The palm-size fish is called "chafak" or "chapak" and they're caught in the Caspian Sea, too. The price is rather high, which is approximately half of white fish. I was feeding my cats saying, "Just one!" until I found out almost half of the amount was gone. And it was after when I heard about the price.
Since the fish was small, I used scissors to cut open it from the belly. It was much easier to take away the externals that way than using a knife. I also found caviar in some of the fish but this time I decided to give them to my cats after boiling. For us, I fried them and cooked gatykliash.
Khalil likes dry, crispy deep-fried food. So I deep-fry fish for relatively long time. I do the same with potatoes, too. My preference used to be less dry but as I tried to adjust to his taste I got used to it. Exactly like kesmek (scorched rice), I've become addicted to the crisp.
