Yes those walleyes were caught while musky fishing at speeds considered too fast for walleyes and on lures considered much too large for walleyes.At times high speed can trigger just about all predators and i also get some large bass(4lbs+) at times too as well as pike.I do troll a lot of body baits but not exclusively.As far as the world record is concerned,i believe that the relatively recent canadian record(1988),is the world record.At 56.5" x 30.5" and 65lbs it is much larger than any of those supposed world records from the 30's,40's and 50's.I was discovered that a lot of those 60 lbs+ fish were actually 45-50lbs and padded with lead weight .While still large fish ,they were not world records.Their dimensions were also exaggerated as can be easily seen in photos.I saw a picture of a claimed 64 inch fish in which the guys wife was standing behind the fish and it was shorter than her.Her known height was 5' 2" (62"),thus making the fish was mush shorter than her.These days it seems a lot of people like too exaggerate girths of fish.Any musky with a girth of 24" or more is very fat and not very common and i've seen a lot of thin to average built fish with girth claims of 25 to 30 inches!Please. A 60lbs fish will need to be a least 54" depending on girth. 54"x30.5" / 56"x30" / 58"x29.5" or 60"x29" is the min. of what it would take to actually crack 60 lbs. A recent Georgian bay fish was caught an kept and at 55.5" x 31.5" it weighed 61.5 lbs. The fish in my avatar has a 25.5" girth so that should give you a pretty good idea of how fat a fish has to look to have a girth over 24".
