| Summary: | Molluscs are major aquaculture species worldwide. Molluscan aquaculture
accounts for approximately 27% of the total world aquaculture production.
The use and exchange of genetic resources have played an important role in
the development of molluscan aquaculture. The introduction and use of nonnative
species have been instrumental in oyster and scallop aquaculture; for
example, the Pacific oyster, translocated from Japan, supports major aquaculture
industries in many countries of North and South America, Europe, Asia
and Africa. Bay scallops introduced from the USA account for an annual production
of over 600 000 t in China. Non-native genetic materials have also
been used for the genetic improvement of native species through interspecific
and intraspecific hybridization. Unique genetic lines, such as disease-resistant
strains, have been developed through selective breeding in some molluscs,
although significantly more efforts are needed. Although the importance of
genetic resources is apparent, the identification, protection and utilization of
molluscan genetic resources remain a challenge. |
