Abstract: China has more than 1 512 300 hm of coastal mud. The mudflat mollusks as the dominant species in the
intertidal zone possess many advantages, including fast growth, strong adaptability and environmental friendliness.
Therefore, the development of mudflat mollusk aquaculture has great prospects, superior conditions and consider-
able potential. Zhejiang province has a long history of mudflat mollusk aquaculture and developed distinct charac-
teristics and advantages in the aspects of cultivation technology and model, artificial spat collection and seed
breeding, large-scale breeding and breeding of new varieties. However, it also faces severe challenges in the tech-
nology innovations and development of the mollusk seed industry. This paper reviewed the history and current
status of mudflat mollusk aquaculture industry, seed production technology, germplasm innovation and variety
improvement in Zhejiang province. Arrangement of the topics around the highly efficient and accurate evaluation
of economic traits, breeding technology innovation, breeding of new varieties with high quality and stress resist-
ance, key technologies and equipment research of efficient propagation, and seed industry system construction
were discussed. The key tasks of new varieties breeding and seed industry development of Zhejiang mudflat mol-
lusk in the future, especially in the 14th Five-Year Plan period are proposed.
Key words: mudflat mollusks; seed industry; germplasm resources; scientific and technological innovation; vari-
ety creation
