Problems solved by technology

Conventional feeding of rotifers has incomplete nutrients and low nutritional value, so special nutrient enhancement technology for rotifers is needed to strengthen microalgae nutrition, etc.
However, these substances are generally deposited on organic debris through the food chain, and cannot effectively participate in the material cycle.

Abstract

The invention is a water regulating disease preventing biological medium used for freshwater aquaculture animal fry culture. The water regulating disease preventing biological medium consists of fermented soybean meal, sugarcane molasses, wheat bran, lactic acid bacteria, saccharomycetes, monopotassium phosphate, monocalcium phosphate, magnesium sulfate and sodium chloride, wherein lactic acid bacteria are obtained by mixing lactobacillus plantarum with bacillus coagulans. By regular use of the biological medium disclosed by the invention, beneficial bacteria communities including ammonifyingbacteria, nitrite bacteria, nitrifying bacteria, denitrifying bacteria and the like can be gradually cultivated in a water body; the biological medium has stable and efficient ''denitriding'' ability,has both an assimilation function and a dissimilation function (making waste nitrogen in the water leave the water body in the form of nitrogen), purifies the water body and stabilizes the system. Inaddition, beneficial microorganisms including yeasts and the like can further be cultivated, and thus, transformation of substances of the water body is promoted, the biomass of zooplanktons in the water body is improved, the growth of bacteria and algae is balanced, feeding nutrition of fries is increased, and the occurrence of diseases is reduced.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a biological base for water diversion and disease prevention for the cultivation of freshwater cultured animal seedlings. Background technique [0002] In order to improve fry survival rate and fry quality, reducing environmental stress and nutritional stress are two effective ways. Usually, on the one hand, the water is thoroughly disinfected. After the larvae open their mouths to feed, in the process of raising seedlings, fresh algae fluids are directional cultivated by applying nitrogen fertilizers and other cultivation techniques to maintain the algae phase, effectively inhibit pathogens, and degrade sediments; Provide suitable and sufficient opening bait in time at each stage of the growth of larvae and juveniles, minimize the nutritional stress on the growth of larvae and juveniles, and ensure a large and stable supply of rotifers, cladocerans, and copepods....
