[Length and weight growth of the Atlantic halibut (Hipoglossus hipoglossus male, female) off Norway according to Devold's data (1936)].

A short review on the behaviour and catching methods for the Atlantic halibut (Hippoglossus hippoglossus male, female) off Norway is given. Series of length and weight growth from 12 to 40 or 30 years of age respectively are submitted to nonlinear regressions in order to determine growth functions suited for optimal adaption. Results are presented in tables and graphs showing the extreme difference of development between the sexes. Finally the weight for age relation is determined in the allover conventional manner as well as for succeeding age groups confirming once more the sexual deviations.
