Characteristic of Morphometric and Growth of Anadara pilula

One of species in genus Anadara which is used as food alternative resources is Anadara pilula (Reeve, 1843). The knowledge of this species is very limited because it has not been well studied than A. granosa (Linnaeus, 1758). This research aims to analyse characteristic of morphometric, biometric and growth of A. pilula from Tegal waters. Measurement of length, thick and height of shells as well as total weight of cockle were measured from December 2009 to February 2010. The result showed that there was strong correlation ((r≥0,8) in the dimensions of the cockle shells, the growth of shells length was more dominant than thick and height. This phenomenon cause the form of A. pilula is nearly circular. There were relationship between dimensions of cockle shells with total weight (alometri negative, b 3) which was meant that growth of cockle shells is faster than weight and influenced the condition factor of cockles. This also can be used in determining the best of harvest size.
