Outline of Final Research Achievements

The aim of this study is to evaluate the environmental response of reproductive traits in Japanese anchovy Engraulis japonicus under captive conditions. Expression analyses of reproduction-related genes were also undertaken to enable to quantitative evaluation of the environmental response of reproductive traits. In individuals reared in the low-temperature condition, the body size (total length) of puberty onset was larger compared with individuals under natural water temperature. In addition, lower growth rate, slower increase of condition factor were observed in individuals under the low-temperature condition. The database of reproduction-related gene was constructed by transcriptome analyses using next-generation sequencer.
