plankton net

A plankton net is a specialized device used by scientists to collect tiny plants and animals—collectively called plankton—from the water. It typically consists of a fine mesh or net mounted on a frame, which is towed behind a boat or moved through the water. As water flows through the net, the small organisms are trapped on the mesh, allowing researchers to study the variety and quantity of plankton in a specific area. This helps scientists understand aquatic ecosystems, food chains, and the health of oceans and lakes.
