This here should be the second largest weighed polar bear that we have on record. The scientists captured the polar bear in Alaska: 110 stone (698.53 kg.....1540 lbs)
Q: How do you measure a 110-stone polar bear? A: Very carefully!
1. Alert to the intruders: The polar bear spots the research team
2. Bullseye: The team hit their target and the 110-stone polar bear falls to the ice
3. It's a knockout: A few minutes after being struck, the bear is unconscious
4. Lengthy: The researcher measures the length of the male bear
5. Hoisted: The bears is weighed with a special block and tackle

Sports Illustrated 1961 Text Extract:
This fierce new competition has led to some bitter rhubarbs, with Fitz making supreme decisions from his trophy-tilled penthouse in Manhattan. The most recent controversy involved a mammoth polar bear killed by Arthur Dubs of Medford, Ore. Mounted, the bear stands 11 feet 1½ inches, the tallest ever. But Fitz and the B&C Club take the position that bear records are meaningful only if based on the size of the skull. "The taxidermists seem to operate on the principle that what the hunter wants is altitude," Fitz grumbles, "and they mount these bears straight up in a position no polar bear has ever taken. Then they measure the height. And this can vary by as much as a foot or two for the same size skin." One can only pity poor Dubs. He may well have taken the biggest polar bear ever, but he can't even submit the skull for measurement because a piece of it was chipped off in the dressing operation. He is left with a gargantuan trophy totally lacking in official status.

POLAR BEARS IMMOBILIZATION. OUT OF 44 BEARS, 15 WERE 400+ KG, 9 WERE 500+ KG, AND 1 WAS 600+ KG. (DOES NOT STATE WHICH POPULATION)

Rarely does a polar bear pass 1300 pounds.

Rarely does a polar bear pass 1300 pounds. Right, except at Foxe Basin where they average around 590 kg (1300 lbs) shown at the original post.

What are they? Male polar bears mature sexually at six years old but they do not reach full size till 9 or 10 years old.

Reply #7, according to the right chart, for those 3 populations combined, the adult male polar bear averaged 426 kg (939 lbs) for 205 specimens.
For the solitary adult female, the average was 281 kg (619 lbs) for 70 specimens. Nice.

Thank you! Btw, I forgot the max size for the polar bear, which you haven't already posted:
Stenhouse & Nick (1985) 810 kg for one Canadian polar bear.

Summary: weights of males vary from 300 to 730 kg (660-1610 lbs), with some estimated up to 800 kg. Females weight 150 to about 400 kg (330-880 lbs)At least 3 populations average more than 1000 lbs:
Foxe Basin. Davis straight. Central Artic. I got a question, from where these measurements are from? Can you link me the study please?

Reduced body size and cub recruitment in polar bears associated with sea ice decline: Rates of reproduction and survival are dependent upon adequate body size and condition of individuals. Declines in size and condition have provided early indicators of population decline in polar bears (Ursus maritimus) near the southern extreme of their range. We tested whether patterns in body size, condition, and cub recruitment of polar bears in the southern Beaufort Sea of Alaska were related to the availability of preferred sea ice habitats and whether these measures and habitat availability exhibited trends over time, between 1982 and 2006. The mean skull size and body length of all polar bears over three years of age declined over time, corresponding with long-term declines in the spatial and temporal availability of sea ice habitat. Body size of young, growing bears declined over time and was smaller after years when sea ice availability was reduced. Reduced litter mass and numbers of yearlings per female following years with lower availability of optimal sea ice habitat, suggest reduced reproductive output and juvenile survival. These results, based on analysis of a long-term data set, suggest that declining sea ice is associated with nutritional limitations that reduced body size and reproduction in this population. pubmed.ncbi.nlm.nih.gov/20437962/
