Regarding to the geographical environment, Taiwan has ocean currents, such as the Kuroshio (the Japan Current), that go by regularly. Such an environment offers a good habitat to many kinds of fish and shrimp, and also provides a good opportunity for fisheries to establish themselves in Taiwan. However, due to limitations imposed by international fisheries management and the “Catch quota management system,” offshore fishing has decreased in recent years. For Taiwan, aquaculture fisheries have to be developed instead. Such aquaculture fisheries also need to be transformed by implementing modern technologies in order to face the competition of fish alternatives as well as international competition. Therefore, this study investigates the local culture flow of Queensland grouper in Ping Tung through on-site visits to assess the actual situation. Wireless sensors called “Tmote Sky” were used in this study. We expanded the use of the sensor by joining an additional self-made water oxygen sensor. By setting up this wireless sensor network, the detected data was sent to the user graphic interface. We could monitor the dissolved oxygen water quality to reduce the death rate of the fish.
