抄録

The Brain Science Institute was established to understand the brain using by cephalopod models and employing both ethological and molecular approaches. A special facility, the Center for Squid Culture and Behavioral Research, was opened in January 1999. The initial work dealt with technical problems such as methods of squid transfer, type of aquaria used, and type of diet. Several types of closed-system aquaria are used: a large circular tank (10, 000 l) ; a small circular tank (1, 700 l) ; and cylindrical tanks (eight 20 l or eight of 50 l) . Two species of squids (Heterololigo bleekeri, Sepioteuthis lessoniana) and cuttlefishes (Sepiella japonica, Euprymna morsei) were hatched and cultured from eggs, and wild-caught adult H. bleekeri, S. lessoniana, Todarodes pacifiacus and Idiosepius paradoxus were also maintained. Hatchlings of S. lessoniana and S. japonica were successfully cultured in cylindrical tanks for multiple generations. Heterololigo bleekeri hatchlings survived beyond 2 months in cylindrical tanks. Adult squids were successfully maintained in the large tank for the following durations: H. bleekeri, 78 days; T. pacifacus, 21 days; S. lessoniana, 5 months; I. paradoxus, 54 days. A wide variety of experiments can now be undertaken using live squid and cuttlefish at this facility, but some modifications are still needed for culturing more delicate species such as H. bleekeri.
