Abstract:

The limpet samples (Nacella concinna) were collected in the intertidal zone of Great Wall Bay, near the Great Wall Station, Antarctica, and analyzed by conventional biochemical methods. The result showed that the content of crude protein, lipid and ashes in the soft part (dry basis) was 58.39%, 11.54% and 9.97%, respectively. The content of the amino acids to the total dry weight of the soft part was 27.51%, in which the essential amino acids was 11.25%, accounting for 40.89 % of total amino acids. The EAAI was 45.79 , and the first limited amino acid was Val as compared with the FAO/WHO suggested level (1973). The unsaturated fatty acids constituted 21.20% of the total fatty acids. There was a high content of mineral in the soft parts of Nacella concinna. In a word, as a prey, Nacella concinna could provide high quality food for gull (Larus marinus) and penguin.
