Abstract
The relation between the number of mature ovarian eggs (N) of Salangichthys and the body length (L) or the body weight (W) can be expressed by the formula, N=aL?? or N=a'W??', where a, b, a' and b' are constants. The values of these constants were calculated from the present specimens as follows: (A) for Salangichthys microdon (Bleeker), a=0.1890, b=4.130, and a'=449.9, b'=1.129; and (B) for Salanqichthys ishikawae Wakiya et Takahashi, a=0.008275, b=6.208, and a'=654.8, b'=1.8265.
