Fenced, netted structure fixed to the bottom substrate and allowing free water exchange; in the intertidal zone, it may be solid-walled; the bottom of the structure, however, is always formed by the natural bottom of the waterbody where it is built; usually coastal e.g. in shallow lagoons, but also inland e.g. in lakes, reservoirs. A pen generally encloses a relatively large volume of water.
