Re: Carp flies and tactics
Those pheromones are actually not released simply because the fish is spooked. In other words, if you spook a fish and he bolts, the pheromones most likely have NOT been released.
They are called Alarm Substance Cells (ASC) and actually more of a mechanical release. If you grab a carp or step on one, then those ASCs would be released because you would be physically rupturing those cells. To sum that up, those cells are only released when physically ruptured.
With that knowledge, if you spook a fish from the area, sit tight, the fish will be back.
