A device designed to capture crustaceans, primarily crabs, is a common tool in both recreational and commercial fishing. These devices typically consist of a frame constructed from metal or plastic, enclosed with mesh or netting, and equipped with one or more entrances that allow crabs to enter but hinder their escape. Bait is placed inside the enclosure to attract the target species. An example is a square-shaped wire cage with funnel entrances leading to a central bait compartment.
The employment of these enclosures offers several advantages. They provide a relatively efficient method for harvesting crabs, allowing fishers to target specific areas and depths. Historically, their use has played a significant role in the crab fishing industry, contributing to the livelihoods of many coastal communities. Furthermore, when used responsibly and in accordance with regulations, these devices can be a sustainable fishing practice.
