Using a length of string or fishing line ( not included ), some tasty bait and a bit of patience and you can catch that pesky fish.
Acrylic cylinder is 5 inches in diamter and 6 inches in length. Square panels at both ends for balance, one end has a sliding door.
Best results are when the trap has been introduced for a couple of days so the fish become familiar with it. Place a small amount of their food inside the cylinder with the door shut. After a day of tempting the fish hold open the door with a some string and simply wait until the desired fish enters the trap and let the door slide shut. You can now easily lift out the fish.
