Licensing and Regulation 
Licensing and regulation gives managers regulatory influence over species and their habitats to better protect, conserve, and enhance fisheries and wildlife resources. This division develops and enforces regulations in coordination with the District of Columbia'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 largemouth, smallmouth, striped bass, crappies, and yellow perch.

Fishing regulations have helped to minimize the exploitation of the District's fisheries resources. The District introduced regulations that limit the size and number of a select fish species that anglers are allowed to keep. Surveys of migratory and resident fish, fish habitat, fish health, and anglers' practices are conducted. These activities provide valuable information to better understand and advance the efforts to increase the number and diversity of fish in its waters.
