A bag net mounted on the support member is adapted to receive and hold shellfish collected from the bed by a rake. The rake is carried pivotably by and extends between the runners and has a pivot shaft with a plurality of substantially parallel spaced tines thereon. At least one of the runners has an upwardly extending columnar member with at least one aperture therein, the pivot shaft being journaled in the columnar member and having an adjusting arm secured to at least one end of the pivot shaft for rotation therewith. One end of the adjusting arm has an offset section in which a plurality of apertures are formed alignable with the at least one aperture in the columnar member. A fastening device is insertable through the aligned apertures of the corresponding columnar member and adjusting arm for fixing the shaft and the tines in predetermined angular relation to the bed of the body of water.
