The </em><em>dog conch</em><em> culture is needed to maintain their population. The technology towards </em><em>conch</em><em> reproduction is still not developed yet in Indonesia. The </em><em>17β-estradiol</em><em> hormone in conch and some mollusks has been stated by some researcher yet its main role in conch reproduction process has not widely known. The study about the addition of </em><em>17β-estradiol </em><em>hormone in accelerating gonad development has never been reported. The aim of this study was to evaluate the impact of the addition of </em><em>17β-estradiol </em><em>against dog conch’s gonad development. This study used three treatments for three groups of dog conch </em><em>those were</em> <em>without</em><em> inject</em><em>ion (P1), </em><em>inject</em><em>ion </em><em>by </em><em>30 µL</em><em> of corn oil mixed with </em><em>absolute</em><em> ethanol</em><em> (P2)</em><em>, and </em><em>30 µL </em><em>of </em><em>17β-estradiol stock solution (P3)</em><em>. </em><em>After injection, t</em><em>he dog conch </em><em>w</em><em>as reared in </em><em>pens</em> <em>culture</em><em> in </em><em>their natural habitat </em><em>for 30 days. </em><em>This study showed that the injection of </em><em>a </em><em>17β-estradiol solution (P3) stimulated </em><em>the dog conch’s gonad development </em><em>as evidenced by greater oocyte mean diameter than</em> <em>another treatment</em><em>. The mean of gonadal weight and GSI on P3 treatment was also </em><em>higher</em> <em>than treatment</em><em>s</em><em> P1 and P2.</em> <em>SDS-PAGE</em><em> analysis showed that dog conch’s hemol</em><em>y</em><em>m</em><em>ph</em><em> has several kinds of proteins with varying molecular weights</em><em>.</em> <em>P</em><em>rotein</em><em>s</em><em> with a molecular weight </em><em>of 54-55 kDa</em> <em>are</em><em> predicted as dog conch’s vite</em><em>l</em><em>logenin.</em></p&gt;}, number={3}, journal={Jurnal Ilmu dan Teknologi Kelautan Tropis}, author={Muzahar and Zairin Jr.Muhammad and YuliandaFredinan and Suprayudi Muhammad Agus and Alimuddin and EffendiIrzal}, year={2019}, month={Dec.}, pages={583-593} }
