Community fishing vessels shall also notify representative samples of length composition measurements of the target species and by catch species from the fishery (form B2, latest version). Length measurements of fish should be of total length to the nearest centimetre below and representative samples of the length composition should be taken from a single fine scale grid rectangle (0,5° latitude by 1° longitude). In the event that a vessel moves from a fine scale grid rectangle to another during the course of a month, then separate length compositions should be submitted for each fine scale grid rectangle.
