You can even create an artificial trout river through your living room but that might cost a lot. If you are Rockefeller then it's nothing but if not - do you need it? Will it be a smart way of spending money?
The same about these highly powerful pumps. Probably they work as designed but cost a lot... You said that you might create that pond by yourself - it means you aren't Rockefeller
By the way, that salmon isn't a carp or a pike. It simply might dislike it's new home and you can have your money wasted.
Maybe forget about that salmon and better look at other options.
