Transgenic Medaka, Small Fresh Water Teleost (Oryzias latipes), is Now Available for Environmental Science

Recently, small model fish, medaka and zebrafish, have been casted a light on environmental science. Transgenic technique is a method that introduce exogenous gene into host genome and enables to generate unique model creature. Adapting transgenic technique on these fish, they become more powerful tool for evaluating aquatic contamination. Chemical analysis and in vitro bioassay, such as ELISA, and analysis with wildlife are popular methods to assess contamination in aquatic environment. In addition to these conventional methods, transgenic fishes are casted a spotlight to facilitate to evaluate aquatic contamination with living creature. In this paper, recent works of transgenic medaka on this issue are introduced.
