When provided with a long handle, this net may be used from the shore, and is particularly recommended for burrowing nymphs of aquatic insects. Rake net. The rake net consists of an ordinary garden rake, with a stiff semicircle of wire fastened on the upper side of the rake above the teeth. This should be braced to the handle with another piece of wire. A net is then attached to the upper part of the rake and around the semicircle of wire.
