Abstract
The Weedless Fish Structure is a simple, waterproof, hardened acrylic structure that is submerged in water to provide camouflage and shade cover for game and feeder fish in areas where the body of water does not provide adequate cover. The weights within the main tube allow the apparatus to rest on the bottom with little buoyancy. A small air tube edges around the semi-circular bifurcated shade fin and provides buoyancy to the top fin so it remains upright. Two stakes are provided to secure the apparatus to the bottom when desired to prevent currents from moving the device. If the structure is turned over to where the long tube is above the shade fin, the weights will slide down into the shade fin tube and the air will rise into the long main tube, and then by attaching two floats, the structure becomes a surface apparatus. A photo image of underwater vegetation, sandwiched between the acrylic sides of the shade fin provides additional concealment for fish and a more natural appearance to attract fish to hide on either side of the shade fin in sunny or shaded conditions.
