<p>A method for manufacturing fishtraps is disclosed. The method manufactures the fishtraps at a low cost and provides the fishtraps of a good transparency and high strength. In the method, first and second fishtrap parts (10, 20) are molded into a single structure by a blow molding process. The single structure in turn is divided into the first and secnd fishtrap parts. The first and second fishtrap parts are, thereafter, punched in order to form a plurality of holes (12, 13, 22, 23). The fishtraps are preferably formed of polyethylene terephthalate. The junction between the first and second fishtrap parts is provided with female and male screw portions (11, 21). The screw portions are separated from each other and belong to the first and second fishtrap parts, respectively, when dividing the single structure into the respective fishtrap parts.</p> |
