Stock enhancement

Grafting experiments where an induced scion (sunflower or a day-neutral- or short-day-induced Jerusalem artichoke) is grafted on a short-day stock enhancing tuberization (Daniel, 1934 Schiebe and Muller, 1955 Sibija, 1937 van de Sande Bakhuyzen and Wittenrood, 1951 Wagner, 1932). 

R. esculentum was selected as the species to be studied at the Liaoning Ocean and Fisheries Science Research Institute of China, cultured, and released for commercial harvest (Dong et aL, 2009). The technology of artificial breeding, pond culture, and stock enhancement in nature were developed along the coast of northern China. 

Thus, abundant juvenile jellyfish can be obtained in a short time in the correct culture conditions, and the techniques were applied to large-scale production for stock enhancement (Dong et al, 2009). In 2005, the total volume of rearing tanks for juvenile R. esculentum was about 30000-40000 m in Liaoning Province. In recent years, over 500 million juvenile jellyfish were cultivated in breeding centres there annually.
