Designed for passive sampling of larval fish and macroinvertebrates, this compact, rugged trap is suitable for use in lotic, lentic, and hatchery environments. The trap is comprised of a flotation block, a cloverleaf-shaped array of clear polycarbonate tubes, a center tube that houses a light source such as a chemical lightstick (not included), and a collection assembly. This trap’s sampling method takes advantage of the phototactic behavior of many aquatic organisms by using a bright light to lure organisms inside the cloverleaf array. Organisms are then confined unharmed. As the trap is lifted, the sample is concentrated in a detachable collection basin lined with 250 micron mesh.
