Satellite remote sensing images and their contour maps will be applied to the nowcastand forecast system of fisheries and oceanographic condition in this study. Those datawill be transmitted and broadcasted to fishing vessels by directly communicated satelliteand indirectly Internet homepage. Those useful fishing information can help fishermanto find fishing ground more conveniently and quickly and reduce the operating cost,which make the fishery industry to improve its advantage and competitive power. Inaddition, because of the details on certain biological aspects, such as life-cycle, ecology,population structure, migration paths, and reason for the fluctuation of annual yields arestill unknown, we will continue to carry out research on the population structures andphylogenetic relationships between the grey mullet and Herring and Squid species in thesurrounding waters of Taiwan.
