Ruffe are also vulnerable to diseases and predators such as birds, snakes, and larger fish. It is important to protect ruffe populations to ensure the sustainability of the aquatic ecosystem. Anglers should adhere to size and weight limits to help protect fish populations and their habitats.

Question 10

How to fish for ruffe?

Accepted Answer

Fishing for ruffe can be an engaging activity for sport fishermen. It is recommended to use live bait such as worms, larvae, and shrimps, which mimic the natural prey of ruffe.
