A person is walking in the water with a net.
The fisherman uses many tools.
It is reasonable to suppose that a person walking in water with a net might be a fisherman; many who fish use a variety of tools including hooks, lines, poles, flies, winches, harpoons, explosives, etc., so at the very least this is a reasonable statement to reflect on fishing in general, even if it DOES NOT strictly follow from a sparsely-described image.
