Identification of the spaghetti eels (Moringua Sp) at Pelabuhan Ratu, Indonesia using mtDNA control region sequences

Abstract

Eels are economic species of fish. The diversity of eel in the world is essential knowledge that we have to know to manage fisheries in the future. One of the types of eels is Moringua Sp. There are around 11 species of Moringua sp. in the world. In Indonesia, the diversity of Moringua sp. was no information yet. The aim of this study is to the identification of Moringua sp in Indonesia. The method used in this study is a sanger sequence method using the mtDNA control region. Base on this study, we found 726 and 745 base pairs alignment of Moringua by sequencing. The result of BLAST showed identically 87% to Moringua edwardsi and 89% as a Moringua microchir. The low percentage of BLAST yields shows that the sample used for this study is not strong enough to be declared as one of the Moringua species obtained from the results of BLAST analysis. Suspected of being another Moringua species. Thus, to get robust result, further research related to this species identification using COI or Cyt-b.
