Histopathological alterations in triangle sail mussel (Hyriopsis cumingii) exposed to toxic cyanobacteria (Microcystis aeruginosa) under hypoxia

Hyriopsis cumingii has been considered as an aquaculture species for pearl production in China. In recent years, the mussels have been often suffered from hypoxia and toxic algae, but the effects of Microcystis aeruginosa associated with hypoxia on the morphological changes of selected organs such as gill, digestive gland and stomach are unclear. This study just clarified that the selected tissues of H. cumingii were more severely affected by the both stressors, which may clarify how the toxic algae and hypoxia cause some diseases in the mussel H. cumingii.
