Hello,
all large enough pikes are always an interest to people dedicated to fishing. Even those who are claimed to be large, such as the one from Hoppy4. Without any doubt in my mind, that pike does not weight 20kg, far from it, as you can clearly divise from the picture. This very pike is discussed at http://www.fiskesnack.com
Currently the thread has 48 replies and above 1,300 views. Not anyone of them think that it has the weight that was claimed, they believe the weight is around half of what is claimed here. The thread is called "20kg gädda". If you want to view some pictures of Swedish pikes you can visit their excellent picture gallery called "Fotoalbum", you can there click the link called "Gäddor" which will direct you to 2,604 pictures of pikes, many of them have the same size as the pike Hoppy4 showcased.
By the way, the picture of the three Swedish pikes who were added to this thread, the largest one 19.9kg. All of them were catched and released just as the other twelve pikes above 15kg that were caught that year in Lödde å and for the record, the 19.9kg pike was the second largest one.
Tight lines, or as we say in Sweden, skitfiske.
