Quick Answer
Modify a standard basket trap by adding a bait container with a release mechanism, incorporating a funnel or V-shaped entrance, and attaching a trigger stick or spring-loaded trigger to automatically close the trap.
Enhanced Entrances
A funnel or V-shaped entrance can significantly improve the efficiency of a basket trap. This design allows fish to swim in easily but have difficulty swimming out. A 30-degree angle is ideal for the funnel, as it prevents fish from jumping over the entrance. The width of the funnel can be adjusted to suit the target species, with a minimum width of 6-8 inches for smaller fish.
Bait and Release Mechanisms
Including a bait container with a release mechanism can help maintain bait freshness and prevent accidental release of trapped fish. A simple design involves attaching a small container to the side of the basket using a hinge and a trigger stick. When a fish is caught, the trigger stick is triggered, releasing the bait container and allowing the trapped fish to be removed.
Spring-Loaded Triggers and Automatic Closures
Spring-loaded triggers or automatic closures can be used to release the trap quickly and humanely. A simple design involves attaching a spring to a trigger stick, which is released when a fish bites the bait or triggers the trigger stick. This design can be adapted to various types of basket traps, including those used for building fish weirs and rock weirs.
