Amino acid and biochemical composition of Banded Carpet Shell (Polititapes rhomboides, Pennant, 1777), collected from the Çardak Lagoon, Turkey

Abstract

Between January and December 2019, banded carpet shell (Polititapes rhomboides, Pennant 1777) were gathered from Çardak Lagoon (Çanakkale Strait). The length value was found to range from 32.92 to 36.37 mm, weight between 7.90 and 11.75 g, condition index from 4.44 to 8.70, and meat yield was found to be ranging from 11.95% to 24.95%. Negative allometry was determined in the W/L relationship of P. rhomboides. The main meat component of P. rhomboides was moisture (54.70-65.57%) and protein (52.89-62.10%) with the other components being carbohydrate (10.95-21.30%), lipid (12.79-17.18%) and ash (7.69-19.93%). The correlation between moisture and carbohydrate was positive, whereas the correlation between moisture and protein was negative (p<0.05). The present study not only informs us on composition but also recommends consumption of the species since it is easier to market and consume. Arginine amino acid was found to be the highest in quantity, which was followed by glutamic acid, serine, methionine, alanine, and aspartic acid.
