This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to estimate current population size of Northwest Atlantic harp seals using an age structured population model, incorporating recent estimates of reproductive rates, unreported mortality, and pup production. Replacement yields (in units of total removals) and the corresponding levels of reported catch in the Canadian Front and Gulf that would provide such yields are calculated, assuming that other hunt components take the same number of animals as each component did in 1999. In addition, the study presents an estimate of population size in 2005 and 2010 if these replacement yields are taken in the intervening period. Uncertainty in these estimates was determined incorporating the error associated with the available pup production estimates.

This book was released on 2013 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: A population model was used to examine changes in the size of the Northwest Atlantic harp seal population between 1952 and 2012. The model incorporated information on reproductive rates, reported removals, estimates of non-reported removals and losses through bycatch in other fisheries to determine the population trajectory. The model was fit to eleven periodic estimates of pup production from 1952 to 2008, and to annual pregnancy rate data collected between 1954 and 2012. The harp seal (Pagophilus groenlandicus) assessment incorporates information on annual age specific reproductive rates, reported harvests, struck and loss, and ice-related mortality of young of the year (YOY), into an age-structured model to estimate total population size. The model is fitted to estimates of pup production obtained from aerial surveys and mark-recapture studies by adjusting the initial population size in 1952 and adult mortality rates.--Document.

Book excerpt: Information on catch levels and the age structure of the catch (catch-at-age) is necessary for accurate population estimation and responsible management of the harp seal (Phoca groenlandica) in the Northwest Atlantic. Harp seals are hunted off southern Labrador and the northeast coast of Newfoundland (the Front), in the Gulf of St. Lawrence, along west and southeast Greenland, and the eastern Canadian Arctic. This report summarizes available harp seal catch and catch-at-age statistics from 1952 to 1999 for each of these areas.
