Pike is very loyal and stays in same place as a hermit. In very small measure pike moves in its territory. When you catch a pike, so after few days, there is a new pike in that territory.
It is worth fishing pikes in the same places where you have got them, because new pike takes over fished territory.

Here in Finland pike is undervalued fish. Pike's flesh is less greasy and good to eat and very healthy. Fortune to pike hunt!
