| Outline and Purpose of the Course | This course is designed to review the natural mechanisms to determine stock size of fishery important fishes and invertebrates in relation to environments and to discuss about the management policy of environments and biological resources. Particularly, we will focus on relationships between abiotic environmental structures, ecosystems, and ecology of some important species. We also examine the influence of the terrestrial ecosystem including human activities on environments, biological productivity and biodiversity in coastal areas. | ||
| Course Goals | At the end of this class, students are required to understand basic aquatic animal ecology and production mechanisms of fishery important organisms as a basis for studying further marine environmental and managiment issues. | ||
| Schedule and Contents |
1. Production structure of biological resources A food web from primary production to fishes, new production and regenerated production, grazing food chain and detritus food chain and their complex structure are reviewed. 2. Behavior, ecology and survival of fish The behavior of fish is greatly related to their survival. The survival mechanism is analyzed based on ontogenetic development of behavior and learning capability, and characteristics in life history, ecology and behavior of some fishery important fishes. And new technology of stock enhancement of fish by releasing hatchery-raised fish juveniles after behavioral training in a hatchery is discussed. 3. Mechanism to determine year class strength Many kinds of hypotheses to explain the mechanism of the stock size fluctuation of fishery important fish and invertebrates are examined. We particularly focus on reproduction, early life history, early survival, life history strategy, and response to environmental changes. 4. Marine resource management policy The theory and actual situation of marine living resource management presently being carried out are reviewed with reference to the marine protected area and conservation of nursery grounds. Roles of resource management and stock enhancement for sustainable fisheries are introduced. 5. Ecological connectivity between terrestrial and coastal areas Importance of connectivity from forests to coastal waters and effects of human activities is reviewed from the point of environment, ecosystem, substance circulation, biological productivity and biodiversity. We discuss about future ideal integrated terrestrial and coastal zones management. |
