Sammendrag
The exploitation (1967-77) of the Northeast Arctic cod is
splitted in 12 different fisheries. The mesh assessment model
is modified in order to estimate the maturity ogive on the
basis of the length and the age distributions of the catches
from these fisheries. The key fishery in the estimation is the
gi11 net fishery in Division IIa which mainly takes part during
the spawning season. The resulting ogives are similar to those
derived by other methods for the same period. Although the
estimated statistical variations of the results are underestimates
due to unaccounted uncertainties in the fixed input
parameters in the model, the present method may be an alternative
or a check on other methods.
