Its too late..
They couldnt really save him, he was suffering too much.. He needed a mother whale to feed him.. So how do you think they were supposed to do that? Do you see anyone with huge whale boobs?
If they let him swim out to sea by himself, he would have suffered more. But they've put him out of suffering now..
They couldnt transfer him to a zoo or whatnot, because he might have diseases.. And if he did, he would kill all the other animals that share the water with him..
Japanese whale killing is a different story mate. They choose to slaughter healthy whales, the whales they slaughter arent sick at all. They hunt them! .. Collin just happened to wander around where he shouldnt have, if he was out in the sea, then the public wouldnt know about him. It happens alot in the wild.. He was suffering, but now he wont be suffering anymore.
I'm not being negative here.. Its just the aweful truth. There really wasnt anything they could do for Collin, so they had to put him out of misery...He coudlnt even breathe properly anymore..
PS. How could he have found his mother when its been a week? She has been swimming for a week, so she is a week away from here. How is the poor baby whale going to catch up before he dies? Thats impossible, unless another mother whale adopts him... but she would probably only do that if she lost her baby as well.
He was sick, thats probably why he was abandoned.. The mother saved the pod whales Collin was in from getting sick aswell
EDIT: Collin is at a stage where he cant eat yet, he is still on his mothers milk .So getting a truck load of krill to him would be pointless, he wouldnt eat it at all. If he could eat, then he would have been fine..
And yeah, dont nurse a fox back to health, those are introduced animals, not native.. No one would be thankful
