Book Abundance Indices of Beluga in James Bay and Eastern Hudson Bay in Summer 2004

Download or read book Abundance Indices of Beluga in James Bay and Eastern Hudson Bay in Summer 2004 written by and published by . This book was released on 2005 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes & presents results from aerial systematic line transect surveys of beluga whales, Delphinapterus leucas, conducted in James Bay & eastern Hudson Bay from 7 August to 1 September 2001, and from coastal surveys conducted while in transit to the transect lines. Beluga abundance is estimated using a line transect method. The final section discusses such issues as population trends, limitations of the survey data, and problems in conducting the survey.

Book Land based Observations of Beluga at Tuututuup Nuvunga Southern Ungava Bay Summer 1993

Download or read book Land based Observations of Beluga at Tuututuup Nuvunga Southern Ungava Bay Summer 1993 written by D. W. Doidge and published by . This book was released on 1994 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on catch records, the beluga population in southern Ungava Bay was estimated to contain at least 1 000 individuals before the start of commercial exploitation in the late 1870s (Finley et al 1982, Reeves and Mitchell 1987). During the 1880s, the Hudson's Bay Company conducted a beluga fishery at the Whale River in conjunction with a fishery on the Koksoak. Commercial exploitation continued in the Koksoak and Leaf rivers until the turn of the century, whereupon the combination of reduced whale numbers and the reluctance of the belugas to enter nets led to the closure of the commercial fishery (Reeves and Mitchell 1987). It is unclear whether the belugas which presently summer in estuaries in southern Ungava Bay form a resident stock, or are migrants from Hudson Strait. The low number of beluga which now frequent the Mucalic [Marralik] and Whale Rivers may be due to reduced population size or human disturbance which may have caused the whales to go elsewhere. These rivers are on the sea-route for travel between Kuujjuaq and Kangiqsualujjuaq. A popular charr fishing area exists in the area to the northeast of the Mucalic River. People also hunt seal and gather eggs in this vicinity. Caron (1987) described the behaviour and reaction of belugas to human disturbance at the Nastapoka River, eastern Hudson Bay, but comparable studies have not been conducted in southern Ungava Bay. The present study was conducted at Tuttutuup Nuvunga to document the level of human activity and the frequency of occupation by belugas in the area of the Mucalic [Marralik] River and Whale estuaries.

Book Update to the Proportion of Eastern Hudson Bay Beluga Harvested and Implications for Harvest Allocations in Nunavik

Download or read book Update to the Proportion of Eastern Hudson Bay Beluga Harvested and Implications for Harvest Allocations in Nunavik written by and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The updated information indicated that the proportion of EHB beluga whales taken in the Ungava Bay spring hunt declined from the 10% used in the plan to 8.8%, while the proportion in the Hudson Strait spring hunt increased from the 10% used in the plan to 11.7%, and from 20% to 23.6% in the Hudson Strait fall hunt (Tables 1 and 2). [...] If the 2016 harvest is 98 whales, and the seasonal pattern is the same as in 2014 and 2015, then the estimated total number of EHB belugas harvested by Sanikiluaq hunters would be (4.7 + 2.3) = 7 animals over the life of the 2014-2017 management plan, not the 18 animals as originally assumed. [...] Estimated seasonal breakdown of reported beluga harvest from Sanikiluaq, assuming that the distribution of harvest effort is the same as the proportion of sample kits returned by hunters, and the estimated total number of belugas harvested. [...] Based on the reported 2014 and 2015 harvests and assuming that the seasonal distribution of the overall harvest is the same as the distribution of the skin sampling program, then 83% of the animals are harvested between April 1 to June 30 harvests, and 2.8% of these are EHB beluga whales. [...] Adding in the estimated 6 EHB beluga whales removed in 2014-2015 in Sanikiluaq, results in removal estimates of 8 to 16 EHB belugas over the life of the plan (Tables 5 and 6).
