Instead, it is recommended to use a rod designed specifically for fishing for small fish, such as a spinning rod or ultra-light rod. These rods are lighter, shorter, and more sensitive, making them better suited for fishing for smaller fish. They are also typically equipped with smaller hooks and lighter lines that are more appropriate for these smaller species.
So, while it's possible to fish for small fish with a carp rod, it's not generally recommended and is not the most effective or enjoyable method.
