Perhaps, probably some kind of crocodile farm. The only thing I don't understand is what's the point of running around with a shovel and chasing them into the water.Maybe it is a her those are the babies ?
The original video is probably hanging around somewhere on YouTube, and I only saw a repost on a Russian-language resource, so I can't ask directly. It doesn't matter, I'm not going to breed crocodiles here

YouTube doesn't work in Russia, so I don't have the technical ability to find the original video and ask its author why he's chasing crocodiles.

Well, it doesn't matter.
