Net Systems – Bongo

The Bongo Paired Plankton Net System, Series 1200 is a sophisticated sampling device that is capable of multiple-unit, simultaneous sampling at mid-ocean depths as well as a reliable single-unit tow platform for use in shallow water sampling. One of the unique features of the Bongo system is its opening and closing mechanism that allows discrete “known-depth” sampling. The system has no frontal obstructions to frighten, disturb, or damage the catch and is large enough to filter water at the rate of 47.5m3/minute when towing at a speed of two knots.

A bongo net consists of two plankton nets mounted next to each other. These plankton nets are ring nets with a small mesh width and a long funnel shape. Both nets are enclosed by a cod-end that is used for collecting plankton. The bongo net is pulled horizontally through the water column by a research vessel. Using a bongo net, a scientist can work with two different mesh widths simultaneously.

Because of the Bongo’s simple design and rugged construction, the unit is almost maintenance-free.

We manufacture the 1200 series Bongo net system in several sizes. The only difference in the models is frame size or hoop diameter, measured in centimeters. When requesting a quotation for a Bongo system, please indicate the diameter and net mesh that you prefer, along with the filtration ratio of the nets. When you purchase a complete Bongo system, all nets, doors, and cod ends are rigged and tested prior to shipment to ensure proper operation.
