Neogobius melanostomus (Round goby)

Animal Fish
Family: Gobiidae
Classification: Prohibited

The round goby is similar to native sculpin in appearance and ecology. They may be found in marine, brackish, and fresh water. The goby spawns several times a year. Once introduced the population grows quickly, taking over prime habitat and spawning areas. They prey upon the eggs and fry of other fish, and may have impacts on sport and commercial fishing. In areas where they have become abundant, they have had serious impacts on sculpin populations.
