Which of the following is an approved device to catch animals?

Foot hold traps are an approved device for capturing animals as they are specifically designed to safely restrain an animal without causing significant harm. These traps are regulated by wildlife management agencies to ensure they comply with humane standards. They work by securing the animal's foot, allowing for safe handling and potential relocation if necessary, rather than killing the animal outright.

While other devices mentioned may be used for specific contexts, they do not have the same level of recognition or approval for general use in wildlife control. Aquatic nets are often used for fishing rather than trapping wildlife on land. Pitfall traps, though effective in certain situations, can lead to drowning or injury, which raises ethical concerns about their use in wildlife control. Live bait captures could refer to methods that are typically less controlled and could potentially involve using unintended species. Thus, foot hold traps are recognized within nuisance wildlife control for their effectiveness and adherence to humane practices.
