This is without a doubt the most extraordinary fishing book I know.
The approach is completely new. No generalizing assumptions are made, no repetitive water sketches with fish silhouettes on the reed belt and perch mountain + surefire baits are thrown among the readership.
No, in painstaking work the authors have collected vast amounts of scientifically sound facts about the life, habits, and preferences of the pikeperch and drawn the right conclusions from them. The advice with the lifting is so good, this clearly results in more fish.
Great book!
