Since 1997, scientists at the Yellow Sea Fisheries Research Institute (YSFRI) have been working to breed a new variety of Penaeus chinensis, commonly called the "fleshy shrimp". In 2004, after seven generations of selection, they produced a fast-growing strain of the species called "Huanghai No. 1 Line".

Funded by the Ministry of Agriculture, YSFRI recently built a new Genetic and Breeding Center for Mariculture in Qingdao. Fully operational since the spring of 2006, the facility includes a 2,500-square-meter greenhouse with 300, 200-liter fiberglass tanks and 50, 10-to-40-cubic-meter cement tanks for larval culture.

In 2006, 180 full-sib and half-sib lines of P. chinensis were produced and studies were conducted on growth rate and disease resistance.

YSFRI has made significant efforts to popularize the new Huanghai No. 1 Line in the northern provinces of Shandong, Jiangsu and Hebei, and various culture demonstration projects have been carried out.

Over 10,000 selected spawners, overwintered in indoor tanks, were distributed in early March 2006 to several hatcheries for larval production. In Hebei Province, a hatchery produced 100 million postlarvae using 1,000 spawners, while at the Changyi hatchery in Shandong Province, 150 million postlarvae were produced from 1,600 spawners. In 2006, the total pond area stocked with the Huanghai No. 1 Line was over 6,500 hectares. To date, data on growout parameters are normal, and a good harvest is expected.
