FURTHER IMPROVEMENT UPON MAINTENANCE OF ADULT SQUID (DORYTEUTHIS BLEEKERI) IN A SMALL CIRCULAR AND CLOSED-SYSTEM AQUARIUM TANK

GEN MATSUMOTO 1 and JUNICHI SHIMADA 1

1 Electrotechnical Laboratory, Optoelectronics Section, Tsukuba Science City, Ibaraki 305, Japan

Ten adult squid (Doryteuthis bleekeri) were put into a small (1.37 m2 in area) circular tank in a closed system. Half of the squid survived 43-60 days, the other half longer. Filtering ability was essential to squid maintenance, and filtering ability was satisfactorily supported by zeolite in appropriate amounts. In long-term (over a month) maintenance, skin damage caused by faint but repeated contacts with the tank walls became a major cause of death. Feeding squid was found to be important for squid maintenance, and live goldfish (Carassius auratus) were found to be satisfactory as food for long-term maintenance of squid.
