Sänas is perhaps a cheap fish

I would really like to eat Estonian fish myself, but all the bigger fish (that is, not squid, herring and kilu) are so expensive per kilo that I would rather buy something other than them. Now I read that the price of a kilo of seinase at wholesalers is 30 cents.

How would I be able to buy this fish even ten times more expensive?

I don’t have time to go fishing and I live in the countryside.
