MRNA RESPONSE-BASED VARIABLE FLOW CONTROL METHOD AND SYSTEM FOR RECIRCULATING AQUACULTURE SYSTEM

摘要

Disclosed are an mRNA response-based variable flow control method and system of a recirculating aquaculture system, so as to achieve coordinated regulation of a biofilter of a recirculating aquaculture system and a microorganism response. The mRNA real-time expression quantity of functional microbial ammonia oxidizing bacteria (AOB) is obtained, so that the flow speed of the system is increased in an mRNA response high expression time period of the AOB, and the flow speed of the system is reduced in a response low expression time period. The problems are solved that an existing aquaculture water treatment biofilter is low in treatment efficiency and high in running energy consumption from the perspectives of coordinated regulation of the industrial aquaculture water treatment technology and a microorganism response.
