Buying fish
How to choose the right fish?
If the fish is sold whole, you can see if it has scales and fins.
Fillets, pieces of fish or minced meat should only be purchased in a safe place, from a vendor who only sells kosher fish.
Packaged fish products must bear the kosher mark. Kosher fish roe - kosher. The roe of non-kasher fish is non-kasher. So black caviar is forbidden to us, and red caviar is allowed.
