2013년 8월, 9월 동해 남부연안 살오징어 유생 분포 = Distribution of the Common Squid Todarodes pacificus Paralavae in the Southern Coastal Waters in the East Sea in August and September 2013

다국어 초록 (Multilingual Abstract)

Paralarvae of the common squid, Todarodes pacificus Steenstrup were sampled with the bongo net (diameter: 60 cm, mesh: $333{\mu}m$) by using oblique tow method with the oceanographic research vessel (Tamgu 12) at 21 stations along the southwestern coastal waters of the East Sea in August and September, 2013. Paralarvae were collected 16 ind./$10m^3$ in August and 7 ind./$10m^3$ in September at approximately, and bottom depth was from 70 m to 500 m. Mantle length of paralarvae was from 1.7 to 6.0 mm. Paralavae were distributed mainly in offshore stations in August and near by Cape Janggi in September. Optimum embryo survival temperature ($18-24^{\circ}C$) was formed shallower than 35 m depth for almost stations where paralarvae were existed, and survival temperature ($15-24^{\circ}C$) for embryo stage was located shallower than 75 m.
