Key freshwater plants and some used plant-related tools of recreational fishers. a Germinating fruit of Trapa natans identified by an angler [Keleti Main Canal]; b well-known, but unnamed sprout of Myriophyllum spicatum removed from the hook [Lake Látóképi]; c River bed clearing with a long wooden stick by an angler to avoid hooking to plants anchored into the mud during fishing [Keleti Main Canal]; d an installed branch against floating aquatic plants in the front of a private fishing pier. The branch leads floating plants to the middle of the riverbed, thus keeps the water clear in the front of a fishing pier [Keleti Main Canal]; e an angler shows the spared population of the protected Nymphaea alba in the front of his fishing pier [Keleti Main Canal].
