  • Title: Medaka as a model of transgenic fish.
    Author: Ozato K, Wakamatsu Y, Inoue K.

    Abstract:
    The medaka (Oryzias latipes) is an egg-laying fresh-water fish. We describe the medaka as a model system of transgenic fish in germs of biological characteristics, manipulation of embryos, gene expression in development, and basic research in aquaculture. The fish are small (approximately 3 cm in length) and have a short generation time (approximately 3 months). The eggs are easy to manipulate. A foreign gene (e.g., the chicken delta crystallin gene) is transferred and expressed stage-dependently in development of medaka embryos. Growth hormone genes of vertebrates are transferred and expressed and, in some cases, accelerate growth of the fish. Thus, the medaka is one of the most promising models of transgenic fish for basic research of gene expression and aquaculture.
