Gill nets are a type of fishing gear made of mesh netting that captures fish by their gills. The net is set vertically in the water, allowing fish to swim into it. Once they attempt to escape, their gills get caught in the mesh, preventing them from swimming away. Gill nets can vary in size and mesh opening, depending on the target species. These nets are commonly used in both commercial and recreational fishing. While effective for catching fish, gill nets can also unintentionally trap non-target species, leading to concerns about bycatch and environmental impact. Proper management and regulations are essential to minimize these effects.
