Embodiment 3

[0025] Shanghai Heqing Liujia Fry Farm has an area of ​​15 mu. The aquatic biological feed prepared in the first ten days of February 2006 was applied in the first ten days of February, 2006. As a result, the fish fry can be sold in late March. Compared with other nursery farmers, fry are sold about 12 days earlier, and the survival rate of fry has increased by 15% compared with previous years.

Abstract

The present invention discloses a kind of aquaculture biological feed. It is characterized by that it uses beneficial microbion as main active component, and said biological feed mainly contains bacillus subtitis, marsh rhodopseudomonad, torula yeast and acidophilic lactobacillus. Besides, said invention also provides its preparation method and concrete operation steps.

Description

technical field [0001] The present invention relates to a biological feed, in particular to an aquatic biological feed; in addition, the present invention also relates to a preparation method of the aquatic biological feed, to be precise, it is a secondary fermentation method of separately inoculating dual beneficial microorganisms. Background technique [0002] Excessive antibiotics and heavy metals have become two urgent problems facing the aquaculture industry. Abuse and excessive use of antibiotics leading to excessive content in the body has become one of the focuses of food safety. In addition, the food safety hazards caused by the heavy metals and other harmful substances carried by environmental pollution, which are transferred to the human body through the food chain, are also closely watched by people. [0003] In order to create a nutrient-rich water environment for the growth of fish and shrimp, the application of biological feed is undoubtedly the most direct a...
