A plankton sampler comprises a gathering net coupled to and in communication with a container having an inlet at one end and an outlet in its side through which water may flow outwardly of the container. Removably accommodated in the container is a screened sample collector, the screen of which is of such size in relation to that of the container that an annular space is provided between the collector screen and the inner surface of the container, thereby enabling water to flow outwardly from the collector into the annular space and thence through the opening in the side of the container.
