[5] In Japan, large numbers of A. pectinata were traditionally found off the southwestern coast, with commercial activity centered around Kyushu Island.

[2] A suspension study of A. pectinata showed that in artificial habitats, gonad development occurred at the same time for both male and female pen shells and corresponded to warming water temperatures and increased food availability.

[6] A. pectinata has a pelagic larval phase that lasts about 30 days and mean fecundities of 29 million eggs per year, which suggests high dispersal potential.

[3] A. pectinata population has decreased rapidly since 1990 as a result of overfishing, habitat loss from coastal development, pollution, etc.

[5] It is a popular food source and is commercially important to a number of countries which makes it a great interest to fisheries.

[5] A. pectinata mortality events in 2003 and 2004 reveal that the southwestern Japan population suffered from necrosis in their gills and kidneys not caused by known pathogenic agents.

In an effort to conserve the shellfish species, microsatellite markers have been used to access the genetic variability and differentiation of A.
