Just to clarify...Bowfin and Burbot are completely different species. Bowfin are a warm water fish usually found in shallow weedy water, while Burbot are cold water fish usually found deep.
Yes, Bowfin are commonly called Dogfish, and Burbot are called a number of names depending on the region...Ling, Eelpout, Lawyerfish.
Burbot are great eating...they're also known as "Freshwater Cod"...sweet, white flaky meat. I often catch them incidently ice fishing for Walleye or Lake Trout/Whitefish...they make for a delicious meal of fish and chips.
