Abstract The genetic engineering industry for ornamental fish refers to the industry that applies biotechnology to ornamental fish to develop new species of ornamental fish. This research has determined that the features of such industry include: high added values, long time for development, long earning period, R&D-oriented, under numerous restrictions and with less energy dependency. According to a literature review and profile of the company, the research found that Taiwan has achieved significant results in terms of genetic transformation and cloning. Taiwan is one of the best countries when it comes to research and development abilities. Glowing fish play an important role in the upgrading of the ornamental fish industry. Also, the government encourages investment in biotechnology industries. In all biotechnology industries, agricultural biotechnology has lower risks and faster output than other medical biotechnology products, and hence agricultural biotechnology has greater development potential. The research suggests that the ornamental fish dealers enhance the participation to industry ¡Vacademy cooperation, cooperating with Academia Sinica, Fisheries Research institute, and the technological platform of ornamental fish genetic engineering industry, to accelerate the schedule of the research and the development of new species. In addition, facing the doubts related to Living Modified Organisms (LMO) in the international community, ornamental fish producers need to develop new technologies to sterilize genetically modified ornamental fish and create a safety evaluation and certification system for genetic-transformation of aqua-cultural animals to avoid or minimize any possible damage of LMO to the environment.
