As with other countries, the 200 nautical miles (370 km) exclusive economic zone (EEZ) off the coast of the United States gives its fishing industry special fishing rights.

The latter is largely caused by plastic-made fishing gear like drift nets and longlining equipment that are wearing down by use, lost or thrown away.
