Rakolovka or rachnitsa . Rakolovki happen several kinds. The elementary rakolovka consists of a metal hoop and poorly tense sagging grid with cells 20х20 mm. A bait put in the circle centre. More difficult and more effective rakolovka consists of two metal circles: in one diameter about 0,8 m, the second - 0,5 or 0,4 m. Circles together with a grid should form the truncated cone in height about 200 mm. This tackle in working position at the bottom reminds an inkwell "neprolivajku". A bait or suspend in the centre of the top, small circle, on a delay, or lower inside on a bottom of the big circle. The cancer rises on a cone-shaped wall, falls in rakolovku, trying to reach a bait. One more kind rakolovki represents a metal mesh cage of the trapezoid form. Grid walls (one, two or even all) at cage lowering on a bottom reveal. At lifting rakolovki they by means of cords develop in a trap-cage.
Catch cancers from coast, from surface constructions or from a boat. From coast catch usually most simple rakolovkoj, adhering it to a pole. At catching from surface constructions or from a boat rakolovki on three or four leads-slings which bundle and krepjat to a long cord, lower on a bottom. To find rakolovku, the top part of a cord adhere to penoplastovomu to a float-signalling device. At displayed rakolovki the cord should be more depths of a reservoir, differently rakolovka will not reveal. At konusovidnoj rakolovki there where slings converge in knot, becomes attached penoplastovyj a float which on load-carrying capacity should be sufficient that rakolovku to hold in working position (the cone should be tense). Above on a cord the float-signalling device also fastens. As a bait dead fish from the given reservoir, and also fish frozen or salty, bought in shop, a meat waste is put. Frogs and others useful amphibious for these purposes to use n
e it is necessary.
