Redfin Puffer Fish

Redfin Puffer Fish

　　The artificial breeding base for redfin puffer fish is situated at the Han'guu Marine and Freshwater Hatchery Center in the Hangu District of Tianjin. Endowed with unique natural resources, robust scientific and technological expertise, advanced management practices, and a pioneering drive, the redfin puffer fish breeding initiative has been listed as one of Tianjin’s municipal-level key agricultural industrialization projects. It has been identified by the Tianjin Science and Technology Commission as a premium product to be recommended to the nation, and has been awarded the First Prize for Scientific and Technological Achievements by the city.

The redfin puffer fish is a toxic yet economically valuable species that has not yet been widely developed or utilized in China. However, countries such as Japan began utilizing it as early as the 1980s, achieving advanced levels in both artificial breeding and adult fish reproduction. The redfin puffer fish offers high nutritional value and is extensively used in the production of valuable medicinal products. Its liver and blood toxins are widely extracted for various applications, yielding substantial economic benefits. There is strong demand in international markets, and in recent years, dishes featuring redfin puffer fish have become common on the menus of high-end hotels and restaurants in major Chinese cities.

Since 1995, the Han'guu Marine and Freshwater Hatchery Center has introduced fully fertilized redfin puffer fish eggs to conduct hatching experiments. The successful overwintering of juveniles and cultivation of adult fish were achieved. From 1996 to 1997, large-scale breeding was carried out, with all products sold overseas, generating considerable economic returns. In 1998, numerous domestic and international merchants contacted the center via phone, mail, and in person to discuss the purchase and sale of redfin puffer fish, indicating very promising prospects for expanding its production.

　　The Han'guu Marine and Freshwater Hatchery Center continues to expand its production capacity. To date, it can breed 15 to 20 million redfin puffer fish fry annually and produce over 10 million adult fish, each weighing 450 to 500 grams or more. Between 1999 and 2000, the center plans to increase its breeding capacity to over 100 million fish, with adult fish production exceeding 500 million.
