PCT No. PCT/AU90/00101 Sec. 371 Date Nov. 5, 1991 Sec. 102(e) Date Nov. 5, 1991 PCT Filed Mar. 8, 1990 PCT Pub. No. WO90/10384 PCT Pub. Date Sep. 20, 1990.A shooting mechanism for depositing a fish trap into a body of water including a U-shaped main support frame (60) pivoted to a fishing vessel so as to extend outwardly from the vessel over the water. Two support gates (62, 63) are hinged for movement about a longitudinal direction so that the gates (62, 63) provide a support platform for the fishing trap, the two support gates (62, 63) hinging to their retracted positions simultaneously to allow the fishing trap to fall downwardly between the support gates (62, 63) and into the water. Also disclosed is a fish trap including a generally rectangular rigid base (10); a rigid front wall frame (14) which has a pivotal connection (14a) to the base (10) so as to be collapsible to lie generally flat upon the base (10); a back wall frame (15) with a pivotal connection (35) to the base (10) at a rear pivot position enabling the back wall frame (15) to be pivotally movable to an erected position. The pivotal connection (35) of the back wall frame (15) is selectively detachable from the base (10 ) enabling the lower portion of the back wall frame (15) to be moved generally towards the front wall frame (14) to a forward pivot position (37) and enable the back wall frame (15) to be pivoted downwardly about the forward pivot position (37) so as to lie generally flat upon and substantially within the boundaries of the base (10). A brace (42) is connected to the front wall frame (14) and extends downwardly and rearwardly from the front wall frame (14) to the base. The front wall frame (14) is connected to the back wall frame (15) by a flexible tether (51, 40). A retrieval apparatus for mounting to a fishing vessel is disclosed for use in retrieving a fishing trap (102) from a body of water and including an upright guide (100) for a fishing trap (102) being retrieved up the side (101) of the vessel.
