Theres an issue for me in Singleplayer where they teleport away never to be found again if their close to being knocked out using the Bloodstalker and Rocket Launcher method. The easiest way for me is to lure it near the land and fire a Cannon Shell from a mek. People say to use the Skiff and Cannon method but it might teleport away aswell.

If you fall you will be teleported back to the nearest land mass. Just FYI. Used mek and kod 3 each with 1 shot to the head. Highest level 100 lowest level 25. Use hazmat suit to be able to move around in radiation and not burn to death. Bring med brews and stew to counter freezing.

You can use canon stryder for Knock Out

Become a space pirate load a skiff with cannons aim for the head and knock it out easier with 2-4 people.

DONT USE HIGH LEVEL MEKS TO TAME THIS Because when you shoot at it with the missle thing you'd just killed it

The best way to tame it is with a skiff armed with 2 Canon at the front of it.

Shoot one Canon first, wait for the whale to come to you, then shoot both Canon : it sleeps

You can find astrocetus in the space biome of gen 2. From my experience they seem to spawn more during ambergris space (although I have no actual evidence to back this up). If you manage to find a good one it's pretty easy to trap them in the narrow area of the space bridges with a few behemoth gates.

Get a mek,put the rocket launcher attachment on it,then shoot at its head

Because of no Tek Skiff on Gen 2 without unlocking it via Gen 1, I recommend using a Tek Stryder with a shield and a gun attachment, this way you can aim your canon effectively without much movement from the Stryder.

The shield (preferably the front facing one) will be a good defence against hostiles and you can pick them off.

Use extraordinary kibble. Exceptional kibble isn't good enough.

You can tame them pretty easily with rockets by shooting it to head

Just put some buildings and when it attacks the buildings then build a canon and point to its head and that’s the most easy way to sleep it

Cheat Summontamed spacewhale_character_bp_c

Did a test tame on a level 95 on official. Not even 40 rockets knocked it out. Shot it in the head, and by head i mean the very front of its face everytime, about 8 seconds between shots to align myself and aim. Didn't KO. The amount of rockets is wrong.

Can be knocked out with a metal cannon but the taming effectiveness is low

You can use a quetzal on genesis part 2 to tame a space whale. So you don’t need to make a tek hoverskiv.

Just grapple to its head and extend the line. It will push you back far enough to fire rockets and not get hit.

Taming glitches? Only went up one level for 2 whales with mutton

Until fixed, every level only requires 7 extraordinary kibble

Tek skiff+ Rock turret= tame space whale
