These species must be destroyed when encountered. There are ten species of fish whose presence is considered to pose a serious threat to the state’s freshwater resources and are identified and regulated as potentially dangerous. Several species, such as Channel Catfish, Hybrid Striped Bass, Muskellunge, Northern Pike, and Walleye, which do not reproduce as readily in New Jersey, are maintained through active stocking programs for recreational opportunities. There are 17 introduced species, 11 of which are popular game species, a number of which have become naturalized and are commonly found in both lakes and rivers throughout the state. American Eel, on the other hand, are catadromous reside throughout fresh waters of the state but migrate to the Sargasso Sea to spawn. One other species, the Sea Lamprey, may reside for years as juveniles in freshwater before migrating to marine waters, only to return to freshwater in the future to spawn. These species, Alewife, American Shad, Blueback Herring, Hickory Shad, and Striped Bass are anadromous, living predominantly in marine/brackish waters but migrate into fresh water in the spring to spawn. Five species are truly migratory and are present only seasonally in fresh waters of the state. Of these 90 species, 60 are native to the state. There are 90 species of freshwater fish found in New Jersey waters.
