Abstract
The paper presents the resultats of the observation on the 
maturation stage in the species Ommastrephes bartramii caught in
January-April, 1978, in the southwestern area of the Atlantic
Ocean, on the high seas. The ratio of nidamental gland length to
mantle length was determined by measurements, as well as the relat-
ionship between these parameters at different maturation stages.
The maturation ratio (m) is a significant index for a more precise
determination stage in female Ommastrephes bartramii both in field
and laboratory conditions.
