Conch is mainly produced in coastal shallow sea bottom and spread all over the world. Foreign countries are distributed in the East African coast, Caroline Islands, Samoa Islands, Hawaii Islands, southern Japan and so on. In China, it is distributed in Taiwan Province Province and Xisha Islands, and produced in Little Ryukyu, southern Taiwan Province Province and South China Sea.

There are abundant conch resources in the central and western parts of the South Yellow Sea, with the most fragrant snails, followed by red snails; Snails are widely distributed in the north, mostly at 34 degrees north latitude. The sea area outside the 30-meter isobath north of the line likes to inhabit the muddy seabed with moderate hardness; The distribution range of red snail is narrow shallow water area. Most of them are dragged on the hard and muddy seabed between the closed fishing line and the 40-meter isobath.

The culture method of conch:

Shellfish such as conch are oviparous or viviparous animals (it is a transitional species between oviparous and viviparous, and some kinds of sharks are oviparous). The production period of conch is probably May-August. During this period, the water temperature in this sea area is high, which is suitable for the life and reproduction of conch.

Some species of conch ovulate and ejaculate collectively mainly in the sea. After fertilization, the fertilized egg floats in the water like plankton, attaches to the reef, and waits for hatching in the gap of the reef. Some species hatch themselves in the body, similar to the reproduction of snails.
