Outline and Purpose of the Course Fish and the sea are very familiar to us. Most students belonging to the Faculty of Agriculture, however, lack enough knowledge on fish and the sea to form their own opinions about the food and environmental issues. The lecture outlines fish and the sea without going into details, so as to equip students with a basic grasp of expert knowledge on fish and the sea.
Course Goals To form an overall comprehension from major keywords and the relationship among the keywords. To know typical examples of experiments in key studies. To acquire basic knowledge sufficient to deeply understand English articles on the ecology of marine organisms.
Schedule and Contents Lecture 1: Introduction (Tagawa) describing the physical and chemical nature of the sea, by comparing marine and land environments from biological viewpoints.

Lectures 2 and 3: Primary and secondary production in marine ecosystems (Suzuki) describing the production mechanism of phyto- and zoo-plankton, which support fish production.

Lecture 4: The diversity of fish and taxonomy (Kai) describing the basic rules of taxonomy required to understand biodiversity, and providing an overview of fish diversity.

Lecture 5: Phylogenetics and evolution of fish (Kai) providing the basics of phylogenetic inferences that estimates the origin of living creatures, and describing evolution of fish based on the phylogenetic reconstruction.

Lectures 6 and 7: Population structure of fishes (Nakayama) describing the factors in the formation of intra-specific populations, the necessity of the study of population structure, and research methods.

Lecture 8: Early life stage (Tagawa) describing the outlines of developmental process, the types of egg, larval stages, and metamorphosis, of fishes.

Lecture 9: Transportation and migration (Tagawa) describing the transportation of larval fish, as well as the smoltification and global migration of salmonids.

Lecture 10: Reproduction (Nakayama) describing diversity in fish reproduction, the difference between underwater and terrestrial environments in reproduction, and decisive factors in reproduction.

Lecture 11: Underwater visual census of fish communities (Masuda) providing an introduction to the method of underwater visual census, with examples of research that uses this method.

Lecture 12: Observation of fish behavior in aquaria (Masuda) describing the research approach from the perspective of fish psychology, which applies methods of experimental psychology to fish in aquaria, with examples of research on schooling behavior and response to predators.

Lecture 13: Connectivity of hills, humans, and oceans (Nakayama) introducing the concept of the connectivity of hills, humans, and oceans, and providing an explanation of the ecological features of estuaries, which is of particular importance.

Lecture 14: Aquaculture (Tagawa) The strategy of stock-enhancement in fishery includes juvenile fish production from eggs, release into the sea, and recapturing after growth. We examine the relationship between human activities and ecosystem of the sea, using stock-enhance project as an example.

Lecture 15: Feedback. Each teaching staff collects e-mails containing questions about the lectures after the exam and model answers for a set period of time, and then returns their responses.
Evaluation Methods and Policy There is no exam at the end of semester. Each teaching staff assesses students' performance by means of class performance (0%-30%, dependent on each teaching staff), occasional reports (0%-100%) and occasional exams (0%-100%). The marks provided by all teaching staff are aggregated to produce a final mark. Assessment criteria and policy are drawn from "Assessment criteria and policy" in the current version of the Faculty of Agriculture Student Handbook.
Course Requirements First year and second year students cannot take this lecture.
Study outside of Class (preparation and review) Before attending a lecture, make sure to review the previous one based on your notes and the handout.
