Animal Fish Family: Cyprinidae Classification: Regulated
carp, which have been genetically altered to make them sterile, may be introduced
(with a permit from WDFW) to control aquatic weeds. There are guidelines
for introducing them. As mentioned before, the fish will uproot and eat most
aquatic vegetation, and do not preferentially target nuisance species such
as milfoil. They are a long-lived fish that gets quite large.
