This conclusion presents some closing thoughts on the concepts covered in the preceding chapters of this book. The book argues that trends in artificial reef research would continue with an emphasis on gleaning a better understanding of settlement mechanisms, fishery production, and environmental impacts of human activities. It takes a critical, long-view approach to long-term solutions toward improving fisheries by suggesting large-scale artificial reef deployments to create extensive fishing grounds. The book offers an excellent example of how future evaluations of fisheries data may take place. It introduces the countermeasure technologies that are being promoted in Japan. The book proposes that creating new habitats (e.g., similar to the habitat creation in artificial reef deployment) can take place in a sensible manner and with consideration given to fishermen. It shows that Fisheries Engineering can make considerable contributions to the future direction of energy savings and, indirectly, help improve the environment.
