Problems solved by technology

[0002] Silver pomfret belongs to Perciformes, Pomfret suborder, Pomfretaceae, Pomfret genus, the meat is white, tender, less spines, rich in protein, fat, calcium, phosphorus, iron, sodium, potassium, vitamin A, vitamin B 1 , Vitamin B 2 , niacin and other nutrients, regular consumption can strengthen the body, prevent myocardial infarction, cerebral thrombosis and other adult diseases, so it is favored by farmers and consumers. To meet the needs of consumers, it is particularly important to carry out artificial breeding of silver pomfret, a high-quality resource, and restore its resources.

Embodiment 1

[0028] The preparation and application of a special microecological preparation for silver pomfret comprises the following steps:

[0029] (1) Separately culture Lactobacillus plantarum, saccharomyces, Halomonas denitrificans and Bacillus subtilis to obtain bacterial liquid, culture at 30°C for 26 hours; weigh 26g of Lactobacillus plantarum and yeast respectively according to the weight percentage of the bacterial liquid. bacteria 25g, Halomonas denitrificans 35g, Bacillus subtilis 14g and medical stone powder 432g, the mixture was dried, pulverized and sieved to prepare probiotics.

[0030] (2) The prepared microecological preparation is used for silver pomfret breeding, such as figure 1 As shown, the immune protection rate of silver pomfret was increased by 13.5%, and the content of nitrite nitrogen in the breeding water was obviously reduced.

Embodiment 2

[0032] The preparation and application of a special microecological preparation for silver pomfret comprises the following steps:

[0033] (1) Separately culture Lactobacillus plantarum, saccharomyces, Haeomonas denitrification and Bacillus subtilis to obtain bacterial liquid, culture at 30°C for 27 hours; weigh 28g of Lactobacillus plantarum, yeast bacteria 22g, Halomonas denitrificans 34g, Bacillus subtilis 16g and medical stone powder 456g, the mixture was dried, pulverized and sieved to prepare the probiotics.

[0034] (2) The prepared microecological preparation is used for silver pomfret breeding, such as figure 2 As shown, the immune protection rate of silver pomfret increased by 15.2%, and the content of nitrite nitrogen in the breeding water was obviously reduced.

Abstract

The invention relates to a microecological preparation special for silver pomfret and a preparing method and application. The microecological preparation special for the silver pomfret comprises, by weight, 25-30% of lactobacillus plantarum, 20-25% of saccharomycetes, 25-30% of denitrified marinomonas sp and 10-15% of bacillus subtilis. The preparing method for the microecological preparation special for the silver pomfret comprises the steps that a culture medium is sequentially inoculated with lactobacillus plantarum, denitrified marinomonas sp, saccharomycetes and bacillus subtilis strain culture solutions, the mixture is fermented, and obtained bacterium liquid is mixed with a carrier material to obtain the microecological preparation. The microecological preparation special for the silver pomfret is applied to silver pomfret aquatic water and fodder, and can obviously improve the water quality of the silver pomfret aquatic water, and the organism immunity of cultured fishes.

Description

technical field [0001] The invention belongs to the technical field of microecological preparations, in particular to a special microecological preparation for silver pomfret and its preparation method and application. Background technique [0002] Silver pomfret belongs to Perciformes, Pomfret suborder, Pomfretaceae, Pomfret genus, the meat is white, tender, less spines, rich in protein, fat, calcium, phosphorus, iron, sodium, potassium, vitamin A, vitamin B 1 , Vitamin B 2 , niacin and other nutrients, regular consumption can strengthen the body, prevent myocardial infarction, cerebral thrombosis and other adult diseases, so it is favored by farmers and consumers. To meet the needs of consumers, it is particularly important to carry out the artificial breeding of silver pomfret, a high-quality resource, and restore its resources. In recent years, scholars at home and abroad have carried out in-depth research on the artificial propagation, seed cultivation and cultivation...
