Field
|
As a trophic competitor and a predator, Perccottus glenii has been implicated in the population declines of historically abundant native species such as Umbra krameri, Carassius carassius, and Leucapspius delineatus

Anecdotal
|
N/A
|
Perccottus glenii has led to unfavorable feeding relationships between other organisms, slower growth of native species, and prolonged spawning. P. glenii has been suggested to displace native species after invasion into small water bodies.
