Great Find; I have the link for the first episode of "The Great Bear Stakeout". I've watched it and at Minute 54:30 the scene of Van killing the female bear everyone was looking for starts; that gave me goosebumps...

King KodiakThat female he killed was larger than his mate "Alice" who was a fully grown female herself. Exact weights are unknown unfortunately.

Bear biologists must be really good at estimating the weight of a bear. When a bear is darted with a drug, the amount must be very near precise. Too much can kill the bear. Too little endangers both the bear and the biologists. So, when an experienced bear biologist gives an estimation of a bear's weight; his estimation is very near accurate.

Capture Methods: Most bear captures are done by helicopter dmting. In heavily timbered coastal areas Aldrich foot snares are often employed. Barrel or culvert traps are utilized to capture black bears and occasionally brown bears when access permits their employment. Black bears are also recaptured by locating and immobilizing them in their dens. Soon after coming out of their dens, newborn cubs of all three species are caught by hand.
Chemical Immobilization:
1. Tiletmnine/zolazepam (TelazolĀ®): 3 - 5mg/lb.
The lower dose is used on large bears, older bears, bears in poor condition, or bears just out of their dens. The higher dose is recommended on small bears, young bears, bears in " good condition, or bears prior to denning. This is the drug combination of choice for helicopter dmting and most other bear handling situations. The above dosage range provides 45 - 75 minutes of safe handling time. Supplemental doses of 1.5 - 2.0mg/lb will provide an additional 45 - 60 minutes of light anesthesia. Behavimal responses observed during induction in the order they appear are: disoriented gait, high stepping, loss of use ofhind legs, licking lips, loss of use of forelegs, loss ofhead and neck movement, nystagmus, and loss of tongue movement.
Bears with only tongue and minor head movements are safe to approach and work on. Those with excessive head and neck or any foreleg movement are not safe and should be given more time or a supplemental dose. Most bears recover in 1.5 - 2.5 hoUTs, bllt an occasional bear may be immobilized for up to 4 hours. There is no reversal agent for this drug combination.
2. Ketmnine 3.0- 5.5mg/lb and xylazine 1.5- 3.0mg/lb. This drug combination works well in bears :s; 100 lbs., but its use in larger bears is limited to the commercially available drug concentration of each and the resulting volume of drug required. Ketmnine is very short acting reaching peak effect in 20 - 25 minutes and then is rapidly metabolized within 30- 45 minutes post injection. Xylazine provides approximately 2 hours of sedation but the analgesia dinllnishes after 30 minutes. Therefore, any handling time with this drug combination beyond 30 minutes will likely require supplemental dosing ofketanline at 1- 2mg/lb.
Additional Information: 1. Most bear capture work is done in late spring or early summer when bears are thin and D :Y. to 1 Yz inch needles are used depending on species and age of bears being darted. Occasionally bears are captured in the fall when they may have 2\1, to 4 inches of subcutaneous fat located over the lower back, rump, and upper hind legs. Instead of using a longer needle that could penetrate the thorax or abdomen inflicting trauma to the lungs or other internal organs, when dmting fall bears I recommend using 1 \1, inch needles and targeting the shoulder/base ofneck area.

I thought this was interesting. "lower dose for larger Bears, larger dose for smaller Bears". I copied this from a PDF file I found online and it pertains to Alaska.

I'm not even going to pretend I understand any of this. But, fact: the biologist who darts a bear must know how to estimate the bear's weight, age, and general health condition.

Yeah I don't quite understand their logic. 3-5 mg /lb of bodyweight is used. the smaller dosage 3mg is used on larger and or older Bears, Bears in poor condition, while the larger dose 5mg. is used on smaller younger Bears, Bears in good condition or prior to denning. I would have guess the opposite but.... I'm not a veterinarian. Maybe it has something to do with age?? I do know with humans and dogs that anesthesia is more risky the older you are. I do know this is true for sure with dogs. My 14 year old dog who has heart disease is not a candidate for anesthesia I was told not only because of his condition but his age.

Doug Peacock told of a Yellowstone grizzly that was given too little tranc. He ran until the drug took effect. Where he passed out, there was a puddle of water. The bear passed out and ( as fate will have it ) his nose was in that one puddle of water. The bear drowned. There are other stories too with sad endings. So, the biologists must take great care in the dosage of drug they dart a bear with.

I believe the cub will get back in the wild successfully. Brown bears are adaptable animals.
