- Name
FishWeir- Kind
- FeatureType
- Definition
- A fence of stakes or wall of stones set in a river or along the shore to direct fish towards fish traps or nets.
- Description
- The weir is shaped so as to encourage fish to naturally congregate, usually based on river or tidal flow. Although generally consisting of linear segments on rivers, in shore areas one or more components may be curved so as to form an enclosure with a narrow entrance. When constructed of stones the thickness of the wall constitutes a permanent hazard to maritime navigation.
