Ayer Fish (Sperata aor) – Cleaned & Ready-to-Cook
The Ayer (or Aaur) is a premium freshwater giant, often called the "Long-whiskered Catfish." It is considered one of the most elite fishes in Bengali cuisine, second only to the Hilsa and Rohu in status, but superior to many in terms of its meaty, boneless quality.
