The plankton trawl with a 10-layer mesh has a mesh area of 1m2 and a mesh aperture of 100 mm.

Maximum working depth: over 4000m; The towing speed is from 1 to 5 knots, and the sensor such as flow meter, dip Angle sensor, and environmental parameters can be selected, which has parameters such as temperature, salinity, pressure and height from the bottom.

With deck power supply, it can be controlled by cable in real time, with remote data transmission system and deck monitoring system, it can be opened and closed manually on deck, or it can be towed by stainless steel cable. The arrangement of the equipment is not affected by the direction of wind speed, current and ship direction. The depth is generally kept at a certain value, and the variation range is less than 0.5 meters, which has reduced the influence of the current on the depth and the drag posture to a minimum.

The second research institute of the state oceanic administration introduced the system in March 2008, and it was successfully used in the ocean survey of the 20th voyage of the ocean-1 ship.
