Quick Answer
Gill nets are regulated in certain bodies of water, and their use is often prohibited or restricted in lakes and ponds due to concerns over fish populations, habitat disruption, and bycatch.
Laws and Regulations
Laws and regulations regarding gill nets vary by country, state, or province. In the United States, for example, the Federal Government regulates gill net fishing in waters under federal jurisdiction, while individual states regulate fishing in their waters. In freshwater lakes and ponds, many states prohibit the use of gill nets altogether, while others may allow their use with permits or specific mesh sizes.
Gill Net Construction and Mesh
A traditional gill net is constructed by creating a net with a series of vertical panels, or meshes, made of monofilament or multifilament nylon. The mesh size, measured in inches, determines the size of the fish that can pass through it. For example, a 4-inch mesh will allow small fish to pass through but will catch larger fish. In some cases, gill nets may be restricted to specific mesh sizes, such as 6 inches or larger, to reduce bycatch and protect smaller fish species.
Materials and Techniques
Gill nets can be constructed using various materials, including monofilament or multifilament nylon, or even plant-based materials like cotton or jute. The mesh size and material can affect the durability and effectiveness of the net. Primitive fishing nets, like dip nets or seines, can be made using simple materials like twine or cordage, and may not require the same level of regulation as gill nets. However, even these nets may be subject to local regulations and restrictions.
