Distribution of Common Squid, Todarodes pacificus , Paralarvae in the Yellow Sea in Spring and Autumn, 2013 - 2015
Abstract
Paralarvae of the common squid, Todarodes pacificus, were sampled with the bongo net (diameter: 60 cm, mesh: 333 μm) with a research vessel (Tamgu 20) at 18 stations along the coastal waters of the Yellow Sea in spring and autumn from 2013 to 2015. Over this period, 4 Paralarvae were collected. Paralarval density was 0.1 inds./1,000 m and 0.2 inds./1,000 m in autumn 2014 and 0.1 inds./1,000 m and 0.2 inds./1,000 m in autumn 2015. The range of mantle length for paralarvae was from 1.5 to 8.3 mm. Survival temperature (15 24 ) for embryo stage and paralarvae was found in locations shallower than 56 m of depth at stations which were sampled for paralarvae.
