Live Sea Urchin

Grading Factors

Quality assessment for live sea urchin considers Spine condition, Body weight and fullness, and Oral area condition.

• Spine condition

  The firmness and color of the spines indicate the animal's health and vitality, which are essential for maintaining roe quality until consumption.

• Body weight and fullness

  The weight and fullness of the animal correlate with the size and quality of the gonads, which are the primary edible part.

• Oral area condition

  The condition of the oral area, including its firmness and color, reflects the overall health of the urchin.

Common Defects

Recorded defects for live sea urchin include Spine damage, Oral area deterioration, and Low body weight.

• Spine damage

  Limp or broken spines indicate stress, poor handling, or the onset of death, which can lead to rapid quality loss.

• Oral area deterioration

  A soft or sunken oral area suggests the animal is weak or dying, which can result in poor roe quality.

• Low body weight

  A light or empty body weight relative to size indicates low gonad yield, reducing the economic value.
