The short answer is no !!
In fact winter is better for some types of fishing...Large pelagics like cool water, and so they come closer to land in the winter.
Search the Forum for ice fishing They basically drill or make a hole in the ice and catch fish...
It has been around minus 3 to minus 4 here for the past week or so...It is a long weekend...But on Tuesday, I am going to the "Bidgie" chasing cod. I might catch one, or I might not...No different to the summer at 40+ in the shade...Might catch one or might not.
It is not about the catching...It is all about the fishing
