Soft cages are easy to transport and harvest. However predators like minks, otters, and snapping turtles may be able to chew through the soft cages. Cage Materials Frame Plastic mesh or netting Feeding ring Lid Flotation A feeding ring is used to prevent floating fish food from passing through the cage. The lid for the cage can be constructed from the same type of netting as the rest of the cage. The advantage of constructing the lid from netting is that feeding is made easier because the feed is thrown directly into the cage without removing the lid.
Flotation is necessary to maintain the top of the cage just above the water surface.
Flotation can be provided by styrofoam, waterproofed foam rubber, or sturdy plastic jugs. Milk jugs tend to break down due to prolonged exposure to sunlight. The frame when constructed of polyethylene or PVC pipe will provide adequate flotation.
