As typical microsmatic visually guided fish, pike, Esox lucius, and other representatives of Esox genus do not respond to food odors (Devitsyna & Malyukina, 1977).

Pike larvae decrease the frequency of attacks on zooplankton prey and show other anti-predator responses on chemical cues of Eurasian perch, Perca fluviatilis (Lehtiniemi, 2005; Lehtiniemi et al., 2005). Chemical cues of perch (water from under adult predators, 15 cm length, fed on pike larvae until experiments) affect alone, but chemical and visual cues offered together are more effective.

Among pheromones, pike are respond to the conspecific sexual pheromone (Devitsyna & Malyukina, 1977).

Furthermore, it is shown that pike are attracted by alarm pheromone of fathead minnow, Pimephales promelas (Mathis et al., 1995; Chivers et al., 1996; indirect data by Wisenden & Thiel, 2001). In addition, pike demonstrate distinct foraging responses to artificial hypoxanthin-3(N)-oxide (Mathis et al., 1995) identified as an active component of ostariophysan fish alarm pheromones.


 

On this background, Marcel Van Den Eynde offers the predator, inluding pike, attractants under the mark Predator Plus.

The exact composition of this attractants is unknown. As feeding attractant (with food extracts, amino acids and related chemicals), it cannot work. Nothing is known whether pheromones are included.

On this background, Daiwa Cormoran Co., Germany, offers the pike attractant Double Fish.

The exact composition of this attractant is unknown. As feeding attractant (with food extracts, amino acids and related chemicals), it cannot work. Nothing is known whether pheromones are included.
