Abstract

The occurrence of eggs of hairtail, Trichiurus japonicus was examined in the coastal waters of Jeju Island, Korea in spring from May to June in 2014, April to May in 2015, and April to in 2016. As a whole, hairtail eggs occurred abundantly in May, 2014. Especially, high densities over 300 ind./1,000 ㎥ of eggs abundances in May and June, 2014 occurred in the north-western area of Jeju Island where is upwelling phenomenon occurred throughout the year. In the relationship between T-S and the hairtail eggs abundances, high densities over 100 ind./1,000 ㎥ of eggs abundances occurred in temperature of 18.1-18.7℃ and salinity of 33.92-34.87‰ in May when hairtail eggs occurred abundantly.
