Asian hard clam, Meretrix lusoria (Bivalvia: Veneridae), is
an abundant bivalve in East and Southeast Asia (Yoosukh &
Matsukuma, 2001). This clam has served as an important shellfish
distributed around Japan, Korea and China and its cultivation has
been growing (Chung, 2007). Nevertheless, this hard clam is not
popular for consumption in Thailand, owing to a high amount of
mucus and a tough texture. Due to the low market value associated
with the low demand, it has been used as an alternative source of
baby clam (Cardiidae) in the canned seafood industry, and as raw
material in shrimp feed processing to reduce the shrimp culture
cost (Yadfon Association., 2012)
