Abstract: A supporting structure for a fish net or the like including a plurality of vertically extending supporting elements projecting, at least partially, above the water surface. Elongate connecting elements extending generally parallel to the water surface are releasably connected to the supporting elements to form a frame. A fish net is secured to the connecting elements, and is retained at a predetermined level relative to the water surface by inflatable members mounted upon the supporting elements. The connecting elements and supporting elements retain the inflatable members at fixed predetermined distances from each other.

Abstract: An animal food dispensing apparatus comprising a container with a bottom opening and an insert suspended in the opening. The insert is in the form of a sleeve open at its upper and lower ends. A vibrator is mounted within the sleeve and has a vibrating portion extending through the lower sleeve opening. The vibrating portion is attached to a food dispensing plate which extends across the lower sleeve opening and is spaced below it. When the vibrator is energized, food will fall from the edge of the plate.
