According to the Ohio Department of Natural Resource’s Ohio Field Guide to Aquatic Invasive Species, the Grass carp is a type of Asian Carp. They are a light green or “olive to silvery white,” and weigh from 65 to 80 pounds.

Control measures currently seem to rely on preventative measures. Other measures include tracking the fish in order to track them and rounding them up in order to electrocute them and fish them.

According to the ODNR, only sterile carp are allowed to be sold in Ohio. This is in an effort to prevent their spread.

Grass carp, if allowed to spread, can eat the food sources of native species. Their excrement can also “cause harmful algal blooms and affect water quality,” according to the ODNR’s Field Guide.
