Identification and Quantification in Food

The first occurrence of a giant squid, Architeuthis sp. (one specimen), and the oarfish, Regalecus russellii (two specimens) in the East Sea were reported based on specimens collected in January and February 2010. The giant squid (Architeuthis sp.) stranded at Pohang in Jan. 2010 was female, 175 cm in mantle length (ML), 506 cm in tentacle length (TL), and 33.9% FL/ML, it contained common squid beaks. Both stranded oarfish (Regalecus russellii) at Uljin (Jan. 2010) and Yeongdeok (Feb. 2010) were male, with total weigths (TW) of 18,506 and 21,703 g and total lengths (TL) of 3,850 and 3,670 mm, respectively. The stomach of the first was empty, while that of the second was filled with euphausiids. In the East Sea, giant squid have been stranded 14 times in five areas, while 17 oarfish have been stranded in nine areas. Since 1990, the two species have been found most often at Pohang.
