MitoSearch: Construction of fish species composition database with environmental DNA using public databases

Abstract

AbstractExisting fish species distribution databases have the following problems: the possibility of species identification errors due to plasticity of morphological characteristics, the impossibility of quantitative composition, and the difficulty of geographically and time-series integrated interpretation. To solve the above problems, we constructed MitoSearch database. It is a fish species distribution database using 2,160 samples of variable regions of 12S rRNA genes amplified by MiFish primers registered at NCBI/EBI/DDBJ, and visualizes the fish species composition data on a map. By integrating a large amount of data registered in public databases, MitoSearch was aimed to provide the comprehensive understanding of spatial and temporal distribution of organisms on a global scale.
