Fishing is exploitation.
It interferes with both nature itself and other peoples' enjoyment of it. Foreign, introduced, not native fish, e.g. European carp, Loach, Pacific Oysters. Limits should include a prohibition on the taking of endangered species. Similarly, the Wilderness Act should be amended to provide for the prohibition of fishing. Where the National Parks and Wildlife Service Estate or wilderness is adjacent to marine or estuarine waters, its boundary should extend to Mean Low Water Mark, in order to give the NPWS full permanent authority over the intertidal area.
