In 2013, there were 2,661,890 registered nurses in the U.S. working in a wide range of medical environments and facilities, some with specialties such as critical care. According to the American Association of Critical Care Nurses, only 67,040 CCRNs were working in the United States in 2014.
The first is known as a reduction fishery. The second is known as a bait fishery, which harvests menhaden for the use of both commercial and recreational fishermen. Commercial fishermen, especially crabbers in the Chesapeake Bay area, use menhaden to bait their traps or hooks.
A related concern is that low recruitment of menhaden may be affecting the species' ability to serve as a major food source for other fish. Many recreational anglers contend that the poor nutritional condition of striped bass in Chesapeake Bay in recent years is linked to insufficient forage (menhaden) supply.
