Size is gonna depend on food, location and predators.. Beaver grow their entire lives .. When I first started beaver trapping around 25 years ago no one had beaver trapped in our area for generations.. Beaver were relatively new to our environment.Maybe been there 15 years The grew, feed on corn and breed with no check what so ever.. By the time I started trapping them they were everywhere.. I had the game Warden and district biologist calling me non stop...
Im not kidding at all.. I caught 60 pound beaver almost every where I trapped.. Weighed 60 pound beaver.. First two seasons I caught several over 70.. Big beaver were all over because they had more corn than they could eat and no check, no trappers and no predators..
That 94 pound beaver came from a corn field, where she had dug a hole so big the farmers tractor dropped 4' down in a hole more than 20' from the waters edge...

Not everything is about money Swampy.
Just think of how famous one could be if they caught a world record anything,lol.

I caught a 72 pounder one year out of a pond for a church camp. Tagged my cats that year at the state office at Pomona reservoir. Told the biologist about it and he said might be a record. I had already skinned it but he got some stuff out of a file cabinet. said it was 120 something. I dont know if he meant state or national. Was at least 20 years ago. They can get that big apparently.

You want to be famous Boco?

How famous is a world record beaver catcher gonna be?

Lol , I was thinking the same thing. Someone on this site might remember you a year later , but probably not two .

Just look at the expression on that guys face and tell me this is a serious picture. No way.

HA HA HA!!! And some change.

I've read that before that supposedly beaver continue to grow all their lives. Not sure that's true. When their health declines they may actually decrease in weight as they got no fat...just skinny and lean.

A transplant beaver was caught in Oregon with ear tag and documented 15 years age. Sure wasn't no 80 lb beaver.

That pic is JByrded .
Easy to see.

Biggest I have gotten is 72# and I was using a 40# cement block for a drowning weight which he had drug up on the dam and was sitting there when I showed up. Our local game warden who was also a state trapper got one down in southeastern NE at a city park on ADC work that weigh in at 105# but that was 50+ years ago.

You guys are just jealous that you never caught one that big.

My first few beaver were 55+ the heaviest being 62. I thought this was normal. The next 30-45 lbers I thought were kits….hahaha
