Effect of EM and Chlorella vulgaris on the microbial communities in Eriocheir sinensis culture ponds with cyanobacterial blooms

Cyanobacterial blooms threatens the quality and safety of Chinese mitten crab Eriocheir sinensis, which is in great demand among a growing number of Chinese consumers. A combination of microalgae and probiotics seems a promising way to prevent and control cyanobacterial blooms in aquaculture ponds. In E. sinensis cultivation, however, related strategy is still lacking. Aiming to assess the potential combined effects of EM and C. vulgaris on regulating cyanobacterial blooms in E. sinensis culture pond, in the present study, we detected the alterations in water quality and microbial compositions of E. sinensis culture ponds with cyanobacterial blooms.

蓝藻水华（Cyanobacterial blooms）对市场需求日益增长的中华绒螯蟹（Eriocheir sinensis）的养殖品质与安全构成威胁。微藻与益生菌联合施用，被认为是水产养殖池塘中防控蓝藻水华的潜在有效手段。然而，在中华绒螯蟹的养殖体系中，此类防控策略仍较为匮乏。本研究旨在评估有效微生物（Effective Microorganisms, EM）与普通小球藻（Chlorella vulgaris, C. vulgaris）联合施用对中华绒螯蟹养殖池塘蓝藻水华的调控潜力，并对发生蓝藻水华的中华绒螯蟹养殖池塘的水质与微生物群落组成变化进行了检测。
