Transgenic aquatic organisms (aquatic genetically modified organisms, aquatic GMOs) have become an important role in academic researches and industrial potential competitiveness. But if transgenic aquatic organisms escape from farms, they could encounter and interbreed with natural populations. For preventing serious impacts caused by aquatic GMOs on the ecosystem, the Mariculture Research Center, Fisheries Research Institute, C.O.A., E.Y. set a well-isolated and standard-qualified experimental structure - "Genetically Modified Aquatic Organism Facility" ,providing an access to assess the risk about aquatic GMOs. The tasks in this year are (1) building the capacity, (2) measuring trait values under relevant environmental conditions that take into account the phenotypic effect of the transgene, (3) evaluating the biosafety risks to the environment identified and the measures which might be taken to minimize these risks, and(4)acquiring international certification for the detection of GMO's transgene expression.
