Bowfin

(Amia calva), the only living representative of Amiidae of the superorder Holostei. The bowfin grows up to 60 cm long. The scales are cycloidal; the air bladder is alveolate and serves as a supplementary breathing organ. The fish inhabits shallow, extremely overgrown, and marsh-ridden bodies of water of North America, south of the Great Lakes. It feeds on invertebrates and small fish. The bowfin spawns in spring; the male builds the nest and guards the eggs and young. The newly hatched fish have an adhesive organ on their heads, with which they attach themselves to the nest walls. The female lays 20,000–70,000 eggs. The bowfin has almost no commercial value.

Included in the state fish fauna are: one native species (longnose gar) that has been extirpated from New Jersey waters; 19 species that are known to be not native and to have been introduced to New Jersey, of which three (goldfish, common carp, grass carp) are native to Asia and Eurasia and 16 to other areas of the eastern United States and adjacent Canada; and 66 species that are presumably native, although three (bowfin, eastern mosquitofish, warmouth) of these species are so listed tenuously because one or more of them might have occurred, or been introduced (as the first two of these three species are known to have been), or both.
