Fishing licensing and regulation allows for more effective protection for species and their habitats. The ability to better protect, conserve, and enhance fisheries and wildlife resources is crucial for our native species. DDOE develops and enforces regulations in coordination with the District's Metropolitan Harbor Police and the Capital Park Police. This has contributed to the tremendous water quality improvements in the Potomac River and signs of improvement in the Anacostia River resulting in an increase in the numbers of game fish, including bass, crappies, and yellow perch.
