Why is there no live hairtail?
Hairtail generally lives in a place with a water depth of less than 50 meters, and its living conditions are poor. However, after the hairtail is caught, it can't adapt to the pressure of the sea surface in a short time, so the swim bladder that controls the ups and downs of the hairtail will rupture, resulting in the death of the hairtail within three hours after it comes out of the water.
Therefore, the caught hairtail will generally be frozen and preserved immediately after arriving in Hong Kong.
