Sea Urchin Farming Industry

Sea Urchin Farming Industry

Sea urchin farming is a new but rapidly growing industry. Sea urchins are small, globular animals with numerous calcareous spines on their body surface. The primary use of the sea urchin is for the highly valued edible roe (eggs) which are considered a delicacy in Japan and other parts of Asia. Several species of sea urchins have been cultured.

The body of the sea urchin is typically globular with numerous calcareous spines on its surface. These spines are not poisonous and they are used in locomotion, defense and burrowing activities. The mouth is situated on the ventral side at the center, surrounded by five equally spaced teeth plates. The food is ingested through an opening called the Aristotle's lantern present at the center of these teeth plates.

The primary use of the sea urchin is for edible roe or eggs. These roe are considered a delicacy in Japan and other parts of Asia and fetch premium prices in international markets. The gonads or eggs have been rated as one of the most expensive seafood items in the world market today.

The sea urchin farming industry is a recent arrival to the diversification of aquaculture. While other marine species, such as salmon and shrimp, have been grown in captivity for many years, the idea of farming sea urchins only recently entered the realm of commercial viability.

The sea urchin's edible reproductive organ, known as its "roe", is considered a delicacy in some parts of the world, making it a valuable commodity. The largest markets are in Japan and the United States.
