工厂化循环水系统(RAS)养殖淡水鱼异味物质的产生及去除研究进展
Advances in the production and removal of off-flavors in Recirculating Aquaculture Systems(RAS)for the cultivation of freshwater fish
摘要
Abstract
Recirculating Aquaculture Systems(RAS),as an advanced aquaculture technology,achieve efficient utilization of water resources and a significant reduction in feed consumption through meticulous system manage-ment and the application of cutting-edge engineering techniques.Despite these advancements,the accumulation of metabolic waste generated during the cultivation process may trigger severe odor issues,posing a potential threat to the stability of the cultivation environment and production efficiency.This review comprehensively examines the mechanisms of odor generation in RAS systems and provides an in-depth analysis of the origins and influen-cing factors of two key odor-causing substances-geosmin(GSM)and 2-methylisoborneol(2-MIB).Furthermore,this paper systematically reviews the latest research progress in odor removal technologies within RAS systems,covering a variety of methods including biological,physical,and chemical treatments.By thoroughly comparing the advantages and disadvantages of these technologies in terms of efficiency,cost,ease of operation and environ-mental friendliness,this article aims to provide a theoretical basis and practical guidance for the further optimiza-tion and application of RAS technology,with the expectation of promoting the sustainable development of recircu-lating water aquaculture technology.关键词
