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).

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).
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
Other pheromones can be added.
