Apparently a “wildlife technician” with the Alaska Department of Fish and Game is looking into the effect of Tasers on bears and moose:

Lewis said he first became interested in the subject in June of 2005 when an Alaska State Trooper asked for his assistance with an ornery cow moose.

“I had an epiphany while being chased by an angry moose,” Lewis said.

The cow moose was upset because her two calves were trapped in an open four-foot deep basement foundation at a home construction site. She would not leave the area, even when Lewis tried using noisemakers and rubber shotgun ammunition.
Finally, Lewis said he tried to drop a ramp down into the pit so the calves would be able to walk out on their own. But when he approached the calves, the cow moose charged him, jumping into the foundation, across it and back out.
It then chased Lewis and the trooper three times around the patrol car.

Both men were armed but rather than shooting the moose, Lewis said the trooper used his Taser to shoot at the moose across the hood of the patrol car. The Taser’s barbed, conductive leads hit the moose in the left front shoulder. Stunned and immobilized, the moose hit the ground immediately. The leads pulled free as the moose fell and it quickly ran off into the woods, staying there long enough for Lewis to extract the calves from the basement and for both Lewis and the trooper to retreat safely to the patrol car.

It worked so well on the moose, Lewis began wondering if Tasers might be used in similar circumstances with moose, and in other situations, with bears or other animals.

Working with Lohuis and Beckmen, Lewis studied the effects of Tasers on about a half dozen captive moose at the Moose Research Center in Soldotna. He is also working with Taser International to improve a design of the non-lethal weapon for use on wildlife.

To evaluate how the Tasers affected the moose, Beckmen took blood samples and studied stress in the animals before and after they were hit with Tasers.

“It’s not without cost to the animal,” Lohuis said. “But that stress doesn’t appear to be long-term. Our blood samples indicated the moose started to return to normal within 20 to 30 minutes compared to the 24-48 hours it takes a moose to recover from being drugged.”

The animals also did not react aggressively after being hit by Tasers. Instead, they fled.

“I have worked with Gorillas as a zookeeper while in my twenties and they are my favorite animal that I have ever worked closely with. I am gonna go ahead and list a few facts, thoughts and opinions for those of you that aren’t familiar with the species itself, or how a zoo operates in emergency situations. Now Gorillas are considered ‘gentle giants’ at least when compared with their more aggressive cousins the chimpanzee, but a 400+ pound male in his prime is as strong as roughly 10 adult humans. What can you bench press? OK, now multiply that number by ten. An adult male silverback gorilla has one job, to protect his group. He does this by bluffing or intimidating anything that he feels threatened by. Gorillas are considered a Class 1 mammal, the most dangerous class of mammals in the animal kingdom, again, merely due to their size and strength. They are grouped in with other apes, tigers, lions, bears, etc. While working in an AZA accredited zoo with Apes, keepers DO NOT work in contact with them. Meaning they do NOT go in with these animals. There is always a welded mesh barrier between the animal and the humans. In more recent decades, zoos have begun to redesign enclosures, removing all obvious caging and attempting to create a seamless view of the animals for the visitor to enjoy watching animals in a more natural looking habitat. this is great until little children begin falling into exhibits which of course can happen to anyone, especially in a crowded zoo-like setting. I have watched this video over again, and with the silverback’s postering, and tight lips, it’s pretty much the stuff of any keeper’s nightmares, and I have had MANY while working with them. This job is not for the complacent.

Gorillas are kind, curious, and sometimes silly, but they are also very large, very strong animals. I always brought my OCD to work with me. checking and rechecking locks to make sure my animals and I remained separated before entering to clean. I keep hearing that the Gorilla was trying to protect the boy. I do not find this to be true. Harambe reaches for the boys hands and arms, but only to position the child better for his own displaying purposes. Males do very elaborate displays when highly agitated, slamming and dragging things about. Typically they would drag large branches, barrels and heavy weighted balls around to make as much noise as possible. Not in an effort to hurt anyone or anything (usually) but just to intimidate. It was clear to me that he was reacting to the screams coming from the gathering crowd. Harambe was most likely not going to separate himself from that child without seriously hurting him first (again due to mere size and strength, not malicious intent) Why didn’t they use treats? well, they attempted to call them off exhibit (which animals hate), the females in the group came in, but Harambe did not. What better treat for a captive animal than a real live kid! They didn’t use Tranquilizers for a few reasons, A. Harambe would’ve taken too long to become immobilized, and could have really injured the child in the process as the drugs used may not work quickly enough depending on the stress of the situation and the dose B. Harambe would’ve have drowned in the moat if immobilized in the water, and possibly fallen on the boy trapping him and drowning him as well. Many zoos have the protocol to call on their expertly trained dart team in the event of an animal escape or in the event that a human is trapped with a dangerous animal. They will evaluate the scene as quickly and as safely as possible, and will make the most informed decision as how they will handle the animal.”
