• It is customary in Hokkaidô to separate the landings of the cod, Gadus macrocephalus, as to whether the fishing ground is a bank or an offing. With a view to study this problem statistically, the author examined 189 specimens from bank and 764 from off-shore regions. As shown in Table 1 and Figs. 1-2, the landing from the former consisted of 2-to 6-year. classes, of which 3-and 4-year ones form the majority. On the other hand, the latter represented 3 to 6 year classes, by far 4 and 5 year ones. The former was on the average greater than the latter of each corresponding year class in total length and body weight.
