| Definition | A rod of wood or pipe is outfitted with a combination wire clamp and closing release at the top and a pair of snap hooks at the bottom, one to secure the device to the wire and one to secure the bottom portion of the net. Attached to the rod is a net with a bridle which inserts into the release latch. Midway along the pipe is a second snap hook which is attached to the mid section of the net. Multiples of these units may be attached to the wire at various depth intervals as the wire is lowered vertically into the water. Plankton collections are made as the nets are hauled up until a messenger hitting the release lets the bridle go, thus closing the net [Wiebe and Benfield 2003 Plate 5 B]. | ||
