A fishing weir, or fish weir, is an obstruction placed in tidal waters or wholly or partially across a river, which is designed to hinder the passage of fish. Traditionally they were built from wood or stones. They can be used to trap fish. For example, salmon and other fish can be trapped when they attempt to swim upstream, or eels can be trapped when they attempt to migrate downstream.
Alternatively, fish weirs can be used to redirect fish elsewhere, such as to a fish ladder.
As fish traps, fishing weirs date back to the Bronze Age in Sweden and to Roman times in the UK. They were used by native North Americans and early settlers to catch fish for trade and to feed their communities.
Famous quotes containing the words fishing and/or weir:
“O mud
For watermelons gutted to the crust,
Mud for the mole-tide harbor, mud for mouse,
Mud for the armored Diesel fishing tubs that thud
A year and a day to wind and tide; the dust
Is on this skipping heart that shakes my house,”
—Robert Lowell (1917–1977)
“The first thing to be done by a biographer in estimating character is to examine the stubs of his victim’s cheque-books.”
—Silas Weir Mitchell (1829–1914)
