Can Microcystis spp. blooms be used in animal feeds?

A recent paper by Chen et al. published in Science of the Total Environment reviews the challenges of using blooms of Microcystis spp. in animal feeds.

Highlights (from the paper):

  • Microcystis causes toxicity to mollusks, crustaceans, fish, amphibians, mammals and birds.
  • Microcystis induces toxicity in liver, kidney, intestine, spleen and other organs.
  • Fish fed Microcystis may be not safe for consumption for humans.
  • Microbial pathogens may be present in cyanobacterial blooms.
