Estimates of pup production, age at first parturition and natural mortality for hooded seals in the West Ice. A deterministic population model for females

Frequencies of age group 1 were calculated from the number of seals in the total samples while frequencies of age groups 2-5 were calculated from the number of two year and

Satellite teleinetry studies of adult hooded seals from the West Ice were reported (Folkow and Blix, 1993). While several of the seals remained in or near the sea ice edge,

The general distribution pattern of these standard deviations was· fairly similar from year to year, indicating that the average values could be used for the

Estimates of total mortality coefficients (Z) were calculated from English, German and Scottish age compositions per unit, fishing effort. The age groups chosen

The calculated total stock size in weight of four year old and older herring from cohort analysis for two alternatives of natural mortality compared to the
