For knockout most of the time unless your are taming a low level you MUST use darts the arrows will practically 80-90% die so you must use darts. Also when looking for one you should look either at cold places or in redwood forests. Cold areas have some but redwood forests will have so so many with plenty their you can find the perfect level that you want to tame and that you can handle.
These things are absolute beasts, they do insane damage, grind like a boss, and gain momentum while sprinting, to tame these, get a mount which allows rider weaponry and invest decent amount of health in it. Then let it aggro on you and start tranquilizing them ( rifle advised since x-bow may kill it ).
Its torpor run isn't that annoying so just knock it, feed it, then wreck the island's almost every bit( gigas and titans are exceptions ). Up if this helped.
To make honey last practically forever, make a fishing rod and equip honey, that is about to spoil, to the fishing rod, then un-equip it. It should refresh the spoil timer. Does not work with leech blood. Tested on PS4.
