| 内容記述 | In order to determine the cause of present difficulties in abalone resource enhancement, the long term activities of seed transplantation have been reviewed and analyzed from an eclogical point of view. Despite the long term effort of artificially produced abalone seed transplantation in Japan, recent annual catches of abalone have declined from 5,000 tons level to 3,000 tons. This marked decline of the annual catch has occurred from 1980 when the intensive transplantation of seed abalone has been increasingly undertaken throughout Japan. Consequently it has become clear that seed transplantation dose not contribute to the enhancement of the natural abalone resources. However, the transplantation of these seed abalone were not designed to recruit to the natural population. Rather these attempts have been to promote the fishing grounds utilization for the one generation of the seed abalone that were released. Subsequently the research effort on the influence of transplantations on the natural population or on its abundance has not been marked. Although recaptures have brought a faintly profitable turnover in the case when larger size seed of more than 3 cm in shell length were transplanted, the wild population did not increase. Based on new information on the ecological role of the algal community within the rocky reef ecosystem, a theoretical approach to the ecological management and utilization of seed transplantation aimed at an establishment of self sustainable natural spawner population are discussed in order restore natural abalone populations. | |||||||||
