AQUATIC ANIMAL CAGE AND FABRICATION METHOD

摘要

An enduring cage for fish or other aquatic animals is provided. The structure of the cage is such that it can be made of deterioration-resistant materials at a reasonable cost. The cage has a top frame made of bent aluminum tubing or pipe. The tubing is slit so that it has a horizontal gap or slot into which are inserted the upper edges of flexible netting side walls. The top frame is strengthened by the use of: an aluminum top sheet inserted into the same slot as the upper edges of the netting and forming a partial cover for the top of the cage. The tubing then is clamped, by means of bolts inserted through holes in the tubing, and the edges of the netting and the top sheet. The netting and top sheet are held tightly and evenly in place. The side walls and bottom of the cage are made of netting panels which are fastened together at their edges to form seams. The seams are formed by slitting conventional polyethylene tubing, inserting the edges of two side walls into the tubing, and stapling through the tubing. The cage preferably has flotation material to support the cage on a body of water with the top above water. The cage also preferably has a hinged aluminum lid with a hole through which feed can be deposited into the cage.
