520 |a"This document reviews the research on grey seals conducted in 1978 and presents a new assessment of the eastern Canadian population. The revised assessment is based on the results of two years of complete cohort tagging on Sable Island (see Figure 1) and a revised natural mortality rate as developed in Harwood and Prime (1978). The latter rate is about two-thirds of the value used in the 1977 assessment (Gray 1977) and the subsequent virtual population analyses seem to better reflect what is known about the population. Though the analyses give reasonable estimates of the order of magnitude of the population, there are still wide ranges for the estimated numbers. Research in the next few years will be aimed at narrowing these ranges"--Introduction.
