Quick Answer
Funnel traps are enhanced by features such as a narrow entrance, a smooth and steeply sloping channel, and a collection point or basket to catch fish. These features guide fish into the trap, allowing for efficient fishing.
Designing the Funnel Entrance
The narrow entrance of a funnel trap is crucial in guiding fish towards the collection point. A funnel entrance with a width of 10-20 cm (4-8 inches) and a length of 1-2 meters (3-6 feet) is ideal for most fish species. The entrance should be oriented in the direction of the current, allowing fish to swim easily into the trap.
Sloping Channel and Collection Point
A smooth and steeply sloping channel with a slope of 10-20 degrees is essential for directing fish into the collection point. The channel should be 1-2 meters (3-6 feet) long and 20-30 cm (8-12 inches) wide. A collection point or basket with a mesh size of 1-2 cm (0.4-0.8 inches) is effective in catching fish. The collection point should be positioned at the end of the channel, allowing fish to swim into it easily.
Additional Features and Techniques
Rock or log barriers can be used to direct fish towards the funnel entrance. Bait, such as fish oil or fish guts, can be used to attract fish to the trap. The funnel trap can be built in a way that it is partially submerged in the water, allowing fish to swim into it easily. The use of a sacking or netting material can help to prevent fish from escaping from the collection point.
