| Outline and Purpose of the Course | A broad overview will be given of the physiological phenomena found in aquatic organisms, particularly fish and shellfish, which are useful for fishery resources. | |||
| Course Goals | To first understand the overview of the important physiological phenomena found in individual fish species from the main keywords and their inter-relationships. To also grasp specific examples of experiments for characteristic research. Then, to acquire the basic knowledge for independently working on the original English paper on fish physiology in 4th year after being assigned to a laboratory. | |||
| Schedule and Contents |
Lectures 1-2: Neuroendocrine system The lectures will outline the central nervous and endocrine systems that integrate physiological mechanisms at the individual level. In addition, we will outline the mechanism of action of bioactive substances, including why the endocrine disrupters work. Lectures 3-6: Reproduction Aquatic organisms have interesting reproductive patterns, such as hermaphrodism and transsexualism. Learn how sex determination, oogenesis, and spermatogenesis work as a basis for understanding biotechnology such as cloning and triploids. Lectures 7-9: Growth and metabolism It is not uncommon for aquatic organisms to grow 100 times or more without any inconvenience due to the turning point of metamorphosis. The lesson physiologically explains the mechanism of metamorphosis and growth and the digestion and metabolism that support it. Lectures 10-12: Osmoregulation and migration Many saltwater species cannot survive in freshwater; likewise, many freshwater species cannot survive in seawater. We will explain the ions and water loading and unloading mechanism, which is the key to this phenomenon. Using migratory fish as an example, we will consider the mechanism of adapting from freshwater to seawater and the meaning of "migration." Lectures 13-14: Respiratory, circulatory, and motor systems For animals to survive in water, where the oxygen concentration is much lower than in air, they need an excellent oxygen absorption and transport mechanism. We will also explain the mechanism of the muscle system suitable for the efficient use of the obtained energy. Lecture 15: Feedback Lecturer will wait in his laboratory at an assigned time after the exam for students' questions to answer. We will respond to oral and e-mail questions throughout the entire lecture period. |

| Evaluation Methods and Policy | Attendance records will not be taken. An absolute evaluation with a raw score will be performed based on the final exam and the reference memo described later. The evaluation criteria and policies are based on those described in the Student Handbook of the Faculty of Agriculture for the relevant academic year. | |||
| Course Requirements | None in particular | |||
| Study outside of Class (preparation and review) |
Before the class, please review the notes and handouts of the previous class. For the test, students are allowed to have a reference memo (completely handwritten, covering up to both sides of one A4 sheet. Copies are not allowed). The exam will be answered with reference to this memo. This memo should be submitted with the exam answer sheet, and will be added to your grade. |
