Some characteristics of growth performance, nutrition, and biochemical composition of asiatic hard clams Meretrix meretrix (Linnaeus, 1758) distributed in Tam giang – Cau hai Lagoon, Thua Thien Hue province
Summary: Meretrix meretrix (Linnaeus, 1758) was collected in Tam Giang – Cau Hai lagoon to analyse the growth, nutritional characteristics and biochemical composition of the soft body of the clams. The age, the relationship betweenthe dimensions (length, height, and width) and weight (401 samples), and the food composition in the stomach, intestine, and syphon tube were analysed. The results showed that the age structure of Meretrix meretrix was simple, ranging from 0+ to 4+ years old, in which group 0+ was the most abundant (53.37 %), corresponding to the body weight ranging from 1.1 to 18.9 g/clam. The equations were found as follows: W = 0,0004×L 2,8809 (R² = 0,98 ); W = 0,0005×H2,9504 (R² = 0,988 ), and W = 0,0019×D2,9462 (R² = 0,9833). The equation for the relationship between the weight of the soft body and the whole weight was Wfm = 0,1 8×W + 0,9596. The food found in the stomach, intestine and syphon was mainly the organic matter (92,5 %), and the rest was phytoplankton (7,5 %). The soft body part of the clams contained 10.62 % protein, 1.70 % lipid, and 4.73 % carbohydrate.
