This video is actually very educational, especially for those who have never heard of the Empurau fish (or Unforgettable in Chinese), from Sibu, Sarawak, which I think is probably the world most expensive, at RM800/kg (or almost US$270/kg). Anyone knew of any other fish that is costing more?
This video was made by a Taiwanese travel channel 世界第一等. It shows how the fish was caught and finally how it was being cooked.
I just realised that this fish loves to eat seed and the scale is also edible! This reminded me of my childhood days when we use rubber seed to catch cat fish in the wild.
