A difficult solo tame: have 10-20 narcotics in small stacks ready to go in your inventory, take out something that effectively collects prime. Collect said prime then walk along coasts or waterways until the compy's find you. Knock them out right next to your creature, dose up with a couple narcotics then move the prime as fast as possible from creature to compy. Using 1-4 narcotics in between moving items
It's not a very good tame when you first get ark, it needs rare meats and you have to watch its torpor. But, if you can get your hands on a lot of narcs and prime fish meat, you can tame a whole lot of these.
