Coregonus artedi, commonly known as the cisco, is a North American species of freshwater whitefish in the family Salmonidae. The number of species and definition of species limits in North American ciscoes is a matter of debate. Accordingly, Coregonus artedi may refer either narrowly (sensu stricto) to one of the several types of cisco found e.g. in the Great Lakes, or broadly (sensu lato) to the complex of all ciscoes in continental North American lakes, Coregonus artedi sensu lato.

Is it venomous or poisonous?

We have no record of Cisco being toxic, poisonous or venomous. That is not proof that it is safe. Never eat, touch or handle a wild plant, mushroom or animal on the strength of an identification; ask someone qualified.
