The objectives of this study are establishment of genetic stock and cultural techniques ofIvory shell, Babylonia areolata, Octopus spp.andcoral trout, Plectropomus leopardus.The stock will be collected and preserved for utilization of researchers. The tank system,diet, growth, mature size, spawning season, embryonic development, hatching, andlarvae rearing will be studies. The knowledge will be very valuable for the mass seedproduction. It is also needed to study monitoring and stock assessment on Octopus spp.fishery resource in the water of Peng-Hu. These investigated data will provide the fisheryadministration to establish the management policy for Octopus spp. fishery.The coral trout, Plectropomus leopardus, is an important commercial species and verymuch relished sea food in Taiwan. As the supply of wild fingerlings is limited anduncertain. The growth of the grouper farming industry in the region has been hamperedby the shortage of fingerlings. There is therefore a need to establish breeding techniquefor mass production of coral trout fingerlings. We have to study the development ofembryos, larval rearing, established the broodstock of parent fish, and keep good qualitygenetic strain in a role of aquaculture. For improve the techniques of coral trout cultureand produce mass seed.
