Embodiment Construction

[0024] In order for those skilled in the art to better understand the technical solutions provided by the present invention, the following will be described in conjunction with specific embodiments.

[0025] The method for effectively suppressing the propagation of vibrio in prawn culture provided by the embodiments of the present invention comprises the following steps:

[0026] (1) Clean up and disinfect, disinfect the breeding pond after finishing; expose the empty pond to the sun, and then use 25g / m of available chlorine in the water 3 The concentration is treated for more than 6 hours, aeration;

[0027] (2) Adjust the carbon-nitrogen ratio of the water body, aerate, and add 8g / m of carbon source every day 3 , Shrimp chips with a protein content of more than 45% 4g / m 3 , the DO in the water body is not less than 5~6g / m 3 ;

[0028] (3) After 4-5 days, when the transparency is 40-50cm, you can test the water and release the seedlings. After 24 hours, the survival rate ...

Abstract

The invention discloses a method for effectively inhibiting vibrio breeding in shrimp culture. According to the method, an organic carbon substance is artificially added, the carbon to nitrogen (C / N) ratio in a water body is adjusted, the amount of heterotrophic bacteria in a water environment is increased, microbes are used for assimilating inorganic nitrogen to convert culture metabolites such as ammonia nitrogen in the water body into self components of bacteria, the self components of bacteria are flocculated into particulate matters by the bacteria, and the particulate matters are ingested by cultured organisms, so that the effect of effectively inhibiting vibrio breeding in shrimp culture is achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, and specifically refers to a method for effectively inhibiting the reproduction of Vibrio in prawn cultivation. Background technique [0002] Vibrio (vibrio) is one of the common bacterial groups in the marine environment. This type of bacteria has strong adaptability and stress resistance, so it has become the dominant population in the seawater environment, especially Vibrio alginolyticus, Vibrio parahaemolyticus, Vibrio eel predominates. Currently, the ninth edition of "Bergey's Handbook of Bacteriology" includes 35 species of Vibrio bacteria. With the rapid development of artificial breeding and the ecological changes of the breeding waters, vibriosis has become one of the main bacterial diseases of marine animals. [0003] Vibriosis (Vibriosis), caused by bacteria of the genus Vibrio, is the most prevalent and harmful bacterial disease in aquatic animals such as fish, shrimp, crab, and shellfish...
