Conder (fishing)

In English fishing customs, a conder, also called a huer or bulker, was a person who stood on high places near the sea coast, in times of herring-fishing, to signal to the fishers which way the shoal of herrings or pilchards passed—their course being more discernible to those who stand on high cliffs, due to the blue color they cause in the water, than to those aboard vessels.

The term was also used to refer to the raised location where a conder stood.
