Design of signalling
color patterns in fast-moving objects, including blades of spinning lures, must
be grounded upon the following 4 basic rules:
must be bilaterally symmetric
stimuli must be located closer to the center of rotation
3) red colors are rather than blue ones
must be simple
information, see On the coloration of fast-moving
signalling stimili in the nature
water, blades of spinning lures form clearly visible conical bodies of rotation
with an angle of rotation, depending on spinner construction and velocity of
retrieving, from 30o to 60o. The linear velocity of any
spot located at R distance from the axis of rotation is v = 2πR/T, where T is
an interim of one turn. If, say, the blade makes one turn per second and R =
0,5 cm, the linear velocity of this spot will be about 3 cm/sec. Generally, blades
of spinning lures may make several turns per second, and rotation radii of
spots may achieve 2-3 cm for lures of middle size. It means (for general principles, see Stojcev et al., 2011) that fish will see as flashing and colored only
those spots, which are located as close as possible to the axis of rotation (with
the lowest v).
For example, click here to see how Mepps spinners move (at the constant velocity) in the water.
to the laboratory experiments (Gehres & Neumeyer, 2007; Stojcev et al.,
2011), fish (goldfish, Carassius auratus) see fast-moving (7 cm per second) red and blue discs as colorless.
given bellow shows some color pattrens desined on the ground of the foregoing rules.
patterns can be used for face (convex) and back (concave) surfaces of the
we are looking for world manufacturers to produce spinning lures with the
foregoing and similar color patterns.
