Abstract: Cyanobacteria blooms in freshwater aquaculture ponds frequently occur due to the eutrophication, leading to serious problems in ecological environment and aquatic product quality safety.Toxins produced by cyanobacteria causes the most serious and direct harm to aquaculture animals.Microcystins(MCs)are a kind of cyanotoxins with the widest distribution, the highest frequency and the most serious harm.This paper reviews the characteristics of MCs including the spatial and temporal distribution in aquaculture ponds, accumulation toxic effect and action mechanism in aquacultured animals, research progress in the scientific prevention and control technology of MCs.To provide reference for reducing the harm of cyanobacteria blooms to freshwater aquaculture, suggestions were provided on the problems existing in the research and application field of scientific prevention and control of MCs in aquaculture ponds as well as the future development direction, including building ecological stereo culture model with multi-trophic level in freshwater pond, establishing tail water(circulating water)processing mode with the function of absorbing nitrogen and phosphorus and degrading MCs in freshwater aquaculture ponds, using MCs efficient degradation bacteria or efficient degradation enzyme to strengthen the emergency treatment of MCs harm, and developing targeted drugs based on the molecular mechanism involved in MCs toxicity.
