acid bacteria, rhodotorula benthica, corynebacterium glutamicum, clostridium butyricum, bacillus subtilis, bacillus licheniformis, bacillus coagulans, neutral protease, starch, cane sugar, magnesium sulfate and manganese sulfate. The aquatic product growth promoting preparation containing the micro-ecological microbial inoculum can promote the growth of litopenaeus vannamei, improvethe immunity of litopenaeus vannamei and adjust the micro-ecological balance of intestinal tracts of litopenaeus vannamei, can play a good role in purifying water in a water environment, and has a good application prospect in aquaculture.

Description

technical field [0001] The invention belongs to the field of micro-ecological preparations, and in particular relates to a growth-promoting micro-ecological preparation of Litopenaeus vannamei and its use method and application. Background technique [0002] Litopenaeus vannamei, also known as Penaeus vannamei, has a wide temperature range (6-39°C), strong salinity adaptability (0.5-50‰), fast growth, strong disease resistance, and delicious meat, etc. It has become one of the three major shrimp farming species in China and in the world. [0003] However, with the continuous expansion of the scale of the shrimp farming industry, the impact of diseases and environmental deterioration on its production has become increasingly significant. Such as White Spot Syndrome (WSD), Acute Hepatopancreatic Necrosis (AHPND), Viral Stealing Disease (VCMD), Yellow Head Disease (YHD), Infectious Myonecrosis (IMN), Taura Syndrome (TS), Enterosporidiosis (EHP) and infectious hypodermic and h...

Problems solved by technology

But in the pursuit of economic benefits, the breeding density is increasing, and the accumulation of residual bait and feces in the breeding water is becoming more and more serious. These organic matters are decomposed under the action of microorganisms to produce a large amount of ammonia nitrogen, nitrite and hydrogen sulfide. Substances that cause stress or toxicity to Litopenaeus shrimp, resulting in the decline of shrimp body function, germplasm degradation, and serious disease. A large number of antibiotics and other chemical drugs are used in its disease prevention and treatment

If things go on like this, bacteria have developed resistance to antibiotics, and the treatment effect is greatly reduced. In order to prevent the occurrence of diseases in a timely and effective manner, the dosage has to be increased, which increases the cost of breeding and forms a vicious circle.

[0004] At the same time, the use of antibiotics in aquaculture, the drug residues and the large amount of aquaculture wastewater discharge will also cause great harm to the surrounding ecological environment and human health, causing other problems such as ecological environment and food safety.
