Description
The Bongo net was invented in the mid-20th century. Today, bongo
nets are available both in opening/closing and non-closing
form. However, the most commonly used net is a non-closing
MARMAP Bongo Net, developed around 1980.

How It Works

A pulley with a 19 mm diameter chain or cable is used to lower
the nets into the water column. A collecting bucket, attached to
the cod-end of the net, is used to contain the zooplankton
sample. Finally, when the net is retrieved from the ocean, the
collecting bucket can then be detached and easily transported to
a laboratory.
