The biggest was a 50cm European Bass with very light material in the Ardennes near Bastogne. In Sweden I did catch but not land a pike of about 3,5 feet with the same light rod, it killed my underline just before I could grab its gill. Thought the rod might break sooner though..
European Perch I mean, in The Netherlands we call it Baars which sort of sounds like Bass. My bad Was a fat one too, around 2,3 kilos according to dingy aquipment. I'll try and post a picture here soon.
Haven't been fishing for long, so the biggest fish I've caught is a warmouth sunfish the size of my face, or a 10" croaker- depends on if you count longest or heaviest as biggest.
On the other hand, the smallest I've caught (yes, hook and line) is a 3/4" gambusia. There are some VERY small hooks. I've also caught a 1.5" baby bass off a dock.
