Abstract

The invention discloses a microecological preparation for improvement of an allogynogenetic crucian carp water body and a preparation method thereof. The preparation method comprises the following steps: (1) mixing mixed EM bacteria body fluid, sucrose, lactose, peptone and water according to a mass ratio of (5-10):(2-5):(1-5):(2-5):(80-90), transferring the mixture into a reaction bottle, and performing constant temperature fermentation at 37 DEG C for 3-5 days to obtain fermentation liquor; (2) drying and dehydrating bottom mud taken from an allogynogenetic crucian carp pond at 100-105 DEG C, crushing and sieving the bottom mud with a 40-100 mesh sieve to obtain a bottom mud powder material; (3) weighing copper oxalate and the bottom mud powder obtained in the step (2) according to a mass ratio of 1:(2-10), uniformly mixing the materials, adding water with the mass being 3-5 times the mass of the bottom mud powder, uniformly mixing the mixture, kneading the mixture into a spherical shape, drying the spherical mixture, calcining the mixture at 400-600 DEG C for 2-4 hours, and cooling the product to room temperature after the reaction; and (4) transferring the composite material obtained in the step (3) into the fermentation liquor obtained in the step (1), culturing for 5-10 days at room temperature, taking out the product, and air drying the product to obtain the microecological preparation. The microecological preparation provided by the invention can effectively improve the water quality of the allogynogenetic crucian carp water body, improve the immunity of allogynogenetic crucian carps, increase the survival rate of the allogynogenetic crucian carps, and promote the growth of the allogynogenetic crucian carps.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a micro-ecological preparation for water body improvement of heterogeneous gibel crucian carp and a preparation method thereof. Background technique [0002] The heterogeneous gibel carp is a hybrid of gibel carp with natural gynogenetic development in Fangzheng County, Heilongjiang as the female parent and Xingguo red carp as the male parent. It has the characteristics of rich nutrition, delicious meat, strong adaptability and fast growth. Farmed premium quality. In the process of its breeding, especially in the process of high-density breeding, it is necessary to manually feed a large amount of feed, and the residues of Russian feed and the excrement of aquatic animals are dissolved in the water, causing the indicators such as ammonia nitrogen, COD, and sulfide in the water quality to seriously exceed the standard, resulting in Aquaculture water pollution, which not only...
