Steroid Content of Some Species of Deep Sea Fish in Western Sumatra and Southern Java Ocean

Abstract

In this research, some researchers suspect steroid hormone content on Bathypteorois and Erimoensis species of Bajacalifornia atricolor. The purpose of this research is to know steroid content. This research used the 11 species of marine fish in the Western ocean obtained in Southern Sumatra and Java through research vessel Baruna Jaya IV, in September and October 2004. The species are Alepocephalus bicolor, Antigonia rubescens, Barbourisia rufa, Bajacalifornia eromoensis, Caelorinchus divergens, Polymixia sp, Rouleina guentheri, Setarches guentheri, Synagrops japonicus, Tydermania dalgleishi and Xenolepidichthys. From the results of proximate analysis, the nutrient content in some marine fish are 11.94-20.81% protein contents, 0.01-4.84% fat contents, 73.29-82.73% moisture contents and 1.07-2.49% ash content. On analysis of HPLC (High Performance Liquid Chromatography) the fat contents of steroid obtained are between 0026-0.016%. Deep sea fish species that assumed have steroids compounds are Bajacalifornia eriomoensis, Caelorinchus divergens, Tydermania navigatoris, Roulenia guentheri, Antigonia rubencens, Alepocephalus bicolor and Synagrops japonicus. Bajacalifornia erimoensis showed the best results on HPLC test so it continued with infrared test to show the similarity of steroid group.
