  • a cylindrical fishtrap which is provided with hoppers on both ends for guiding fish into the fishtrap, has been proposed and used.
  • paste bait for a decoy is applied to the hoppers of the fishtrap prior to carefully setting the fishtrap in the water of a river or reservoir.
  • Fish, which intrinsically swim upstream and are lured by the paste bait smelling like sesame, are guided into the fishtrap through the hoppers and are prevented from escaping.
  • the fishtrap is pulled out of water after a predetermined time so that the fish are easily caught.
  • the typical fishtraps have been generally manufactured by an injection molding process of synthetic resin.
  • the typical injection molding process for manufacturing the fishtraps has an advantage in that the process easily forms fishtraps of various configurations because the process is performed using injection molds, which are easily shaped into a desired configuration and construction.
  • the fishtraps manufactured by the injection molding process must be thickened in order to prevent cracking of the fishtraps.
  • the typical injection molding process for manufacturing the fishtraps has problems in that it not only provides added weight to the fishtraps, it also wastes the synthetic resin and thereby increases the cost of the fishtraps.
  • the fishtraps manufactured only by the injection molding process have a bad transparency due to both their thickness and the intrinsic characteristics of the synthetic resin.
  • the above fishtraps have a bad thermal resistance and bad cold temperature resistance.

Abstract

L'invention concerne un procédé de fabrication de pièges à poissons. Ces pièges à poissons sont bon marché, présentent une bonne transparence et une haute résistance. Selon le procédé, les première et seconde parties (10, 20) du piège à poissons sont moulées en une seule structure, par extrusion-soufflage. Cette structure est à son tour divisée en deux pour fournir les première et seconde parties du piège à poissons. Les première et seconde parties sont ensuite perforées, pour former une pluralité de trous (12, 13, 22, 23). Les pièges à poissons sont, de préférence, en polyéthylène-téréphtalate. La liaison entre les première et seconde parties du piège à poissons est assurée par des parties filetées femelle et mâle (11, 21). Les parties filetées sont séparées et se retrouvent respectivement sur la première partie et sur la seconde partie du piège à poissons, lorsque la structure unique est divisée en deux parties respectives.
