Abstract
To clarify the maturation process of Pacific saury, Cololabis saira, by surveying in the field is difficult because the hatching period extends from autumn to spring, and the life history of each individual varies depending on their hatch period. Rearing experiments are considered to be very effective for the elucidation of the maturation process, but to breed Pacific saury from eggs to adults in a rearing tank has been successfully carried out only at the Marine Science Museum, Fukushima Prefecture. We are planning to elucidate the maturation process through our rearing experiments; therefore, we reviewed past rearing experiments and field studies of the maturation process. We also introduced our rearing experiments and their objectives.
