Abstract: 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.
