“…Aquatic vegetation and algae are the primary producers of aquatic environment, keeping balance and stability of water ecological system, and directly or indirectly adjusting the structure and function of aquatic ecosystems (Ricardo, Virgile, & René, 2013;Zhang et al, 2016). Chlorella vulgaris, as a beneficial algae strain with abundant nutrients which can be used by omnivorous or herbivorous animals in aquaculture, was frequently chosen as the toxicity test materials (Geiger, Hornek-Gausterer, & Saçan, 2016;Najafabadi, Malekzadeh, Jalilian, Vossoughi, & Pazuki, 2015).
