BONGO NETS
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.
