Table 4

The aggregation of erythrocytes within hepatic blood vessels (AHBVs), congestion of erythrocytes (CE), dilation of sinusoids (DSSs), revealing cytoplasmic vacuolation (CV), and necrosis (N) of fingerling grass carp (Ctenopharyngodon idella) 96 h after exposure to different levels of neonicotinoid (acetamiprid 20% SP).
