Practically all manufacturers of fishing spinners offer some tens of blade design patterns and, of course, all these patterns are posinioned as effective. In fact, at the typical velocity of movement of spinners in fishing and, in turn, the corresponding velocity of blade rotation, the most part of these patterns is non-functional.

Figure given below illustrates an usable visual tester that allows you to trace how one or the other blade design pattern changes depending on the velocity of blade rotation. The tester is like an ordinary toy whirligig. Paper applications with the blade design patterns or even metal blades you would like to verify are sticked to the flat transparent sector of the tester.

 

One of the most known and applicable blade design patterns, with the silver holographic back and red spots, is shown. For illustartion, only one blade is given. In general case, you can stick two, three (placed symmetrically) or six blades, identical or non-identical.

Rotating the foregoing tester with the six red-spotted patterns, you will see with increasing the velocity of its rotation the following typical picture:

1) clear flashing of the red spots

2) merge of the red spots into the reddish circles

3) merge of the reddish circles into an aureole of lighter reddish color

4) finally, an aureole will become colorless.

For example, click here to see how Mepps spinners move (at the constant velocity) in the water.

According to the laboratory experiments (Gehres & Neumeyer, 2007; Stojcev et al., 2011), fish (goldfish, Carassius auratus) see as colored only slow-moving (2-4 cm per second) red and blue discs.

The so called critical frequency of flash fusion (CFFF) in Northern pike, Esox lucius, (28 flashes per second) and human (18-24 flashes per second) are sufficiently close (Protasov, 1978). In adult roach, Rutilus rutilus, CFFF is essentially less (16 flashes per second) (Sbikin, 1980). According to the same author, in perch, Perca fluviatilis, CFFF is higher (33 flashes per second). It means (reviwed by Protasov, 1978; Sbikin 1980) that prech are able to discriminate flashing of visual objects at the higher velocity than human, pike, E. lucius, roach, R. rutilus, and other fish.

Currently, we are looking for world manufacturers to produce the foregoing testers, printed applications and manuals. Moreover, we are interesting in co-operation with software developers to create the corresponding computer program.

Juvenile individuals of yellow perch, Perca flavescens, demonstrate clear antipredatory behaviour in response of the alarm pheromone contained in the skin of conspecifics (Mirza et al., 2003; Harvey & Brown, 2004). In contrast, adult perch (of length more than 11 cm), which are in the nature chiefly piscivorous, demonstrate foraging behaviour in response of the same cues (Hurvey & Brown, 2004).

Yellow perch, Perca flavescens (powered by Joseph Tomelleri)

This ontogenetic shift in response of yellow perch to conspecific alarm cues can be used in fishing. Using the same skin extract of perch, you can try to repel small perch and attract large perch simultaneously.

Remove the skin (with scale) from both sides of two-three perch of medium size and carefully grind it in the pounder with pure water. Then dilute the mixture to about 100-150 ml, filter and pour it into the suitable plastic bottle with dropper (for more details, see Harvey & Brown, 2004).

To apply the skin extract in perch selective fishing, you can use your favorite wobblers with the additionally sticked strips of soft porous materials or, say, add the soft porous containers to your rigs to fish on live prey.

Currently, we are looking for world manufacturers to produce the necessary chemicals, rigs and lures with the accompanying manuals for American and other markets Not only for fishing. Rather not for fishing. These products may be more successfully used in the naturalistic clubs, schools, colledges and universities in the capacity of educational equipment.

Other pheromones can be added.
